Perfect AutoCad clone literally

I was surprised to find an identical in most parts program to AutoCad. Who mastered AutoCAD, can continue to operate with ansatzlos CorelCAD. Even all AutoCAD configuration files such as plot styles and drawing standards etc are unhesitatingly and without errors accepted and applied. As far as I'm thrilled.
AAAAB ...
There are very few extensions and plugins available, the developer Gräwert seemingly little need here to see. Most of all I miss the üblichne now even already at Hobby programs stair wall and opening commands.

Because the program itself but stable and runs smoothly and actually the attribute 'professionally' earned (color pen tables, for example) I forgive 5 Stars. However, the expandability bekämme only 3 stars (because, after all, many AutoCAD Resourssen lassen- use directly otherwise it would be really zero!)
