Draw walls
The dashed line is what you click along; the grey band
shows where the wall body lands. Trace the outside face of exterior walls
and the numbers match the plan directly.
Add opening
Height is to the springing line, where the curve starts. A radius of half the width gives a semicircle; larger is flatter.
Click any wall to place it — you can drag it along the wall afterwards.

Grade areas
An area overrides the lot profile inside its outline — a
neighbour's block sitting higher, a terrace cut flat, a bank. Later areas win
over earlier ones, and each eases into the ground around it over its blend
width so it reads as a bank rather than a cliff.
Ground
The reference grid gives way to a real surface — grass, gravel,
paving — once one is chosen. Shows in 3D and the walkthrough.
