Determine the Occurrence of a active Sketch in an Assembly

[dg2405]

What is the easies/fastest way to determine the occurrence of an active sketch in an assembly?

My method till now searches alle the leafoccurrences down to the sketch. In big assemblies it takes to long. So is there another way to do this?

Hi, you can return the active object directly:

Dim oSketch As PlanarSketch
If Typeof ThisApplication.ActiveEditObject Is Sketch Then
    oSketch = ThisApplication.ActiveEditObject
    MsgBox(oSketch.Name & " is the active Sketch")
End If

Or do you mean parts? Or sketches from parts?

Thanks for your answer.

I already know how to get access to the active sketch directly. But i want to know the occurrence, where the active sketch is, in the assembly. I need an occurrence for creating a GeometryProxy to project an entity to the active sketch. Everything works fine with my code but it tooks time in large assemblies to find the occurence by searching down all the leaf occurrences.

Here is my Code to project all holes, with same diameter like the selected, to the active sketch. It's a bit cumbersome how i find the occurrence, but it works. I only want to know if there ist an easier way to determine the occurrence.

Well, did you try to get the active-edit object (the sketch) and then it's parent (.parent)?

I'm not sure if it'll return occurrence or document, so you'll have to test it out.
