Build-upAU

Draws the layers of a wall, floor or roof in one go, such as plaster, masonry, insulation and render, each a band of its thickness with its material's hatch. Soft insulation is drawn with its loop line. It stays one element: the inspector changes its layers.

How it works

1. Click the points of the path the layers start from, such as the face of the cut wall, or type them; U takes a point back, and Enter ends the path. E instead lays it along a straight edge you click.
2. Click the side the layers go to. The first layer lies against the path, the others follow outwards. The tool stays on for the next build-up.
