TL;DR

FreeCAD is genuinely free, open-source, fully commercial-usable, with the BIM workbench, Assembly4, and a thriving Python plugin ecosystem. Diaz Editor is €197 / €197 regular, building-focused, polished out of the box with PDF/BOM/library built-in. Trade-off: FreeCAD costs €0 but ~40 hours to configure and learn; Diaz Editor costs €197 and works in 30 minutes. For solo tradespeople with billable hours, €197 buys back roughly 40 hours of setup time.

When FreeCAD is the right choice

  • You love open-source and want to support / contribute to the project.
  • You have time to learn the workbench system and configure your workflow.
  • You need full source-code access — modify, fork, audit, redistribute.
  • You have €0 budget for CAD and 20-40 hours of learning time available.
  • Your work spans mechanical, FEM, BIM, and CAM — FreeCAD's workbench breadth is unmatched.
  • You're a hobbyist or student where time is more abundant than money.

When Diaz Editor fits better

  • You bill clients by the hour — 40 hours of setup costs more than €197.
  • You want building-focused workflow out of the box, not a general-purpose CAD platform you configure.
  • You want polished PDF reports (cover page, title block, BOM) without TechDraw workbench setup.
  • You want a curated trade component library (panels, framing, fixtures) instead of hunting plugins.
  • You value reliable commercial support — Juan answers email within 5 business days.
  • You want EN + NL + ES interface tested and consistent across all menus and dialogs.

Honest verdict

For makers, hobbyists, students, OSS-advocates

FreeCAD wins. €0 forever, full source access, community-driven, mature in 2026. If you have time-flexibility and value open licensing, FreeCAD is hard to beat. We use it ourselves for projects where we want full source control.

For self-employed tradespeople billing clients

Diaz Editor wins on time-to-value. €197 for a polished, building-focused workflow that works in 30 minutes. The 40 hours of FreeCAD setup are 40 hours not billed to clients. The math works out around €25/hour billable rate or higher.

Frequently asked questions

FreeCAD is free. Why pay €197?

FreeCAD is genuinely free if you have time to learn workbenches and configure workflow. Diaz Editor is €197 for tradespeople who'd rather pay once and have a polished tool that works out of the box. Time is the trade-off, not money.

How mature is FreeCAD in 2026?

Version 1.0 in late 2024 after 20+ years. By 2026 far more usable than its old reputation. BIM workbench + Assembly4 are workable. Learning curve still steeper than commercial CAD.

Can FreeCAD do what Diaz Editor does?

Yes architecturally — BIM workbench + add-ons replicate the workflow. Practically expect 20-40 hours of installation + configuration + learning. Diaz Editor delivers same workflow out of the box in 30 minutes.

Does FreeCAD export DXF and PDF?

Yes. DXF built in. PDF via TechDraw workbench with some setup. Diaz Editor's PDF report is built into core with no workbench configuration.

Commercial use rights?

FreeCAD = LGPL2+, fully commercial-usable, modify freely, no royalties. Diaz Editor = Pascal core MIT + proprietary modules under EULA. FreeCAD wins on freedom; Diaz wins on time-to-value.
