I received a question the other day about an unwanted sliver of a toposurface element appearing. At first the assumption was related to Design Options because there was quite a bit going on. Turns out adjusting the pad and its Slope Arrow could resolve the issue. Here's a picture of Pad A and B. Pad "B" obviously has the sliver problem.
Pad A is two pads, one flat and one sloping. Both pads are set at their lowest elevation and the Slope Arrow tells the pad to go UP. Here are the properties of the sloping pad.
And here are the properties of the Slope Arrow for A.
Pad B is also two pads but they are defined a little differently.
Pad B's Slope Arrow properties.
When you need a pad to slope it seems that it is more reliable to define the lowest elevation and work up than in the reverse. At least it helped resolve this sliver.
