Hello Mr. Murat; In this version (8,500) this error has occurred programmatically. These problems will be fixed in a short time and a new intermediate version will be published. Error was logged and fixed. Until the new version comes, you can model over 8.103 exe as a temporary solution and use 8.5 for drawings. In order to keep 8.103
link. In the folder where ideCAD is installed on your computer, change the name of the 'application' to 8.5. Install 8.103, then 8.5 when you open it from the exe named 8.5; In the application that will come as ideCAD Static in the same folder, you will be able to use 8.103. Until the release of 8.501, modeling in this way can be done in 8.103 with analysis, design and drawing with 8.5. Good work.
