Hi, Apologies if this is not the right forum.
This is a bit of a bug report, I have just run this through a couple of times and I think I can see where the issue is.
This is in 26 solo on a MacBook Pro 2017
We were updating our basic template and after a recent revision they have become corrupted; we are unable to open them. When trying to start a new project with the corrupted template we get the attached error message.
I ran through all the amendments we made and it seems to occur due to the publisher sets
To trigger it;
I think the 'merging to one dwg' of subsets creates a problem. I have tried different ways to provoke this and it always seems to occur when I try to save a template with a publisher subset item that has 'merge to one DWG' activated, even if the subset contains only two layouts for instance.
Anyway, interested to see if this occurs for anyone else.
Have you reported this to your tech support contact for your country? And, Archicad otherwise works normally (other files open fine)?
It happened to another file, but I didn't make the connection then and can not be sure.
Everything else works very well.
Just a hunch but try removing the exclamation marks (!!) in the DWG names.
