I am experiencing error on my sheetmetal 3d drawings on 3 AMD machines (3700X, 2700, 2500U) I have contact the application support and it does not have issue on their end. More on this at: Not getting desired value with constraint features - General Discussion - IronCAD Community . I don't have any intel based machine i to try if is a platform issue. the 3700x and 2500U runs W10 2004 while the 2700 runs on W10 1909. My work is getting messed up never had this problem before on this project.
If you can post one of your computer specs including GPUs being used might be helpful.
It could be a GPU driver issue.
Version of Iron CAD you are using.
Thanks for your reply and apologies for not getting back soon.

Used to have a WX4100 on the main pc and WX3100 on the back up pc. Cursor/hour glass intermittently disappears while saving that led to change.
Thanks for the computer info
Hopefully another User with IRON CAD experience can either verify or say something different as far as results go.
Since you are using 2 different types of GPUs it does indicate it is not a GPU card specific issue but could be an AMD Driver which is compatible with all two GPU cards.
Latest APU and RX5500 AMD Driver: https://www.amd.com/en/support/kb/release-notes/rn-rad-win-20-5-1
See if you can borrow an Nvidia GPU card and see if the same thing occurs. That would eliminate AMD GPUs and its drivers as causing the problem.
Make sure you use DDU in Safe Mode with Internet disconnected to remove all traces of AMD driver before installing Nvidia GPU driver and vice versa for installing AMD drivers.
But from reading the link you posted at Iron CAD Community it seems to be an Iron CAD issue rather than anything else.
Personally, I don't believe a Driver will affect how Data is shown in a software like it is showing in Iron CAD. That seems to be an internal bug of Iron CAD.
Or Iron CAD is not 100% compatible with another software you have installed on all three computers.
Try running Windows in a Clean Desktop (eliminates 3rd party apps) and then run Iron CAD and see if the same bug occurs. If it does occur that eliminates 3rd party interference with Iron CAD.

EDIT: Plus you are using three different AMD Processors with the same results. Unless Iron CAD needs a special Intel Processor instructions that AMD Processors don't have.
