Expression for LinkLength

[Lisa_Pohlmeyer]

I'm trying to create an expression to label a LinkLength in my section view.  I only want the label to show if the LinkLength is greater than zero.  Our subassembly for a ditch bottom width targets a polyline, and the label style dimensions correctly, however, of we choose to use a V bottom ditch in that area by setting the link width to 0, the label style shows 0.  I'd like to set it up to not show at all if the width is set to 0.  See attached pic.  My current label style has line components, but I can certainly change that if required.

You could create an expression that checks the value of the width and returns the link width if it is greater than zero otherwise it returns -1. Your label content would then be set to not hide negative values. Expression - if({Link Length}>0,{Link Length},-1)

Perfect! Thanks. I was trying to just put a space instead of a value, like you can in Excel. I didn't think of your option.
