I'm testing the waters with topography in revit for structural retaining walls. I have modeled the high and low grade. I cannot get the perimeter boundary of the topography on the high grade to follow the profile of the retaining wall. On the low side of the wall the profile will not follow the concrete stair.

Below are screen shot showing where the point elevations are in plan view and a 3D view of the model.

I am using Revit 2017.

Thanks in advance for any help!

Try placing two points at every location, one on the low grade side of the wall (low number) and one on the high grade side (high number).

Yeah we have to do this quite regularly working from other surveyors DTM, we tend to find Revit creates spikes when inserting ground leveldata and it looks terrible around retaining walls. As WWHub says, you need to place 2 points at adjacent sides of the walls top and bottom levels. You'll likely need to repeat this quite regularly along the length of the walls to stop the topo jumping to other closer points away from the wall. We find that if you reduce the contour distance in site properties down to 500mm the irregularities show much clearer in plan and are easier to spot, edit and adjust.

Hope this helps.

When i do such things such as this, i usually split the surface on both sides of the wall, whether that helps your case or not.
