Generic Model - Frame Cut Back

[MartinGTE]

Hi all.  Happy New Year,

I am messing about with a generic family for a frame.  I have inserted a structural column & framing family to create this very crude frame to experiment with.  I have got it flexing fine and its working well.  However when I place it in a project the beams are 'cutting back' when I don't want them.  

Couple of images. One from in the family is how I want it to look.  The other when in the project.  All parameters are the same.  I haven't changed anything.

Any ideas how to stop this?

This seems to be a common question when nesting Structural Framing Elements into families and unfortunately this is the known behaviour of structural members when nested inside other families.

Either place them directly in projects and use Groups or crate Beam Type Families created based on Generic Templates and not Structural Templates, then change the Category to Structural.

In your scenario you would need to edit the Structural Framing Family and change the end references to remove the Cutbacks and load into your Generic Family/Frame

If you share the family file, I or someone else may be able to help you fix it directly, rather than relying on speculation based on an image. However, if you'd like to experiment on your own, the following tips should set you on the right track:

1. Framing Templates:
   There are two types of framing templates in Revit:

   • Beams & Braces Template: This template requires specific predefined measures to work correctly.
   • Complex & Trusses Template: This is a more flexible and user-friendly option. Alternatively, you can model beams as Generic Models and then switch their category to Structural Framing for more versatility.

2. Using the Beams & Braces Template:
   If you use beams created with the Beams & Braces template, ensure the following:

   • Shared Family: Make the family shared to control geometric constraints and behavior within the model effectively.
   • Material Behavior: Assign the appropriate material to/in the beam family (e.g., wood, concrete, steel). Different materials behave differently when loading into the model—some cut back automatically, while others don’t. Use this behavior to your advantage when designing.

On the same topic: Another user, @HaniTartour  raised a similar question about when to use each of these templates and this discussion is one example where and when to use which. For more details, refer to their post (link below)...or maybe he can refer to this

Additional Tip: 

The same applies to the column family. There are two different approaches to this workflow:

1. Both Beam and Column Nested into a Parent Family:

   • Both the beam and the column are loaded into a host/parent family as shared components.
   • In this case, both the column and the beams are based on the Generic Structural Template.

2. Nested Relationships:

   • Beam Nested into Column: The column drives placement & uses the Structural Column.rft Template, while the beam uses the Generic Structural Template.
   • Column Nested into Beam: The beam drives placement & uses the Beams and Braces.rtf Template, while the column uses the Generic Structural Template.

Additionally, there is the adaptive components approach, where both the beam and the column are nested into an Adaptive Components Template.
