Rhino-7 Import DWG Problems

Rhino7 seems to have a problem importing nested dwg blocks and xrefs. In other words they are missing from the model import. This happens across various models. My system is Windows 11.
I have re-installed Rhino6 and the AutoCAD import works well - much as expected. However I am now locked out of Rhino7 - unable to re-validate my license key!!!
Whats going on?

Your Rhino 6 is currently locked to a machine named ANNICK, the Rhino 7 needs to added there as well. Or you will need to remove the Rhino 6 validation to be free to add elsewhere.

Note that you want to be on the latest Rhino 6 (6.35)



Thanx - licensing problem now solved.

Any thoughts on the problems I am having importing dwg models into Rhino7? R7 fails pretty badly compared to Rhino6.

We will need more info about the issue you are seeing, there are a lot of improvements to dwg import, including dynamic blocks (WIP only)

Hi John -
This is a known issue which is due to a 3rd party library update. We are looking into our options here…
RH-72439 Open DWG: incorrect blocks in Rhino

Any timeline on solving this problem?
I seem to remember that this started to happen recently. We have reopened a paused project and it all went a bit crazy.
In one case a block that was on the layout of a AutoCAD file appeared in the model space.

Hi Nuno -

I’m afraid not, no. The latest information on this is in RH-72439 Open DWG: incorrect blocks in Rhino.

I suppose you could try to revert to 7.24 where this shouldn’t be an issue.

We had the same issue and went back to 7.23 and it works. Maybe the 7.24 also works.
