Engraving the contour from assembly


New member
Hi everyone! I'm using Creo 2.0 M250. Here is my problem:
I have too many sheet metal assemblies from different sheet metal parts. For each assembly I should make a drawing with all dimensions that are needed to perform a welding. It takes too much time. Instead of making drawings I want to give the information about position of, for example, smaller part on the surface of the bigger part with the help of engraving (our laser machine can do this). Both parts has, for example, cylindrical or curvilinear surface.
What is best way to get the contour of smaller part on surface of the bigger part in flat state?
