OK, then maybe I have the wrong expectations on this. In two other programs that I have used (ViaCAD and Alibre Design), the grid did not project through the object all the time. If the part were 3 units high on the Z axis, you could see it extend up above the grid and would not see the grid through it. If you looked at the part from the -Z side, you would see the grid overlayed on the part. It would therefore be very obvious about whether the part was "above or below" the grid or even intersecting with it. Does that make sense?
I am expecting TC to do something it does not do?
One reason I ask is that I am looking to upgrade and am trying to decide between several different applications.
Thanks for the help!
