Feature line relative to surface

[cadtag]

I've got a bunch of feature lines that were created with their start elevations relative to a surface. That surface has been replaced/updated, is there a way to force the feature lines to reset them selves based on the current surface? Example originally started at 50.16, current surface elev at that point is now 50.58

Or do I need to delete and replace them all?

Setting entire Feature Lines relative to a new Surface is easy, but if you're only setting individual points relative, the only way I know to do so without redoing each point one by one, is to map the old Surface to the new Surface (AeccManageDataShortcuts).

Without setting something up to test it here, that *should* update the points that were set relative to same.

Yea, that's part of what's weird -- it's actually the same surface, from the same source file that's dreffed in. I'll swear it used to work and update the initial points that were set relative to the surface, but rebuilding the source surface from scratch seems to have fubared it somehow. Fun and games with paving paradise...

You can if course drape them onto the surface again, or to keep everything relative use the MOVE command. Pick any point then for displacement use 0,0,0.42 to raise them.

the difference varies, so I'm back to the first option
