Can you provide us with an example of what you're trying to do? It doesn't have to be the real part, just something with Expressions which are failing.
Thanks for the reply!
It's a rectangle shape constrained with a vertical and a horizontal dimension. I want the expression to cause the horizontal dimension to change so as to maintain the area of the rectangle if the vertical dimension is modified.
I'm thinking of using a Simple Distance measurement of the horizontal parameter in the expression, in place of the horizontal dimension so as to avoid a circular reference.
May be I dont understand...
Set expression S=1000
Create Scketch with H dimension (any value) and L=S/H
If you will change H - > L will be changed too, keep S constant....
