Brian Hailey wrote a great paper on Expression for Autodesk University. You might want to check that out.

I think I've found the AU 2009 class you're reffering to:  

"Exploit Expressions to Enhance Your Labels"

I'll check it out.

Thanks!

Brian & c3dreminders, Thanks for all of your help on this. I got it to work using the expressions & 2 text components, one for % & 1 for rise:run labels. The AU class really helped a lot in achieving this!

One thing I noticed is if I go into the "Section Editor" & have my new Link label using the expressions set in my Code Set style for the daylight link, the slopes all display as ???

Not a big deal as I know I can switch to % or rise:run for viewing in Editor, just came to the conclusion the Editor doesn't play nice with Expressions apparently...

Thanks,

Jay
