I'm trying to develop my use of Freecad Path for cnc 3D milling. I have been doing a lot reading regarding file formats. To make a long story short, I have been concentrating on converting mesh files for milling. I'm pretty comfortable with milling shapes I designed in Freecad CAD. My understanding to date is that a Mesh has to be reduced to number of triangles in the neighborhood of 50,000. then converted to a solid making sure the geometry is closed. Then exported as a STEP file. Then brought back into Freecad by opening (not importing, takes forever).
When I do this the geometry is seen in "Setup" but when I choose "Surface 3D mill" it doesn't see it. Needless to say I have been over this at least a 100 times. By reducing the facets to 12,500 it made a big difference in getting the file to open up. However no luck in developing a too path.
Any help would be greatly appreciated.
Tried to attach it but still says the STEP file is too big.
Thanks

Re: STEP file not visible geometry in Path
Hi, doesn't exactly answer your question, but this is what I do when creating path jobs from (for instance) STL mesh files.. Might be something useful in there?

Re: STEP file not visible geometry in Path
I have the same problem, the STL files have been generated in Catia V5 (CGM) and cylinders have two halves (seams). If you want I can upload here a file.
