If you are new to Autodesk Revit Architecture and like my teaching style, you may be interested in my free comprehensive Online Beginners' Course. I created a family to express a object then nested that in a child family. • Provide a complete list of all Shared Parameters used by Revit on export including ALL properties defined in IFC PropertySet Definition for both Instances and Types. In some cases, it can be convenient to represent parts of the nested family separately from the main family model. This makes it flexible in the project environment rather than requiring users to. Open the original shelf family and save it as the second shelf option. In the Revit software, these system families are in-built in it priorly. Lookup Tables and a Little Chat - Getting the Type Name into a Text Parameter I've very recently been looking at using Revit lookup tables for structural families. Level of detail. Notice that the formula begins with an equal sign (=). When creating complex families this tool gives the user unprecedented control over parameter associations within nested families. By default, the elements of the input that are occupying the same index position are combined together in the node function. Although Revit supports parameter names with spaces, I think having your parameters as one “word” makes writing formulas easier. In my particular case I have the panels as a type parameter and the hardware as instance based. Project information and sheet parameters can now be exported as PDF properties and used by your document control software. Notice the Parameter Types section of this Parameter Properties dialog box (see Figure 8). The array count will change depending on dimensions changing in the host family. Here is the list in the family: and here is what i have: But i get null with the “Family. Example on how to use it in formula, for example in schedule or in family (when using as shared parameter of AREA type called ElementFlippedOrMirrored). This is a Revit family inside a Revit family definition… or nested family. In this tutorial, I show you how to create Wall elements- including how to control their placement both horizontally (Location Lines) and vertically (Top / Base Constraints) Unit Agenda […]. The way the height scaling works is a bit tricky to explain. Once you’ve flexed the model enough and are comfortable it won’t “break”, you can go ahead and create a few family types. The name of the types should be easily understood by future users of the family. Starting in the early 1980s, IBM APL development, under the leadership of Jim Brown, implemented a new version of the APL language that contained as its primary enhancement the concept of nested arrays, where an array can contain other arrays, and new language features which facilitated integrating nested arrays into program workflow. It is an irrational number, but if we truncate it to 20 decimals it would be 2. Parameter formula using IF to check a Yes/No parameter Hey, I am quite new to Revit but am familiar with parameteric modelling from Inventor (which doesn't seem to be completely helpful). Background High‐density lipoprotein (HDL) cholesterol has inverse association with cardiovascular disease. Make a system type parameter into an instance parameter, select dimension with a label in view, check instance parameter in option bar. For this example we are creating a line type that has text in it. This will allow visibilty control of the lines once nested; This now completes the 'plane' family. Select Family Types in the Design bar. Family API Webcast and. I tend to build one family with many uses and types. You are in for an exciting ride!. This course covering everything you need to know to get started with Revit Content Creation. Parameters are case sensitve. In case the sheet contains multiple rows with the same type parameter, the import to Revit writes back the value from the last line. Create specific families, including in-place families, profiles, annotations, and parameters. The double door family may contain numerous other configurations. There are 3 kinds of families in Revit: 1. All planting families have a type parameter called "Height" baked into them. Shared families can only pass (forward) instance based parameters. These parameters can be viewed in the Family Types dialog. In this blog, ATG Technical Specialist Quentin Worm demonstrates the different formulas you can use in Revit family parameters. Enroll into revit architecture training in Nepal.

