In-Place Edit fails

[gilsdorf_e]

Hi, I'm struggeling to run a code that works well for parts, but fails when running on an in-place edited part.

Basically it fails when trying to add a sketch with

PartComponentDefinition.Sketches.Add(selectedPlanarFace, false)

The workflow would be that the user starts in-place edit of a part component. Then the Inventor Addin is started and asks the user to pick a face. Based on that selection, it creates a planar sketch on this face.

When run directly for the part component everything works well.
When run in-place, I'm getting the ActiveEditDocument. Casting as PartDocument and reading existing sketches from

PartComponentDefinition works well in Debugging. As soon as I try adding a new PlanarSketch with the selected planar face, it will crash with "Wrong parameter".

I suspect that the selected face is somehow in occurence context, so it cannot be used to create a new sketch.

Any ideas, someone?

When you pick the face in assembly context, it is FaceProxy object (not Face object). In this case you can use 

Dim oFace as Face = selectedPlanarFace.NativeObject

Yesss. I was just going to post that is was a proxy issue. Sometimes it helps writing down you issue. Thank you anyways.
