Get Cosmetic Threads Features in a Part Document (VBA)

This example shows how to get cosmetic thread features, mirrored and patterned, in a part document.


' --------------------------------------------------------------------------


' Preconditions: Part document is open and contains mirrored

'                and patterned cosmetic thread features.


' Postconditions: None