However, if you don’t need a thickening Revit 2012 allows you the ability to create families with Voids that can cut multiple elements in the project: Create a new Generic Model family - I like to use face based; Add reference planes to control its length and width by instance, and its depth by type. The lists are included in the installer and will be placed in the install folder: IFC Shared Parameters-RevitIFCBuiltIn_ALL. You can make the nested-family dependent on the code-drucker parameter. • In the Family Type dialog and a formula as shown below. Family Types Toolbar. You can create families that feature interchangeable nested components when added to your projects. The family can be complex, but not complicated. Project information and sheet parameters can now be exported as PDF properties and used by your document control software. We will talk about Nested Families and how they can be utilised to cut down on your modelling time. …So in this movie we're going to look at using parameters in the host Family to…drive the values of parameters in the. Analyzing Basic Walls. of Reviteristics - An Opening isn't a Door on Revit OpEd. But, if you are really into Revit, there are not many choices. Visibility / Graphic. date_constant. Main type parameters are Pipe Size and Gap between pipe and the wall, which also drives the size of the void that cuts the wall. Make it Instance-based and a Text parameter. static Node * build_coercion_expression(Node *node, CoercionPathType pathtype, Oid funcId, Oid targetTypeId, int32 targetTypMod, CoercionContext ccontext, CoercionForm cformat, in. When creating families containing nested families with varying family categories [for example the main family is a generic model category with a nested furniture category family] ensure that the nested family is set to shared under Category and Parameters > Family Parameters. We explore formulas, family type parameters, materials, and even dabble in some trigonomic functions. Exponentiation X raised to the power of Y = X ^ Y. There are a couple ways to make the nested families adjustable from the project. Loadable families can be combined to create nested and shared families. Visibility / Graphic. The name should clearly indicate the difference between each type and briefly describe the parameter value that changes. Moving further below mentioned are the types of Revit Family Creation Services. Improves data integrity when copying or reloading groups that contain shared nested families between projects. Once you’ve flexed the model enough and are comfortable it won’t “break”, you can go ahead and create a few family types. The parameters must be coordinated with the family to allow the two to communicate. If so the user supplied good data and the model text should read "GOOD". The advanced sample family (rac_advanced. E is a mathematical constant that is approximately equal to 2. Create, manage and modify parameters. Before discussing Families, we need to discuss Types in Revit. Arrows shows the possible rotation of family: If you rotate family clockwise - Family Rotated = 90° If you rotate family counterclockwise - Family Rotated = -90°. Use Type Parameters. Click OK again to close Associate Family Parameter dialog. Name of a constant that has a date data type. We have an associated parameter called, “Head Trim Type”, and this parameter is a parameter. Lookup tables are used to define parameter values in an external comma-separated values (CSV) file. Using Array and Formula in Parameters Creating Array. Be aware that nesting certain formula’s and families can impact performance in Revit so first test the family performance in a project environment before handing it to the team. Doing so allows us to adjust the material of individual faces within the. Then I nested the child family in my parent family. Creating the nested “tag” is very similar to creating a typical tag family. See Document Model: Parameters to learn how to edit parameters of an element type. When creating or editing these parameters, the user is given the option to assign each a formula, enabling constraints or allowing various parameters to respond to each other. Introduction Walls are arguably one of the most important elements of any building. Pushing multiple parameters to multiple Revit family files is a powerful function that is made possible by the Revit Extensions tool. All of the Revit tags and symbols are annotation families. With the design of this chair, the legs are going to land right in the middle of the arms. remains a desirable constant and let Revit calculate the Array Count. Starting in the early 1980s, IBM APL development, under the leadership of Jim Brown, implemented a new version of the APL language that contained as its primary enhancement the concept of nested arrays, where an array can contain other arrays, and new language features which facilitated integrating nested arrays into program workflow. Type Parameter A Type Parameter is common to a type of door. You know who you are. Add the following formula to the Remainder parameter Width - Double Hung Width. These refer to three preset choices for the orientation of a family. Nobody knows why, but in Revit when dealing with visibility parameters we have to miss “If” at the begging. Join Paul F. loadable families 3. If you had a chair type with legs that were a certain height. Go back to Family Category and Parameters > Generic Models > Doors > OK; Go into your Family Types. In the Family Type dialog, click New Type. date_function_call. Open edit the parent family and load the family into it (nested family). Flexing the Model Flexing Rules. Select the planting family and link its "Height" parameter to the new reporting parameter in the pattern family; you may need to add a formula to scale it up or down to match the size of the pattern grid (depending on the original family size) Create a new mass family or In-Place mass within a project;. I’m not even sure whether that’s possible and next to that it won’t be necessary. Substring(4. Parametric families. In that case, only the 2 nested door families would schedule. The type Parameters are greyed out. These parameters can be viewed in the Family Types