Constraints to relations and pro/program?

[Skiddy]

Im creating relations on my features, to gain full control of my model.

Of which i will hopefully transfer into pro/prog.

My problem is that i would like to add constraints to the relations:

eg
solid extrusion circle radius=5
cut in solid circle, radius from center 2.5 dia of cut =1

I want to be able to control the location of the cut on the circle using pro/prog but obviously if a person creates a radius for the cut at over 5 it will fail.....

How do you put a constraint on pro/prog

eg.
radius number
"please enter radius between 1-5"

can be entered into the relations but no actual constraint is working on the model?

Can constraints be put on relations with out using pro/prog?

Please help?

One way I have found is to write a relation where

if rad>5
rad=5
endif

if rad<1
rad=1
endif
