Revert STL file to solid

Have questions or comments about Simplify3D, Slic3r, Cura, Reptier, etc? Or wondering about which CAD software to use...discuss it here...

Revert STL file to solid

Postby jferguson » Wed Jan 31, 2018 3:26 pm

I've discovered that some STL files can be reverted to STEP files (solids) which can then be imported into a solid modeling application, Creo in my case, and modified in some ways.
I used FreeCAD which i run on Ubuntu 16.04. I import an STL file into a FreeCAD session, run the mesh analyzer, auto-repair any problems found, convert to a shape, then to a solid and output a STEP file.

Then open the STEP file in Creo, and it's not paramtetric, but you can drill holes and add and subtract material from the solid.

I also tried reverting some STL files used for fuselage sections in a 3dlabprint.com r/c plane but, alas, these files, despite printing well after slicing in Simplify3d had too many problems to convert.