dialog. Example on how to use it in formula, for example in schedule or in family (when using as shared parameter of AREA type called ElementFlippedOrMirrored). Change a Type Parameter and all Instances of the that Type will also change. Type catalogs allow families to use large (or small) preset data tables to populate the parameter values. Type: Parameter modifications are global for this family type Instance: Each family of this type could have a different value without creating a new family type. Revit beam family Revit beam family. The tutorial is available here: Nested Families & Arrays Just in summarisation though, best practices when creating parametric arrays: 1. General rule of thumb until recently when using SHARED nested components: Type parameters can be accessed through the project, instance parameters need to be tied to the parent in the Family Editor. Parent function equation. Improves stability when loading a family while adding a Family Type parameter. For the naming of families and types, try to use a type coding that is clear for the entire team and fill the family with sample types before loading it into the project. This means all parameters of a nest that are to be mapped must be instance-based values. So you see – the comma (from the first row in the txt file) automatically represents the Family Type name. Enroll into revit architecture training in Nepal. Parameter formula using IF to check a Yes/No parameter Hey, I am quite new to Revit but am familiar with parameteric modelling from Inventor (which doesn't seem to be completely helpful). E is a mathematical constant that is approximately equal to 2. Hope its clear now. There are a couple of new family templates provided for creating these families - Generic Model line based. Either A or B can be picked through a "Family Type" parameter. For this example we are creating a line type that has text in it. Building Chair Legs and a Nested Family Tutorial Step 1: Create a reference plane for the arm width. In my case, I've used a solution for Autocad, and used *. In the component family environment, Revit won’t allow you to formulate the material parameter. HOW TO USE PARAMETERS TO CALCULATE VALUES IN THE FAMILY TYPES DIALOG. Create family types. What is the difference between instance and type parameter in Revit? Answer Instance Parameter – Enables you to modify the parameter value separately for every instance. Name of a constant that has a date data type. Note: It may be beneficial to create a directory structure whereby the Nested families are a sub-directory of the Host family. Family API Labs: Creating an Example Family. Create a new family from the 'Metric Generic Model' template; Under 'Family Category and Parameters', uncheck 'always vertical' and check 'work plane based' Add a family parameter 'Length'. Like in this topic: Adding Multiple Parameters in the Family Editor Now i try to set a list of values to the parameters. Change a Type Parameter and all Instances of the that Type will also change. For Revit, cost is just a multiplier of the Area (cost really has no unit value in Revit) so Revit wants a Area in the end because that is all it knows. As you will see in this example, you get the benefit of not having to "normalize" or remove the units of another parameter when using it in a formula and you can change the format and have the value automatically change. It’d also be fine to only read and change these parameter values. However, you cannot nest a Shared detail item family in a 3D family. Voids cannot cut nested families. com Revit consists of three types of parameters: Instance, Type (Family or Shared), and Global. When creating geometry for a Revit family, dimensions can be converted into dimensional parameters for the family. I can't say it's very inconvenient, but can't say it great either. Family Type parameters are the most powerful, and the most restricted type of parameter in Revit. Before discussing Families, we need to discuss Types in Revit. Clicking Edit Type opens the Type properties dialog box of the selected component and displays its user-editable and read-only properties (see Figure 16). The tag opens in the Revit family editor. In that case, only the 2 nested door families would schedule. Green-colored parameters in the Excel sheet can be edited and then imported back to Revit using the function "Import schedules". Evaluate those other parameters, and you get the same effect as long as their values remain unchanged. Set up a component family file with a parametric framework. In Revit, arrays can only have an integer value of 2 or greater. Revit comes bundled with a number of pre-made artificial light families for wall, ceiling, table, exterior, as well as other types of lighting, which are available for your projects. For this example we are creating a line type that has text in it. Open the FAMILY TYPES dialog box and create three Family Types with the following properties. Introduction to Revit Family Creation. 0, and the end value is 1. Revit asks for the type name. Once loaded into the family, enter the desired formula under the Formula column. Voids cannot cut nested families. Check Box Length Yes/No Tick Text. Now you have a parameter 'type' with a drop down list where you can choose '100mm' or '50mm'. If you've set up a Revit family before, remember that you have to assign a parameter type (string, number, dimension, etc. Let’s take a window family for example: STEP 1: We have an associated parameter called, “Head Trim Type”, and this parameter is. R&D Objectives. For Revit, cost is just a multiplier of the Area (cost really has no unit value in Revit) so Revit wants a Area in the end because that is all it knows. To make the parameter editable, remove the characters in the Formula for the parameter you would like to make editable. 1 tutorials revit architecture revit arrowheads revit bim revit change camera position revit content revit countertop revit create grip family revit view title revit cross section views revit custom arrows revit custom view tag revit dimension at an angle revit door renumber revit dormer cut roof revit drafting view referencing revit walkthroughs revit family revit libraries revit.

