Create pattern on ramp

[joris.vanbossche]

For construction reasons I want to have a pattern on ramps so I can place coordinates on them.
As you well know it’s not possible to place a spot elevation on ramps:

So I want to create a projection of grids of lines on this ramp so that on the crossing of each line I can place a spot elevation:

At the end I want something like this (what we did in the past manually):

But I have no idea how to start on this

Try the Lunchbox custom package. Use the Divide Surface node. That will give you the points you need in a standard rectangular grid pattern.

Your problem is that Revit can’t read elevation from ramp in view. If you manage to place elevation tags on grids, Revit still won’t able to read height from them.
Try modeling your ramp as floor or any other family.
