I noticed that the elevations update if you place a product on a wall after you have already drawn the wall elevation. Not sure if this is a "feature"? However, the section did not update even though I have picked the section line running thru the wall/products. Furthermore, I noticed that it also doesn't work after associating a product to a wall that was not originally drawn on any wall. It would be nice to have these automatically update at least when picking the section plane.
