Hi Michael,
with the new beta v4 on Mac i have several Errors with the script from your link..



BUT:

i just wrote a VERY quick and dirty plugin script with Karstens (KMRQUS) Nodeeditor Code to import STL files into Moi..

So far it works...

I totally agree with you that its not a good idea to work with this in Moi! But often i get a STL file for 3D printing which needs a little tweak. Than i import the STL (until now i used FreeCad for converting it but Karstens import Node does the job much more faster) and than i rebuild it as a real NURBS solid in MoI with the help of the imported edges and dimensions. Its still a lot of handwork but it works fine for me...

Perhaps someone like to add some time for a nice and usefull STL import script...
