I am measuring this part right now this is a cylinder about 3 inches tall. The od is dat-b. The top plane is dat-a and dat-c is a slot in the center of the part. The part has 4 counter bore holes along the side of it every 90 degrees. Here is a picture of what the result looks like, and i know its wrong.
Do i need the od dat to be a cylinder or a circle?
Does it matter if its a constructed cyl or an auto cyl?
My dat c is a constructed width, should it be the line instead?
I have to agree with WolfMan. I prefer legacy, partly for the same reason and partly for a different reason.
I like knowing exactly what is going on with my alignment, because I am directly telling PC-DMIS what to do, but also, Xact and Datum Definition doesn't work well with Datum targets. It's hard to make a primary "plane" when your points are not co-planar and have different vectors.
