Changing DisplaySettings for ComponentOccurence in Assembly - Inventor API

[Anonymous]

I am trying to set the DisplaySettings for a part in an assembly through the API. Right now, I'm getting the selected ComponentOccurence, then from that it's PartDocument, then from that it's DisplaySettings. I then try to change the SolidLinesForHiddenEdges Property for that Occurrence but nothing changes. Do I have to do a refresh of the part or assembly for the changes to take effect? I've tried making the document is driving the display settings and not the application, but that didn't work.

Any suggestions would help, thanks.

Welcome to the Autodesk User's Community..

Programming needs and questions about programming for Inventor should be asked in the Inventor Customization forum for best results.  I will ask the moderator to relocate your posting there.

Thanks, I was looking for an API/Programming forum and didn't see one.

Can you post your code? It's a little difficult to diagnose without seeing it. Also, what environment are you working in? VBA, C#, iLogic?

Hello tdant, 

I'm working in VB.net.

Dim doc As AssemblyDocument = m_inventorApplication.ActiveDocument
Dim selection As SelectSet = doc.SelectSet
For Each selected As Object In selection
	Try
		Dim selectedPart As ComponentOccurrence = CType(selected, ComponentOccurrence)
		Dim partDef As PartComponentDefinition = selectedPart.Definition
		Dim partDoc As PartDocument = partDef.Document
		Dim settings As DisplaySettings = partDoc.DisplaySettings

		settings.SolidLinesForHiddenEdges = True
		settings.DisplaySilhouettes = False

	Catch ex As Exception
		MsgBox(ex.Message)
	End Try
Next

I don't believe Inventor supports what you're trying to do.  I think the display setting that's set for the top-level assembly is used to display everything in the assembly.  If you change the display setting for the assembly to wireframe, everything will display as wireframe.  The display setting defined within any part is ignored.
