Why is it that spot elevations on a toposurface will sometimes snap to a particular point (with a small cross showing when that happens), but other times it does not? I have hundreds of elevations on my toposurface all around sidewalks, curbs, etc., yet I encounter these "snapping" points seemingly at random. It's very annoying when a spot elevation anywhere within 12" or so of that point will ONLY snap to that point and nothing else. When I'm trying to indicate top and bottoms of curbs (points very close together) this really gets problematic.
As an example, I have a curb going around a peninsula along a row of parking. I have a total of 12 points in the toposurface around that end (3 points for each curve, with a set for the top of the curb and another set for the bottom of curb). But only 1 point out of all 12 has that snap problem. I would prefer none of them did that.
Anyone encounter this? If I try to "nudge" a spot dimension w/ the arrow keys, and it gets within the "snap" boundary, it jumps to that snap point and I cannot move it away with the arrow keys. So annoying!
