Bobbyv33,
I can respond to most of the issues you raised.
You said: "I can't dimension an arc. The only way I can do it is to draw the complete circle, dimension it and then delete it."
We expect this to be fixed for VW 9.0.1.
You said: "When I try to dimension using any part of a circle, (top left side etc.) it always snaps to the center."
We expect this to be fixed for VW 9.0.1.
You said, "When I copy from one drawing to the other, dimensions always go to the wrong class."
We expect this to be fixed for VW 9.0.1.
You said, "The center mark tool, even though it is drawn in the right class, has the wrong attributes (line weight and color)"
I looked at this, and it seemed to work for me. If you can duplicate this, then immediately after you place a center mark that is given the wrong attributes, please save the file and send a copy of it to me with an explanation of what you think is wrong.
Thanks,
