Hi everyone, how is it possible to export a patch generated on Matlab in an STL file, in order to be manageable in a CAD environment? Thank you.

Editor's note: Fixed the broken webdocs links.

For legacy versions needing third-party tools, I'd strongly recommend these tools over #22409/#20922. This explains why.

If you use #22409 or #20922 in a modern installation, you will shadow the inbuilt tools and likely cause problems for yourself unless you rename them.
