Coreldraw and CorelCad are presented as compatible. You can import a Coreldraw figure in CorelCad, but you simply cannot use it if this is not a simple polygone (import errors). It doesn't matter how the figure is generated.
Would make editing fills and strokes less repetitive. I use CDraw to refine XML music prints. Selecting object by object is so slow. Even that could be improved if you could just find the next object with a keystroke.
