This is a tough one, I will try to write this so it makes sense ha ha:

I am having trouble with a true position spec - I have a 12mm diameter, with a bolt hole pattern of 3.7mm diameters in a 19.05mm diameter around it. The 12mm diameter is lBl. The back wall of the feature thru which the 12mm & bolt hole pattern diameters are located is lAl.

The true position callout is from each of the (3) 3.7mm diameters, to lBlAl.

In my alignment, the wall lAl is the Y origin, and the 12mm dia lBl is the X origin.

Per the engineers in charge, this callout relates lAl to the diameters as perpendicularity of the axis thru the 3.7mm diameters to the plane that is lAl, rather than a linear distance. It appears, however, that PCDMIS (3.7) is calculating this as linear.

What would I need to do, possibly in the geometry of my constructed features, so that PCDMIS relates, in a TP callout, a line thru the axis of a diameter perpendicular to the plane?

Thanks for any help on this!
