The process, the software and the commands which you use to convert the mesh to STP file caught my attention.mading wrote: ↑10 Mar 2021, 13:46 Thanks Martan.
This is not a proper reverse engineerined part.
I consider the Quadremesh command as a very useful tool for data compression and for making things easier for the CAM step.
The previous pictures refer to a quad mesh: surfaces approximated by quadrangle mesh.
In a few clicks you can convert the quadrangles into subD or Nurbs surfaces and export the geometry as step files.
Nurbs (and step files) after conversion are far more complicated (huge number of control points).
Yes, everythig hese is solid, starting from the mesh.
My next goal is to reverse these shapes with a limited number of (editable) SubD surfaces.
A note on subdivision surfaces:
https://en.wikipedia.org/wiki/Subdivision_surface
I use CATIA for surface modeling. It is an engineering professional software. But modeling such this organic object isn't very easy to obtain editable surfaces.
Based on my experiences, it is better modeling and surfacing the organic parts using Automatic softwares (like Geomagic and now Rhino), and then split and edit surfaces in professional softwares like CATIA.
I should note that at many times the mesh files which are directly obtained from scanning process, are not suitable for automatic surface modeling due to scanning situation.
Thank you Mading for sharing these info. I'm always interested to know new faster strategies for modeling.
