How to install the add-on to import Rhino .3dm files This question/answer seems exactly what I need.
Import/Export Rhino&#39;s 3DM format to/from blender
But I tried installing import_3dm-master.zip as it suggests, and the rhino3dm-master.zip on which it seems to depend (downloaded zips from GitHub) and don't see a new import format on the File-&gt;Import list.
What simple, obvious thing am I missing?
(And I can't just add a comment to that thread because I just signed up and apparently need a 50 to comment. Hmmm.)
Don't download the master branch, instead download the latest release here or use the following links to download directly.
Windows: https://github.com/jesterKing/import_3dm/releases/download/0.0.8/import_3dm-v0.0.8.win.zip
Macos: https://github.com/jesterKing/import_3dm/releases/download/0.0.8/import_3dm-v0.0.8.macos.zip
Then install the same way as any other addon. Hope this helps!
