Run Interference Detection Example (VBA)

This example shows how to run interference detection on an assembly.

' Preconditions:
'    1. Open <SolidWorks_install_dir>\samples\tutorial\advdrawings\bowl and chute.sldasm.
'    2. Open an Immediate Window.
' Postconditions:
'    Inspect the Immediate Window for interference information.

' NOTE: Because the assembly is used in SolidWorks tutorials, do not save any changes to it.
Option Explicit

Sub main()

Dim swApp As SldWorks.SldWorks
Dim swModelDoc As SldWorks.ModelDoc2
Dim swAssemblyDoc As SldWorks.AssemblyDoc
Dim pIntMgr As SldWorks.InterferenceDetectionMgr
Dim vInts As Variant

Set swApp = Application.SldWorks
Set swModelDoc = swApp.ActiveDoc
Set swAssemblyDoc = swModelDoc
Set pIntMgr = swAssemblyDoc.InterferenceDetectionManager

' Specify the interference detection settings and options

pIntMgr.MakeInterferingPartsTransparent = False

pIntMgr.IgnoreHiddenBodies = True
pIntMgr.ShowIgnoredInterferences = False

'Specify how to display non-interfering components
pIntMgr.NonInterferingComponentDisplay = swNonInterferingComponentDisplay_Wireframe

' Run interference detection
vInts = pIntMgr.GetInterferences
Debug.Print "# of interferences in 1st run: " & pIntMgr.GetInterferenceCount

' Ignore an interference
vInts(0).Ignore = True

' Run interference detection again (should detect one less interference)
vInts = pIntMgr.GetInterferences
Debug.Print "# of interferences after one is ignored: " & pIntMgr.GetInterferenceCount
Debug.Print ""

Dim i As Long
Dim j As Long
