Sketch a building.
Get the BIM model.
Draw rough walls, rooms and openings. Bimsta lifts your sketch into a fully editable 3D model — joins solved, openings hosted, PDF ready. Runs in your browser, free to start.
From sketch to construction documents
Bimsta is the fastest way to turn a building idea into a real BIM model. Sketch the layout, let Bimsta solve the geometry, then refine, document and export.
Architects and small firms use it because it removes the weeks of legacy BIM training between an idea and a deliverable — and runs in any browser.
- Sketch → BIM: rough drawing becomes a real Wall/Opening model
- Full 3D BIM element model: walls, slabs, columns, roofs
- PDF export for construction documentation
Everything you need to design
From first sketch to construction documents, all in one place.
Sketch → BIM
Hand-draw walls, rooms and openings on a 2D canvas. Bimsta validates the layout, solves wall joins, hosts your doors and windows, and builds a multi-floor 3D model you can keep editing.
- Sketch walls and partitions across multiple floors
- Auto-solved wall joins and intersections
- Doors and windows hosted on walls automatically
- Result is a real Wall/Opening model — fully editable
