Drawing Custom Ceilings and Sloped Slabs
This page has two tutorials about ceilings in Plan7Architect. The first video, about four minutes long, shows how to draw custom ceilings. Ceilings in a building model are also referred to as ceiling slabs or floor slabs, since they form the floor of the level above.
The second video is a short tutorial on drawing a sloped slab, also called an inclined slab, slanted ceiling or sloping ceiling. Plan7Architect works in 2D and 3D at the same time, so the result can be viewed in the 3D model.
