Pretty sure you CAN NOT take a PROJECT or DRAWING configuration into a SYSTEM configuration.
There are PROJECT Option configurations that I have very little grasp on so I refuse to use them, I leave as DEFAULT, I think a tutorial on these is very important (maybe already available not sure)
Mitigation needs to be flawless with ZERO risk between releases to keep users from shying away and getting frustrated.
I also lost all my custom walls somehow but after using ARCHIVE BACKUP/RESTORE a few times i recovered them. I'm sure i've lost other settings but wont be aware until I actually start using 2022 daily...still finishing 2020 projects now. i refuse to pull projects from 2020 into 2022 out of fear of the above issues.
Years ago i was part of a SAP business software mitigation into our company, I assure you the Softplan growing pains are minimal by comparison. SAP implementation was a total disaster and took forever to get on track.
Would it work if you loaded a project from 2020 into 2022 and save that??
