One model. Every drawing.
A minute with CreaBIM 1.1: the model, your layout, selection and Edit mode, profiles, and the drawings that come from it.

Design-first BIM, modelled like Blender.
CreaBIM is modelled like Blender, made for architects. It offers direct modelling for design work, not only documentation: Edit mode for points, edges and faces, masses with modifiers, profiles, Divide, view areas and workspaces.
Its own workflow, a clean interface, and a Blender modeller's instincts in a BIM tool.

Design in one tool. Document in another.
Most practices run two programs and a handover between them: a modeller for the design, a drafting or BIM tool for the permit set. Every revision crosses that boundary by hand, so the drawing you submit is only as current as the last time someone updated it.

- 02Design developmentdesign tool

- 04Rebuild in BIMauthoring
- 05Reconcile the seteach revision
Three of these five steps exist only because the model and the drawings live in different files.
- 3D view live
- Plan 1:50
- Section cut
- Elevation 1:100
- Sheet A0–A4
- IFC 4
- Schedule csv
- Take-off xlsx
One edit lands in all of them, in the same moment and the same undo step.
Small, fast, and quiet.
CreaBIM is written in Rust and draws on your graphics card. Sections and 3D drawings are built on every core in the background, so dragging a wall never waits for the other views.

- 16coresUsed to draw sections and 3D views
Measured with the starter house on a 16-core Windows desktop. Your numbers will vary with your machine and your model.
Drawn from the model, not traced over it.
Sections and elevations are generated from the model. Cut walls, slabs and openings are drawn heavy; what lies beyond is projected with hidden lines removed.
- Draw sections and elevations in a plan, or inside another section
- Level datums, section and elevation marks, door swings and window symbols
- Sheets with a title block, scales and live views, exported as vector PDF
- Shade any 3D view or elevation in material colours, on screen and on sheets

Your own sections, drawn once.
Draw a coping, a gutter or a steel section in its own view, with snaps, guides and typed lengths, then use it for sweeps, columns, beams and railings. Change it later, and the elements made with it take the new shape when you apply it.
- Several shapes in one profile, with holes and voids you pick
- Trace over a picture, a DXF or a view of the project
- Move, rotate, align and copy, with box select
Modelled like Blender. Made for architects.
The dense, keyboard-first way of working modellers love, given to buildings instead of characters: areas you split and arrange, panels of tabs, a key for every move and a value typed when it must be exact. What you move are walls, slabs and sheets.

CreaBIM 1.1.1 for Windows, macOS and Linux: installers, packages, a portable zip, or the source.
Get CreaBIM →Is it really free?
Yes. CreaBIM is open-source software under GPL-3.0: free to use, study, change and share.
Does it need the internet?
No. It runs on your computer and never needs a connection.
Can I use it on real projects?
Not yet for production work. It's ready to explore and to model with; check where it stands before you rely on it.
Does it open Revit or ArchiCAD files?
Through IFC: export IFC from those tools and open it in CreaBIM. Native .rvt files are a closed format.
Is there a Mac version?
Yes. A universal app runs on Apple Silicon and Intel Macs, macOS 11 or later.
