Walls, windows and roofs: lifting a floor plan off the page

Wall snapping, smart joins and parametric roofs — three steps from a floor plan to a complete building.

Walls: straight or curved

DeepCosmo’s wall tool supports both straight and curved drawing. Straight walls suit standard rooms, while curved walls can outline arc balconies, round towers and other organic spaces. With snapping enabled, wall endpoints align automatically and the structure stays accurate to the millimeter.

Doors, windows and openings

Doors and windows are standalone parts you can drag straight into a wall. They sense the wall’s thickness and direction automatically, and you can keep adjusting width, height and off-ground distance after placing. Want a fully open elevation? Delete a wall segment or use the door-opening tool.

Parametric roofs

Pitched roofs, gables, dormers and ridges automatically follow your existing wall outlines. Change a roof parameter and the slope, overhang and thickness update live — no manual modeling. Combined with the multi-floor slab tools, you can build from one story to three, or even a taller tower.

  • Switch freely between pitched and flat roofs
  • Gables and dormers generated with one click
  • Slabs, stairs and ceilings fully support multi-story buildings
