This alpha version expires on 10 May 2027. Version 0.2.2 was released on 10 November 2026. It works offline, and the last day of use is 9 May 2027. After that you need a newer version from this page. The program changes the date at midnight UTC, which is 02:00 in Finland in winter and 03:00 in summer. Expiry never deletes, changes or locks your projects, settings or other files.
Version 0.2.2. Checksums: SHA256SUMS and their signature SHA256SUMS.asc.
Known limitation in version 0.2.2. At a large Interface size on a narrow window (Windows and Linux, for example 200 % on a 1024 px wide screen), the Arrange submenu opens on top of the More menu. A click on the Arrange row can then run Mirror vertically on the selected object. Undo (Ctrl+Z) restores it. To reach Window and Help, open More again and move to the row from the side, or use Find (Ctrl+K). A fix is on its way.
About the alpha
PirtoCAD is still in development. You may use the alpha for free, and we would value your feedback: what works, what does not, and what is missing.
- The finished version will have its own licence terms.
- PirtoCAD is not open source. The terms of use are shown the first time the program starts.
- Every public alpha version expires six calendar months after its release date. Until then it works offline. The expiry date is shown on this page.
- After expiry you need a newer version. Expiry never deletes, changes or locks your projects, settings or other files.
- Project files are not guaranteed to be compatible between alpha versions.
- Projects are saved as IFC 4.3 files by default, which other BIM software can also use.
How to send feedback
Choose Help > Send feedback (Ohje > Lähetä palautetta) while the problem is on screen. PirtoCAD builds the report on your own computer and opens a ready message in your own email program. Nothing is sent until you press Send there.
- Before sending, you see exactly what the attachments contain.
- The screenshot is taken of the PirtoCAD window only, never of the desktop or other programs. Text in the image is not hidden automatically, but you can blur the drawing area or leave the image out.
- PirtoCAD itself never connects to the internet: no update check, no usage statistics and no automatic error reports.

How smoothly large projects run depends on the computer. The Windows and Linux versions have been tested less than the macOS version. Known limitations are described in chapter 13 of the user guide.
The designer is responsible for the results. Default values and calculations support the designer. A calculation is only as good as its input data, so always check the default values and the results yourself.
