I,m experiencing loss of opengl es. and aec generated entities layer control. Aec objects layer dialog indicates the color and linetype designations that I've assigned but actually revert to the default settings in reality. What gives?

I see what you say now ! Indeed on my computer but you must REGEN ALL often. it depends on your graphics card.
BUT the linetype scale don't work fine !!!!!

Thanks for responding. The first problem is the loss of OpenGL ES setting. When I switch to this setting the program starts generating warning notifications (bottom right corner of the program window) and the model window blacks out and the program starts to malfunction until the Open GL medium setting is restored. OpenGL medium setting works just fine, but I lose the last half of the model viewing capabilities. The Open GL ES setting worked flawlessly for several months prior to the current situation. I've tried uninstalling rebooting and reinstalling and even reverting to past versions and still no luck.

You must write to the CMS team with the link in Help menu.
It's weird because you have good graphic cards....

I know man...wtf? Not my only issue either.

To troubleshoot the loss of OpenGL ES functionality and AEC layer control in CMS IntelliCAD,build now gg first ensure your graphics drivers are updated and check that OpenGL ES is enabled in the settings. Try resetting the layer settings to defaults and recreating any AEC objects that are reverting to default settings.
