Details

Published: 04 November 2010

This is a demo movie of an Catia VBA application that gets the links in Catia V5 part, assembly or drawing

The size of this movie is about 12Mb so be patient ...

<VB Code that reads Catia V5 Edit->Links Command and provide the content of the
window to be used as needed by the user.
