Re: Regen error

Apparently, your system has graphics device issues.
Are you using a system with 2 graphics devices? make sure to associate a suitable one with CMS IntelliCAD; Nvidia GeForce cards are recommended.

Make sure that you're running the latest build of CMS IntelliCAD 10 (check that at the HELP menu) and also that you use a suitable graphics device with CMS IntelliCAD.
Also, tweak the graphics setting using GRAPHICSCONFIG command.
