Get selected sketch segments

[george1985]

Hello,

I selected a line and an arc in my Inventor Sketch.
I would like to get this line and the arc via Inventor API.
How can I do that?

I found a method app.ActiveDocument.GetSelectedObject
But I don't know which inputs to use for it.

I also see that there is app.ActiveDocument.SelectSet.

But when I try to call: app.ActiveDocument.SelectSet.Count, it returns 0.

Can someone help me, how to return the selected line and arc inside Sketch?

I would be very grateful for any kind of help.

Dim s As Object = ThisApplication.CommandManager.Pick(SelectionFilterEnum.kSketchCurveFilter, "PICK")
If s.Type = ObjectTypeEnum.kSketchArcObject  Then
	MsgBox ("Yes")
End If
	

This should work.

Hi @bradeneuropeArthur ,
Thank you very much for the reply.

Is ThisApplication.CommandManager.Pick raising a dialog, which allows selection?

In my case, the sketch segments are already manually selected in Inventor.
I would like to access that already existing selection.
For example, in AutoCAD we can do it via:
Application.DocumentManager.MdiActiveDocument.Editor.GetSelection().Value.GetObjectIds()

But I don't know how to do it in Inventor.

This will do that:

Dim s As SelectSet = ThisDoc.Document.SelectSet

If s.Item(1).Type = ObjectTypeEnum.kSketchArcObject  Then
	MsgBox ("Yes")
End If

Hi @bradeneuropeArthur ,
Thank you very much for the help!
I got an error at "ThisDoc.Document.SelectSet" saying: "Document property does not exist."

I googled a bit, and it seems ThisDoc.Document is an iLogic function. I apologize for not stating at the very beginning, that I am not using iLogic.

Very strangely I tried again app.ActiveDocument.SelectSet.Count, and it returned "2" instead of "0", as initially.
Then I was able to access both sketch segments with your example code: app.ActiveDocument.SelectSet.Item(1)/(2)

Thank you very much for all your help!