How to Add Rotational Parameters to Nested Geometry in Revit Families The ability to set rotation parameters for an object in Revit is an important skill to know. Family Name and Type. With the clever use of array formulas, visibility formulas, nested families and labels, on can create many types, even if they differ slightly, from each other, with ease. Improves data integrity when copying or reloading groups that contain shared nested families between projects. com Revit consists of three types of parameters: Instance, Type (Family or Shared), and Global. These parameters can be viewed in the Family Types dialog. Parameters are typically created in the Family Types Editor (see Figure 5). Tiada ulasan: The Revit Kid Visibility Parameter Revit Tutorial; Revit Families families, formula, formulas, instance parameters, type parameter No Comments Driving the Visibility of a Nested, Nested Shared Family where Hosted in a Curtain Wall Panel Door March 16, 2017 May 8, 2017 Luke Johnson. Flex the family (test parameter values against the model geometry). The Plan Scale parameter will be used as a mechanism for the user to convey the view scale to the family. There is a difference. static Node * build_coercion_expression(Node *node, CoercionPathType pathtype, Oid funcId, Oid targetTypeId, int32 targetTypMod, CoercionContext ccontext, CoercionForm cformat, in. Actually, there is no way to make a family recognize the type of host wall, but can make it recognize thickness of it by using 'reporting parameter'. Nobody knows why, but in Revit when dealing with visibility parameters we have to miss “If” at the begging. Place the array like below. It's easier than it sounds, just follow the steps below. In the nested family this controls the height of the stick. Revit does this because the nested type parameters cannot be shared in the host family. Type name, parameter value 1, parameter value 2, parameter value 3. A good way of having consistent data associated with certain families is to add a nested family with the desired shared parameters into the host manufacturer family you may have downloaded. For more information about entering formulas, see Valid Formula Syntax and Abbreviations. Downloads section where members can share many types of contents: BIM objects (ex. txt file will tell Revit® what values to apply to the various Type parameters within each family type so that the family types match the properties in the. Parameter formula using IF to check a Yes/No parameter Hey, I am quite new to Revit but am familiar with parameteric modelling from Inventor (which doesn't seem to be completely helpful). Either A or B can be picked through a "Family Type" parameter. In this blog, ATG Technical Specialist Quentin Worm demonstrates the different formulas you can use in Revit family parameters. There are several types within family: Geometry is driven by type and instance parameters, and using them a whole geometry can be adjusted. Masonry walls usually have specific thickness depends on brick size. Re: Controlling nested Family Type parameter with a forumla referencing another Family Type parameter So in additional offline conversations with Alfredo about my specific family, it came to light that the EF family needs to be built so that it is able to be hosted by a horizontal plane. Revit families), documents, applications and plugins. Unfortunately, if a family is marked to be shared then type-based parameters can’t be mapped in the host. See Labeling Dimensions. This mimics what you would have to do in real Revit as well - reading a formula is doable in the project via edit type, setting the formula requires opening the family in th family editor. Shared families can only pass (forward) instance based parameters.

HDL possesses anti‐inflammatory properties in vitro, but it is unknown whether this may be. Parameters in Autodesk® Revit® allow control over elements and information with constraints and controls. Revit Parameter Organizer 2018: Family Parameters - Editor Editor tool in the Editors drop-down of Family Parameters tool-set helps edit all family parameters in the current family model. I have recently updated my tutorial for nested arrays and formulas which was getting quite old. For Revit, cost is just a multiplier of the Area (cost really has no unit value in Revit) so Revit wants a Area in the end because that is all it knows. This will preserve the original tag. Here is the list in the family: and here is what i have: But i get null with the “Family. , PipeSize, WireSize, and Length are both length parameters); we do not create different units for each of these, but instead use the main unit type. Whenever you create an Array, you have the option to turn the array into an instance parameter. Types of Revit Family Creation Services. • This formula will test to see if the parameters of Bookcase Thickness and Bookcase Thickness Actual are equal. There are 3 kinds of families in Revit: 1. These formulas can utilize addition, subtraction, multiplication, division, and some trigonometric functions. The sample family also illustrates the syntax for commonly-used formula types. When creating or editing these parameters, the user is given the option to assign each a formula, enabling constraints or allowing various parameters to respond to each other. Before you alter your families in this way you should be sure to consult with your BIM team and also to review whether the parameters truly need to be specified within the families themselves. In this tutorial, I show you how to create Wall elements- including how to control their placement both horizontally (Location Lines) and vertically (Top / Base Constraints) Unit Agenda […]. Click Family Types from the Design Bar. in-place families Most elements that you create in your projects are system families or loadable families. Nested family – family uploaded to parent family. In this blog, ATG Technical Specialist Quentin Worm demonstrates the different formulas you can use in Revit family parameters. rfa) and click Save. But, if you are really into Revit, there are not many choices. Notice the Parameter Types section of this Parameter Properties dialog box (see Figure 8).

