TL;DR

QCAD (by RibbonSoft) is a solid 2D CAD: stable, a one-time Professional license around €41, plus a free open-source Community Edition. It is deliberately 2D-only. Diaz Editor does 3D AND 2D, with a trade component library and 1-click PDF export toward quote, work-drawing, and bill of materials. For anyone who only wants 2D drafting at the lowest price, QCAD is strong. For anyone who wants 3D, ready-made parts, and direct shop-floor output, Diaz Editor adds that layer for €99 lifetime.

When QCAD is the right choice

  • You do only 2D drafting and don't need 3D building geometry.
  • You want the lowest possible price, or a fully free edition (Community).
  • You're comfortable with a somewhat technical, classic CAD interface and keyboard shortcuts.
  • You care about open source: the QCAD core is under GPLv3.

When Diaz Editor fits better

  • You want 3D for client presentations AND 2D for the shop floor in one tool — QCAD is 2D-only.
  • You want direct, clean PDF export toward quote, work-drawing, and bill of materials, without rework.
  • You'd rather start with starter files per trade (cabinet, stairs, frame, sheet metal) than with a blank canvas.
  • You work in Dutch, German, or Spanish and want onboarding in your own language.
  • You want a modern, guided interface instead of finding your own way.

QCAD is cheaper — we acknowledge that. The question isn't which tool costs the least, but what your €99 gets you: 3D building geometry QCAD doesn't have, ready-made parts, and 1-click output to the shop floor. For a tradesperson who saves an hour of prep per project, that difference pays for itself quickly. Do the math yourself: your hourly rate × hours saved versus €99 once.

Honest verdict

For pure 2D drafting at the lowest price

QCAD is an excellent choice. It's stable, proven, and cheap, with a free Community Edition to start with. If you don't need 3D and are comfortable with a classic interface, you get a lot of value for little.

For tradespeople who want 3D, speed, and shop-floor output

Diaz Editor adds the layer where QCAD stops. 3D building geometry, a trade component library, guided onboarding, and 1-click PDF export. You pay €99 once for less prep time and drawings that can go straight to client and workshop.

Frequently asked questions

Is QCAD cheaper than Diaz Editor?

Yes. QCAD Professional is around €41 once and there is a free Community Edition. Diaz Editor is €99 founding. The difference is scope: QCAD is 2D-only; Diaz adds 3D, a trade component library, and 1-click PDF export. You pay for less prep time and shop-floor-ready output.

Does QCAD do 3D?

No. QCAD is deliberately a 2D CAD program. For 3D building geometry you need a different tool. Diaz Editor includes 3D AND 2D in the same price.

Can QCAD open .dwg?

The free Community Edition cannot open DWG; that requires the paid Professional edition. Diaz Editor reads and writes DXF; direct .dwg is on the v0.5 roadmap.

What is the difference in shop-floor output?

QCAD users report that print and export results sometimes need rework. Diaz Editor focuses on 1-click PDF export with quote, work-drawing, and bill of materials in one pack, plus DXF for the workshop.

Is QCAD easier to learn?

QCAD is powerful but is often described as having a somewhat technical interface. Diaz Editor is built around one guided workflow with starter files per trade, so you don't begin with a blank canvas.
