Use an expression in the label style:


SQRT({General Segment Length}^2  + ({General Segment Start Z}-{General Segment End Z})^2)

Jeff's solution is by far the easiest and fastest way in doing this.  I have attached a video on a different method in getting 3D length.  This is how we all learn from each other, right? :smileyhappy:  Here's the link...

Ah equations. Who'd have thought one would ever need math as a draftsman? Funny how it seems that Autodesk is really testing our STEM curriculum these days....

Pythagoras! What would we do without him?

I guess this works for a LINE, or for each segment of a 3D polyline or feature line. But what about the 3D total length of a 3D polyline or feature line?

Credit where credit is due! Give kudos or accept as solution whenever you can.

Until they let us grap the overall starting z and ooverall ending z it ain't gonna happen OOTB. This has been one of my wishlist items.
