I am tired of importing from Archicad into Twinmotion and having some of the elements in my model completely displaced.. it's a huge hassle because moving objects and surfaces around in Twinmotion is not an easy undertaking and it has no precision whatsoever. This problem only happens sometimes: More often than not. And has happened with various versions of Archicad and Twinmotion. Currently I am running ArchiCad26 and Twinmotion 2023.1.0
Twinmotion 2023.1 is still in preview version, so there are some bugs. I would say that the best option is to use 2022.2.3 but the new plugin for AC26 can't export to TM 2022.2.3. So at the moment it's really a mess. I was able to export SKP from AC26 and import that into TM 2022, but it didn't work when I tried the same method with another project.
You can export a Rhino file from AC26, open it in Rhino and then sync with TM. But of course this is a very cumbersome method.
I would recommend you to go to the Twinmotion forum and report a bug about this issue. It's affecting a lot of people (including me) and it's been months.
Here's the link for the forum . There's a contact us button on the right.
