I'm relatively new to Blender. I'm trying to snap an arch for a door into a face of a building (a cylinder), but everytime I try, it goes sideways. Im'm using snap to face (closest) with "align rotation to target" and "project individual elements". I made the arch from a cube, using the warp tool and haven't rotated the object at all. Btw, sorry for my bad english and thanks for your help.
