I have to build a road on sloped terrain, along the path thickness and width both varies, the best way to document those changes would be to make a series of cross sections of the road, the thing is that section marker seems to cut the road only vertically and i don't get the real thickness of all the components on it. I surely miss something as Archicad can show the model in real time with multiple angled cutting sections activated.
I did some tests, and it seems that you have used the roof with vertical edge, right?
Then if you select the roof top and bottom nodes in the 3d doc, it will give you the vertical dimension.
On the other hand, if you select the roof top and bottom edges, it will give you the correct one.
Can you confirm this?
I do confirm that selecting the edges instead of the nodes the quote return effectively the right thickness, I did change the roof edge setting a couple of time to see if it change something: it seems it doesn't. Anyway I post my initial roof settings.
You definitely found what I could have never imagined it would have an effect on the quoting result. Well done. Bravo!