RPC , visibility , FAR (Floor Area Ratio) , feasibility , program , feet units , fences. These are the main topics covered: Creating a Family through the User Interface. Create family geometry. Creating the Family Type. They belong t…. Detail levels determine which pieces of family geometry display in different types of project views. Open the original shelf family and save it as the second shelf option. IMPACT for Revit is the collective name for IMPACTs Revit modules. Use Type Parameters. Doing so allows us to adjust the material of individual faces within the. To control the type of family within a nested family, you create a family type parameter that can be either an instance or type parameter. Patch 3 exposes the reload actions counters on devlink dev get. Create and add a shared parameter in the door families; it could be a Yes/No Parameter called "Schedule". One things that helps, in many ways, is to use the correct units, or type, when creating a parameter. Revit asks for the type name. The code reference and minimum exit separation distance are automatically adjusted/calculated based on the length of the family and sprinkler parameter. Family Type Selector Param = if (Select Type 1 Param, Family Type 1 Param, Family Type 2 Param) Because you can't evaluate the value of a Family Type parameter in a formula, you need other parameters to exist with those values. Using this guide will help to standardize content within the industry, allow greater interoperability between members, and provide detailed metadata to. Usage in Revit = pi () Circumference = pi () * (Radius * 2) Circumference = pi () * Diameter. A family parameter looks a lot like a normal Revit parameter on a BIM element instance, and has many of the same properties such as the Definition property which defines the parameter name and data type. For each species of tree, the stick height is adjusted to match the height of the Render Appearance. Continuing with our parametrically- controlled door Family, in the previous movie…we left off by adding a door panel using a nested Family, and when we flexed it…was rotating and moving correctly [00:00: 153. Typical examples include Windows, Doors, Columns Beams and a wide range of MEP components too. Detail levels determine which pieces of family geometry display in different types of project views. Create family geometry. Main type parameters are Pipe Size and Gap between pipe and the wall, which also drives the size of the void that cuts the wall. In this Revit 2016 tutorial course, Brian DeYoung from SOM will show you how to work with custom families and parameters in Revit 2016. True False. Patches 4-9 add support on mlx5 for devlink reload action fw_activate and handle the firmware reset events. Dicatat oleh Revit. Parent function equation. They are view-specific, adjust with the scale of the view and can be embedded in other families. static Node * build_coercion_expression(Node *node, CoercionPathType pathtype, Oid funcId, Oid targetTypeId, int32 targetTypMod, CoercionContext ccontext, CoercionForm cformat, in. 1: Set up various types in the nested family, then in the main family assign a parameter to control which type is used (see pic #1) 2: Tie the nested families parameters to corresponding parameters in the main family (see pic #2). Change an Instance Parameter and only that specific Instance of the Family will change. Although Revit supports parameter names with spaces, I think having your parameters as one “word” makes writing formulas easier. (If your Title Block family has several family types, you will want to do this for each Family Type. wall, roof, ceiling and floor) Structure Elements: contains elements that are only used in Revit Structure. Flexing the Model Flexing Rules. (If you need to brush up on the basics, video recordings of many Family Editor basics are posted on my website for all attendees. This lets you specify multiple part sizes that are based on a table without creating a separate family type for each size. The information defined in one family or project using the shared parameter is not automatically applied to another family or project using the same shared parameter. Shared families can only pass (forward) instance based parameters. You know who you are. We had a family that had various nested components that were associated to the parent family by parameters. Note that all of the Types will be initially set to "Yes" (checked). Become proficient in revit architecture design by learning with industry leading expert teachers. The path of the local and central Revit files can now be exported as PDF properties to allow remembering the location of the models from the drawings. I have recently updated my tutorial for nested arrays and formulas which was getting quite old. We now need to set up a remainder width parameter to associate the fixed window width too. ) Go into the Family Types dialog box. Custom Families and Parameters in Revit 2016. Type of Parameter : Area Type: Area Formula: area - required area OK CADclip - REVIT Family Type Catalog Files. txt file will tell Revit® what values to apply to the various Type parameters within each family type so that the family types match the properties in the. Checking Option A un-checks Option B automatically too. Set this to instance; In plan, add a reference plane. Notice the Parameter Types section of this