Creating Silkscreen from 3D Model Data

Mike Kanigan's work flow for creating silkscreen for complex parts using 3D models.
 
Start with a blank PCB, place the step model, create a board line using a surface of the step file "Board Shape -> Define from 3D Body" feature

Create Primitives From Board Shape -> Change layer to Top Overlay. Copy the new silkscreen outline to the PCBLIB part.

And there you have it!

The nice thing about doing it this way is that it also places pads and PCB cutouts!

I have also used this same technique to generate keepouts from step file enclosures that I then turn into silkscreen so its visible on the PCB.
