question on true position dimensions

[john d]

How do I know what workplane to use in pc dmis when dimensioning a true position feature. If I use a x workplane, the true position dimensions a y and z and diameter. If I use a y workplane, the true position dimensions a x and z and a diameter. If I use a z workplane, the true position dimensions a x and y and a diameter. When I use the y workplane, there is no red dimensions, however, when I use the x and z, there is red. What is the secret???

If you are using DCC Features, workplane does not matter, you simply pick the 2 'minor' axis of the feature (the 2 with the smallest vector value). It is only for 'learned' features that you must be aware of the workplane since it wil use what you have active.

Yo also have the check box in the position dialog box for "PERP to Cenrterline" that helps some.
