Import_3dm Rhino file is tiny in Blender

[Akash]

Exporting the Rhino file to Blender with Import_3dm, works great.
Only that there’s a ‘lost in translation’ scaling issue [even though the size (40mm) and world location (000) shows correctly in Blender.
first I thought only the outliner’s data came through… but model just came in from Rhino very very small [in screen space]. Blender’s version of Zoom_Extent Brought the model in, and I’t been ok for texturing, but trying to render, the model is back to a 1pixel grain of dust far far away…

Searching Blender info… I saw a post referring to clamping size in OBJ import… but there is no clamping option in the Import_3dm…? any idea how to fix this.
I’m only using Blender for rendering, and knows only tiny bit of it at this time. All the molding is in Rhino.

In ZB there’s a button to unify object scale to a size the app is comfortable working with, without changing its actual world scale… but I can’t seems to find a reference to a similar function?

thanks a lot

Well, move the camera closer to the object! If it’s the default camera, it’s located so that it centers on the default blender cube, which - IIRC - is a 1x1x1 meter cube. So yes, a 40x40x40mm cube will be a small speck. Just navigate the camera closer, and you should be good to go. So it’s not your model that is small, it’s the camera that’s far away - that’s how 3D works

Apology for the newbe questions, I only went to blender to render… knowing very little of it.
I find it confusing that even as I set units to mm before importing, everything still stays in the large global scale of default
Moved the camera to a 100mm from origin, it was very large so scaled the camera to 0.1, but that leads to other problem, can’t zoom in past screen size of like 10mm.

Can’t recall ever needing to manually move the camera in Rhino… but then I never really rendered in rhino…

thanks a lot

With the camera very near… this looks like something with the import.
I have exports a part of this model out [to Painter and back] and it came back in the correct size! about an order of magnitude larger than the remaining parts from the Import_3dm.
for now to get on with the rendering, guess scaling the model 10x or so will hopefully make it renderable.
