Get Distance Between Entities Example (VB.NET)

This example shows how to get the minimum and maximum distances between face and edge entities.

'---------------------------------------------------------------------------
' Preconditions:
' 1. Open public_documents\samples\tutorial\multibody\multi_inter.sldprt.
' 2. Open the Immediate window.
' 3. Put your cursor anywhere in the main module in the IDE and press F5.
'
' Postconditions:
' 1. Creates a sketch line that depicts the maximum distance between
'    the face and edge entities.
' 2. Put your cursor over Sketch4 in the FeatureManager design tree and
'    examine the graphics area.
' 3. Examine the Immediate window.
'
' NOTE: Because the part is used elsewhere, do not save changes.
