Hi
I have come across a serious problem in Revit.
When I attach a wall to a roof and make adjustments in wall- and roof structure so the wall extend up in the roof construction one would think that the wall actually gets higher. This is however not the case. The extending of the wall is only 2D. This makes the calculation of area wrong, and you can not export the 3D model to a manufacturer for precise wall manufacturing.
See screnshot. (3D view. Roof is transparent and a section box is applied)
Best regards
