Label Expressions as Design Tools for Vertical Curves

A few weeks ago I wrote about how I use References and Expressions to assist with intersection design. Here is another label I use that is helpful. I certain jurisdictions where I help do work, there is a rule of thumb that says vertical curves should be approximately 25' long for each 1% change in grade. So I made a little design label part of my profile label set that contains this expression: When I am done I can either freeze the layer, change the label set, or just ignore them if I have them setup on a no plot layer. This is only the beginning. Expressions and References are a great tool- try them.