Parameter Properties dialog box (see Figure 8). • Provide a complete list of all Shared Parameters used by Revit on export including ALL properties defined in IFC PropertySet Definition for both Instances and Types. However, we have discovered a slight complication with this. com Revit consists of three types of parameters: Instance, Type (Family or Shared), and Global. By default, the elements of the input that are occupying the same index position are combined together in the node function. Reporting: instance based and can be used to extract value from a geometric condition and report it in a formula or as a schedulable parameter. Hope its clear now. Create a new family from the 'Metric Generic Model' template; Under 'Family Category and Parameters', uncheck 'always vertical' and check 'work plane based' Add a family parameter 'Length'. However, you cannot nest a Shared detail item family in a 3D family. Door leafs, glazing apertures, louvers, ironmongery, door signage & wall closures are fully parameterised avoiding the need for the Revit Family Editor to create or modify doorset types. A good way of having consistent data associated with certain families is to add a nested family with the desired shared parameters into the host manufacturer family you may have downloaded. The course is designed to support delegates interested in building their own 2D and 3D components adhering to best practice industry principles. However, I don't really like that as a final solution. Create family geometry. Once you’ve flexed the model enough and are comfortable it won’t “break”, you can go ahead and create a few family types. X raised to the power of Y = X ^ Y. I am trying to create a family for a client. In order. When family files are updated in Revit 2013, the upgrade elbows out any existing material parameter and replaces it with this. Not really a nice topic, but quite usefull when speaking of Revit Families. Type catalogs allow families to use large (or small) preset data tables to populate the parameter values. I’m going to use a ceiling fan I created and use the blades for the array. HOW TO USE PARAMETERS TO CALCULATE VALUES IN THE FAMILY TYPES DIALOG. We explore formulas, family type parameters, materials, and even dabble in some trigonomic functions. General rule of thumb until recently when using SHARED nested components: Type parameters can be accessed through the project, instance parameters need to be tied to the parent in the Family Editor. Revit usage = exp (x) Circles with pi π. Then add another Calculated Parameter at the beginning - a text type with a formula: "Site Area :" Sort by that parameter before the Site Area, and hide that one too; It puts them on two different lines but at least it removes some repetitive information from the body of the schedule. Revit Nested Family Type Parameter Formula. This mimics what you would have to do in real Revit as well - reading a formula is doable in the project via edit type, setting the formula requires opening the family in th family editor. Now, the family is a line based detail item with a nested generic annotation, containing two types and an instance parameter to indicate a sprinklered or un-sprinklered building. Make sure the With Back option is. This only sets the default value; each instance can be changed to show a different Key Plan type because we made the Label an instance parameter. You have to create your own property by adding new parameter Creating a new family in Revit to perform Family Rotation you have to indicate rotation angle. Creating the nested “tag” is very similar to creating a typical tag family. Take specifically families which have a nested component, and the material parameter in this nested component is linked to a material parameter in the host. To do this, we will create two families, an annotation familiy and a line based familiy. Making this involves clicking New… under Family Types in the Family Types pop up (as seen above). This family was done in Revit 2017. skp) into a Revit family and call it day. Open the original shelf family and save it as the second shelf option. 5 hrs of instructional videos. After you label a nested component as a family type parameter, subsequently loaded families of the same type automatically become interchangeable without any. Change a Type Parameter and all Instances of the that Type will also change. Dicatat oleh Revit. Exceptions InvalidOperationException This is a formula-driven parameter. We will talk about Nested Families and how they can be utilised to cut down on your modelling time. We had a family that had various nested components that were associated to the parent family by parameters. Not really a nice topic, but quite usefull when speaking of Revit Families. This technique uses a nested Detail Item family that has three types: Default, Vertical and Alternate. In this example: the first element; the first parameter name; the first LIST of values. You can't nest them, you can't add them into a family if you haven't already loaded in a family of matching category, you can't control it with a formula, and you can't easily control what they select from or the order that list is in. By default, the elements of the input that are occupying the same index position are combined together in the node function. Anyone who uses Revit know about the built-in Mark and Type Mark parameters.
