Use case
Variants on one plan.
A house in Builder is live geometry, not a baked shell. Iterate five roof variants on the same plan — the walls stay editable — split the work by area across the studio, and show the client the real shadows before anything is built.
The studio loop
From brief to variants, before the client call.
Iterate, don't restart
Walls, roofs, openings — everything stays editable. Duplicate the design, swap the gable for a hip roof auto-fitted to the same perimeter, compare on the same plot.
Real booleans, real openings
Windows, exterior doors with steel pull handles, interior doors, passages — cut as real CSG booleans. Rectangle, circle, triangle for the modern-barn gable.
Split the design by area
Editor shares carry areas: the outside, the inside, the garden, colours & finishes anywhere, light & weather. Hand the landscape designer the garden without touching the rest.
Client sun studies
Pick the place and the date, play the day in 15 or 45 seconds, and walk the client through the shadows the house would really cast on that plot.
Precision is a feature.
- The wall graph computes rooms and the perimeter from the plan — junctions split at T and X, corners mitre themselves
- Gable and hip roofs auto-fit the minimum-area oriented rectangle of the plan
- Sun position from Meeus series, ~0.01° — solstice-checked, equinox sunrise due east, equation-of-time extremes QA'd
- 4,096² shadow map fitted to the site — about 2 cm per texel over a 45 m radius
- Presence on every view: an orbiting peer shows · viewing, with a name and a colour that follows their account
- Every change is one undoable step — Ctrl+Z through the whole variant war
"A variant used to cost a week of remodelling. Now it costs one roof type and an undo stack — and the client decides looking at the real sun."
— the studio loopFriday, variant review
The client asks for a hip roof. You ask for two minutes.
Same plan, new roof, auto-fitted to the perimeter, shadows recomputed for the same June afternoon. The variant is in the room before the call ends — and the walls never had to move.
