Querying Elements by Subcategory in Rhino.Inside.Revit Grasshopper

Bryan_Rincon · June 8, 2023, 4:11pm

In Rhino.Inside.Revit Grashopper, is there a way to choose Elements by Subcategory?
For Example, I have bunch of Model Lines I’ve sorted by Line Style.

Is there a way to select or identify only the Lines with that specific subcategory (Line Style) once I bring them in?

Hi,

There is no dedicated component for this, but you can build your own using a cluster like this one.

Hi Kike, is there a way to get access to the Subcategories in Detail Item from a project file? For instance, get which family types are using one selected Detail Item Subcategories. I tried connect the “Element Subcategory” with an detail item instance, it returns “null”.

Hi Hali,

Detail items are View dependent, try something like this…

Hi @Japhy,

I have also same question.
What “Element Subcategory” component uses for?
I see we can use Element Geometry component to get the geometries of subcategory…

I am just trying to find out the usecases using “Element Subcategory” component. Cannot come up with the ideas as the output of Subcategory is Null…

If you can get/set the subcategory if available.

mcneel/rhino.inside-revit/blob/1.x/src/RhinoInside.Revit.GH/Components/Element/ElementSubcategory.cs

using System;
using Grasshopper.Kernel;

namespace RhinoInside.Revit.GH.Components.Elements
{
  [ComponentVersion(introduced: "1.8")]
  public class ElementSubcategory : TransactionalChainComponent
  {
    public override Guid ComponentGuid => new Guid("495330DB-5733-4718-ADBB-73C2FB5787A7");
    public override GH_Exposure Exposure => GH_Exposure.secondary | GH_Exposure.obscure;
    protected override string IconTag => "SC";

    public ElementSubcategory()
    : base
    (
      "Element Subcategory",
      "Subcategory",
      "Element Subcategory Property. Get-Set access component to Element Subcategory property.",
      "Revit",
      "Element"
