What is Building Design?
Building Design models a building as real elements on levels — layered walls, doors and windows that cut their own openings, floors, ceilings, roofs, columns, beams, stairs, railings, furniture and rooms that measure themselves. Every plan, section and 3D view is generated from that one model. You can use it without an account.
Key features
- Walls, curtain walls, doors, windows, floors and roofs
- Stairs, ramps, railings, columns, beams and foundations
- Rooms with live area, perimeter and volume
- Furniture, fixtures and building-services elements
