It appears that you can't redefine datums anymore?
For example, if I have a DATDEF C, PLANE_C it seems I cannot redefine that to another feature, like DATDEF C, CIR_1. PC-DMIS pops a dialog stating that the name must be unique (referring to "C" in this case).
For me, this is a shortcoming since we can have a 100 holes with weldnuts which all have a concentricity on the weldnuts in relation the holes (all referring to the same datum, but the datum is the hole where the weldnut is located) so we redefined the datum for every hole. This seems not to be possible anymore?
As far as I know, FCF datums can use 2 digits, within limits. Datum C1, C2 etc. Since you appear to want to create a pattern of sorts, and will use more than 10 datum C features,, you're probably better off using legacy dimensions.
