Sorry for the sort-of cross-post. I didn’t see the Feature Request subcategory until after posting to the general Layout category.
I think it would be much more useful if dimensions would not snap to the softened edges of facets of curved surfaces. Because the program will snap to softened edges as readily as hard, it’s extremely difficult to accurately dimension extruded curves like architectural moldings. In full scale sections, it’s fine, but if I have a countertop with a 1-1/2" thick bullnose edge and need to show in a half-inch scale elevation that it is 36" off the finished floor, trying to pick the actual edge of the bullnose counter can be extremely difficult, and sometimes impossible, because Layout instead snaps to invisible facet edges of the curved surface, which are extremely close together as the curve recedes. It’ll snap to 35 15/16", or 35 7/8", etc. And there is no way to see which edge is selected (zooming in doesn’t help past a point because the lines get wider than they are apart), and no way to know if the dimension is correct unless you already know what the dimension is supposed to be. Which sort of defeats the purpose of scale modeling, doesn’t it?
There may be another way to accomplish the same thing, but I really don’t know what use it is for dimensions to snap to soft edges. Curved surfaces don’t actually have facets in the real world, so there would be no reason to dimension them in a drawing.
