In all the PTC/CREO suport materials, are there examples of using Excel's VBA to drive repetative operations in CREO? Thank you.
When you say "repetitive operations" what are you referring to?
You can use Excel to drive geometry:

You can also use VBA to interact with the VB Toolkit. This can be complicated to setup and is not entirely user friendly.

Alternatively you can record a mapkey and then edit the mapkey to suit your needs.
