Adding 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?

You could add these relations:



if radius<1

radius=1

endif



if radius>5

radius=5

endif



This will constrain radius to stay between 1 & 5...

You can also write If Then Else statements within the input section of Pro/Program. I've never tried to use this to check the validity of a response, but you might want to try it.
