BIMopen

This repository holds the built website of BIMopen, served by GitHub Pages, and the test builds of the program in its Releases. It contains no source code: only the pages, their translations and images, as they are published.

BIMopen is a BIM modeller written in pure Rust: you model the building (levels, layered walls, doors and windows, curtain walls, floors, roofs, stairs, rooms) and plans, sections, elevations, 3D views, schedules and sheets are views of the same model, kept in step. It opens IFC files (IFC2x3 and IFC4) as new projects, exports IFC4 and prints vector PDFs. It runs in the browser, on Windows, Linux and Android, with two interface styles in six languages: Italian, English, German, French, Spanish and Arabic (right to left).

Developed with Claude Code.

Test builds for Windows (10/11, 64 bit), Linux (x86_64) and the web version are published as prereleases under Releases, with a SHA256SUMS.txt file to check them. The download page of the website lists the latest one and what changed.

[!WARNING] Partial versions, for testing only. These alpha builds are incomplete and meant only to try the program. They may contain errors, change without notice and give wrong results: do not use them for real projects or for documents with professional or legal value. They are provided "as is", without warranty of any kind; their use is entirely at the user's own risk, and the author accepts no liability for damage, data loss or any other consequence of their use. Always keep a copy of your files.

The source code is not public yet.
