Hi Tamsin
I have many problems with importing supplied .dwg files, the most common is that I don't know (and nobody seems to be able to tell me) what units have been used, or what scale the file is prepared in, or they were done years ago by a different company that no longer exists. Also, they're often in very old versions of AutoCAD which makes a difference to how they import. So, I get the person supplying to put on a scale bar and scale everything up to this size. I can't remember what I did with this file, but it is certainly the correct size as I have checked the dimensions off the architects supplied drawings.
However, this doesn't happen on most of my projects as I get someone to do my surveys and he gives me a Vectorworks file which is imported in metres (because I know that's what he uses), then I change it to millimetres when I've imported it, and check the accuracy on the scale bar. I'm getting this exact same problem on all my files. I haven't checked whether I get it on a newly created file - which I'll do in a minute.
However, in the meantime, I'm going to revert back to 2021 - I just haven't got time to fiddle about trying to resolve it, I'm super busy and this is really slowing me down. Also, this release seems a bit slower than 2021. I have put in a support request and am waiting to hear back from them.
Thanks for your help.
