Contractor use cases

  • Quotation 3D views: Sketch the project, drop in the proposed work, generate a client-ready 3D PDF in under 15 minutes. Wins the job before the competition has sent their PDF.
  • Work-preparation drawings: Layer per discipline (structural, electrical, plumbing, HVAC) for the team on site. Export DXF to subcontractors.
  • Permit applications: Floor plans, elevations, bill of materials, all in the same project. Export PDF permit-pack.
  • Renovation surveys: Sketch the existing, mark what changes, export the before/after PDF for the client.
  • Coordination with subcontractors: DXF round-trips cleanly between Diaz Editor, AutoCAD, BricsCAD, and FreeCAD.
  • Team handoff: Pro license = 10 device seats. Lead designer drafts, junior pulls up the same .diaz file for take-offs.

Frequently asked questions

Why one-time pricing matters for small contractors

5-person team × SketchUp Pro $399/yr × 5 years = $9,975. AutoCAD LT same team: $11,375. Diaz Editor Pro: €247 once. €6,000-€8,000 stays in your pocket.

Does Diaz Editor replace our current CAD entirely?

For most small contractors, yes. Common pattern: keep one AutoCAD seat for final .dwg delivery if mandated, design everything in Diaz Editor.

How does the team license work?

Pro is €247 once for 10 device seats. Each seat is one active installation; move seats between devices by deactivate-then-activate. Lifetime updates, no recurring fees.

Is data secure for GDPR-sensitive clients?

Local-first. Your client files stay on the drawing workstation and are never uploaded — no cloud, no third-party account. The app only makes anonymous update-checks + opt-out usage stats (which features are used, never file contents). Backup via your existing OneDrive/NAS.
