Diaz Editor is a desktop CAD tool for solo installers and small trade teams. You model the building in 3D for the client presentation, then draft the same job in 2D for the workshop — and hand off a DXF that opens in any other CAD. No cloud, no account, no monthly fee.
3D building editor
Build up from site to building to level to walls to components. Selection is hierarchical and everything snaps to a grid, so a floor stays square while you work fast.
2D CAD drafting, DXF in and out
The 2D module is classic floor-plan drafting for the workshop, with a separate layer for each trade. Import a DXF to start from someone else’s drawing, and export a DXF that any architect, contractor, or installer can open.
A component library for the trades
122 built-in 3D objects — framing, furniture, kitchen, bathroom, and fixtures — thirteen of them energy: PV panels, a home battery, inverters, a heat pump, a buffer tank, a boiler, a smart meter, a DC combiner, and MVHR. For the 2D drawing there are 14 schematic symbols, six of them for energy.
Client-ready PDF reports
Export a cover page, the floor plan with a proper title block, and a bill of materials — one PDF you can hand to the client or the site.
Local-only by design
There is no cloud and no account. Your projects never leave your PC — the only thing that goes out is an anonymous update-check and opt-out usage statistics, never your drawings.
Runs in your language
The app ships in English, Dutch, and Spanish, and you switch between them while you work.
Windows and Linux today
Diaz Editor runs on Windows and Linux now. A macOS build is on the roadmap and waiting on the Apple Developer certificate — there is no date yet.
Built on a 14-year-old MIT codebase
Diaz Editor is a fork of Pascal Editor, an MIT-licensed CAD codebase that has been stable for 14 years. Because the licence is MIT, the code cannot be locked away from you.
Frequently asked questions
Does Diaz Editor work offline?
Yes. It is a desktop application — once installed it runs without an internet connection, and your drawings stay on your own machine.
Can I import and export DXF?
Yes, both. Import a DXF to start from an existing drawing, and export a DXF that opens in any other CAD program.
Which operating systems does it run on?
Windows and Linux today. A macOS build is on the roadmap and waiting on the Apple Developer certificate, with no date yet.
Is there a subscription?
No. Diaz Editor is a one-time purchase of €197 for three seats, with lifetime updates. There is no monthly fee and the licence does not expire.
