sorry for my question which to many may seem stupid and trivial!
I've found at a site (GrabCAD) some files that I was interested and completely free for my personal project (small project model)! the problem arises here. I use Inventor Fusion, nothing to do with solidworks! But I can not import the file. sldprt! and the only way is to convert them to import STEP files.
For days and days I'm looking for a solution to be able to solve this problem, with converters compatible programs, you are my last hope!
I saw the prices of solidworks, and are not accessible to me.
I would ask if someone willing could re-save me these files, they are about 13, but a few kb are heavy!
