Square slot used as [B] and [C]

[NBO CMM]

Datum [A] is a plane, Datum [B} is the length of a slot and [C] is the width of the same slot. How can I get PC-DMIS to give me (M) on [B] and [C] for a profile callout where the datum shift would affect the results.

Don't create a slot and create 2 WIDTH FEATURES instead ?

Can you show me some example code of this?

If you use a width as a secondary or tertiary datum aren't you using a centerplane and not a feature of size?

Widths are features of size. See my example below...

2.4995 is the nominal size of WIDTH1. This size is only relevant along the appropriate axis!! (X in this case).

You can also use different algorithms for widths regardless of which algorithms were used on the features they are constructed from. If you construct a MINCIRC width from 2 LSQ planes, it will calculate correctly from the hits of the 2 LSQ planes.

Beat me to it.
