Run Thickness Analysis Example (VBA)

This example shows how to run a thickness analysis and generate reports using the SOLIDWORKS Utilities API.




' Preconditions: Substitute the name of your part, which you

'          want to analyze, for xyz.sldprt.


' Postconditions:

'          (1) Thickness analysis report is added to the Design Binder.

'          (2) Thickness analysis report is saved to disk.
