Hi @nathanletwory , just stumbled across your Blender 3dm importer video via Luis’s tweet and I’m completely blown away! This seems to be the link that I wished to have for years now.. Did the transport via FBX and OBJ until now but it always was some kind of a hassle. Do you plan on extending that…

whoops. stupid questions… thanks for the repies… im looking forward to bring linedrawings from rhino to blender could be the alternative to acad to 3dsmax workflow.

Nathan, I just pushed a new branch that adds in basic unit handling on import. The three options are: Ignore - “default” Assume the user knows what they are doing (working as before no change) Convert Rhino - Convert the incoming rhino file into the current Blender unit system (working somewhat) …

[image] joel_putnam: I have posted over in the Blender Discord I assume you mean blenderartists.org ? I couldn’t find the topic for this. A link perhaps? For the unit system conversions you’ll end up only scaling really. Since all Rhino objects are effectively at world (0,0,0) you should just…

No the dev talk similar to this channel here for Rhino [image] nathanletwory: For the unit system conversions you’ll end up only scaling really. Since all Rhino objects are effectively at world (0,0,0) you should just apply the scale transformation with (0,0,0) as the scale center. Once done y…

Ah, hmm. I think we need to create our own context here so we can set the necessary bits and pieces so that the transform_apply works. That way you don’t have to do select_all, which can be dangerous if you’re importing into a file that has already geometry. edit: a quick look in Blender source co…

Cool. I made some small comments on your new branch. Most important is to remember to sync your fork with upstream.

ok that was “fun” :crazy_face: I have issued a pull request to handle incoming units as well as conversions between Blender/Rhino should the user require that. Joel

I’ll be testing your changes properly tomorrow. Just reading it mostly looks good. Some things that stand out are for instance the meters to micrometers, millimeters, centimeters and kilometers looking funny, I’m guessing result of copy&paste: here

okay I have FINALLY switched to the new Open Nurbs unit conversion function.

if u_converter:
bpy.ops.object.transform_apply({‘selected_editable_objects’: toplayer.all_objects},location=False, rotation=False, scale=True)

Thanks! That did it
