I’m trying to drive a dimension with an equation that increments the value by .3125.

If a user types in .350 the equation will increment to .625 and if the user types in .626 it increments again to .9375 and so on.

Does anyone have an equation to make the dimension value jump in .3125 increments?

Thanks,

Ken

Your immediate problem seems to be with your arithmatic.

I don't think Excel offers a function which replaces itself. I think that is a new concept in maths.

What about a Design Table (or a redundant sketch element if design tables don't work with sketches) where the user types in a value and the sketch element is dimensioned by a calculated value.
