As the title says.
Why can’t Rhino windows open *.usd…?
Hi Martin -
I’m not sure if this is really a “why?” question rather than a request for having that possibility…
The request is on the list as RH-78662 create import for USD
As for the why, perhaps this works for you?

Thanks for the information. I’m asking because @mkarimi seemed surprised I cannot import *.usdz but he can on Rhino mac.
Windows:
Mac:
I’m using iRhino to look at *.usdz exports but importing back into Rhino windows could help verify what is exported.
Or can you suggest a good online viewer?
Hi Martin -
Yes, USD import was developed for iRhino on iOS and was somewhat accidentally included in the Rhino for macOS version of Rhino 8.
I’m afraid I don’t use online viewers and can’t suggest which one is “good”…
-wim
nice 
If the code exists for Mac, is it a big deal to incorporate it for windows?

This assumes the export/import are equal in functionality, which currently they’re not and may never be entirely.
I use usdview most of the time usdview Quickstart — Omniverse USD.

Our USD Import/Export is open source. When I merge it in it’ll be cross platform.

That’s a good point.
I’ll try Omniverse again…
I accidentally added the one for Mac when adding support for USD on iRhino in order to get some of the room scanning stuff working. The version I wrote uses operating system specific libraries and is not cross platform. What Callum is working on is cross platform and will be part of both the Windows and Mac installs.

Thanks for the information. Looking forward to having this implemented.
