When labeling my pipe network, EVERY structure is treated the same. I want to use the same label style for all the structures and let the style decide "what to do".
For example:
- An inlet has a GRATE ELEVATION not a rim. So if the structure is an Inlet, the labe should say "GR: " not "RIM: ".
- A headwall has one (or more) pipe with an invert. But there is no "rim" elevation. There is no SUMP either -- although if the pipe invert is above the ground line at exit, that could be considered the SUMP. But C3D insisted on showing the RIM and SUMP for my HW -- UNTIL I made a new style just for headwall labels.
