In a recent post about Ramps (and their problems), I stated that you cannot place Spot Elevations on the sloping part of the Ramp. While this is true in plan views, I was surprised to discover that Ramps can actually be annotated in 3D views…
While working with shape-edited Floors, I have noticed that you cannot place a Spot Elevation on a sloped Floor face with a curved edge. You can place Spot Elevations along any edge, but once you hover over the actual face, it won’t allow you to place a Spot Elevation.
The Spot Slope can be a useful little tool out in the landscape. You can place one at any given point and immediately get the slope for that face. But they do have a few funny little quirks as well as some other limitations.
As I’ve mentioned before, Topo is difficult to modify and fine-tune accurately. It is not impossible, though it can be time consuming. But understanding how Topo works and triangulates can make this task manageable and much less frustrating.
To start off, I have created a Toposurface with the following contour lines (though I actually used Topo From Lines, to make this one).
