Hi,

I only recently started working with the SolidWorks API. Now I'm trying to change the material and appearance of a few parts in an assembly. I figured the easiest (for me that is) way to do this, is by opening the parts in the background and then changing the things I want to change. But everytime I run the macro, I still see parts opening.

I narrowed what I have down to this:

Sub main()

    Dim swApp       As SldWorks.SldWorks

    Dim Part             As SldWorks.ModelDoc2

    Dim longstatus  As Long, longwarning As Long

    Dim boolstatus  As Boolean

    Dim macrfolder  As String

    Dim Materiaal   As String

    Set swApp = Application.SldWorks

    macrofolder = swApp.GetCurrentMacroPathFolder() & "\"

    Materiaal = "Pure Gold"

    swApp.DocumentVisible False, swDocPART

    Set Part = swApp.OpenDoc6("schaar_onder.SLDPRT", swDocPART, swOpenDocOptions_Silent, "", longstatus, longwarning)

    Set Part = swApp.ActivateDoc2("schaar_onder", True, longstatus)

    Part.SetMaterialPropertyName2 "Default", "C:/Program Files/SOLIDWORKS Corp/SOLIDWORKS/lang/english/sldmaterials/SOLIDWORKS Materials.sldmat", Materiaal

    swApp.DocumentVisible True, swDocPART

    swApp.CloseDoc "schaar_onder"

End Sub
