Rhino.Inside Revit
1

I’ve tried to create Loadable Family Component with new subcategory but I have still some problems with New Component Family.

When I’ve resolved problem with categoryId: 1. The input category id cannot be assigned as the new category for this family.Parameter name: categoryId.

I get the error 1. ElementId cannot be deleted.Parameter name: elementId

Why the error appear: which elementId cannot be deleted? I cannot understand what I do wrong?
Any help and advise appreciate.

Is the problem the Category <> SubCategory component that is plugged into the Main Family component?

Also, do Generic Annotations support Loadable families?

I will take a look.

Main Family Component you mean all Model categories (not Annotation) like for example Lines?

I’ve tried to use Model categories but I’ve faced problem with categoryId: 1. The input category id cannot be assigned as the new category for this family.Parameter name: categoryId.

I want to create family contains flat triangles with possiblity to assign angles and lenght of the sides of the triangle via shared parameters (please see picture above).

I thought the generic annotations template will be the best choice. If you have any advice of model categories and templates to create flat triangle (lines or surface) I really appreciate.

Normally if I wanted a family to adapt to the Grasshopper shape, I would use an adaptive Family.

Here is an example: Rhino.Inside®.Revit

Is this an existing Family in Revit which you are trying to change?
