I have Cad data files for analysis. And they have been produced CNC .
Can you exactly describe a file you can use?
My files are 3D surfaced solids like sample,
you can convert these to step from igs
This is a real Keel Beam from The Big B in Seattle
These are flying in the sky.
YOU WILL HAVE TO CREATE SURFACES THEN TO SOLIDs to step to analysys.
I CNC machined this part from this model
