Feature Script Parameter Bounds driven by another Parameter

bill_schnoebelen

I am trying to bound a parameter based on the input to another parameter. 

For the code below. I want to always make sure Y is less than or equal to X. In another case, I would want Y to be 1/3 X. Is this possible?

If not, is there a TextBox.Change event where I can test?

You can test in the feature body itself, something like:

if (definition.y > definition.x)
    throw regenError("y must not be greater than x", ["y"]);

(passing the parameter y in the second argument to regenError will make it highlight in red if it's out of focus)

You can also do this using Editing Logic if you want the field to change dynamically. See the Spur Gear for an example.

Thanks guys. I think either of those will work. I am going to use the first one for now since it is simpler.
