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.
