What does work-preparation actually need from a CAD tool?

Three things: a clean way to capture the design intent (from sketch or imported plans), layers per discipline so each subcontractor sees only their work, and clean DXF/PDF export so the right drawing lands in the right hands. Diaz Editor handles all three out of the box.

Can I import an existing AutoCAD or SketchUp project as a starting point?

Yes. Diaz Editor reads DXF natively. Export the AutoCAD or SketchUp project to DXF, open in Diaz Editor as a reference layer, and start your work-preparation on top.

Each component placed in Diaz Editor sits on a layer (structural, electrical, plumbing, HVAC, etc.). Toggle layers to see only one discipline. Export per-layer DXF to subcontractors so each gets only their work — no clutter, no risk of mis-installing something.

Is there a multi-user collaboration mode?

Diaz Editor is single-user per device by design (privacy-first, no cloud). For team handoff, save the .diaz project file to a shared NAS or OneDrive folder; the next user opens it on their seat. For real-time multi-user editing, Aurora or BIM 360 fit better — but that comes with the subscription cost.

Werkvoorbereiding workflow

Capture the design intent. Sketch from architect drawings, import existing DXF as reference layer, or start a new 3D building model from scratch.
Separate disciplines into layers. Structural, electrical, plumbing, HVAC, framing, finishes — each on its own layer. Toggle visibility while detailing.
Add the execution detail. Place components from the library, dimension critical points, annotate per discipline.
Generate the deliverables. Per-layer DXF for each subcontractor. Combined PDF for the project manager. Bill of materials for procurement.
Hand off. Save the .diaz project to a shared folder. The next werkvoorbereider opens it on their seat — no cloud sync needed.

Why werkvoorbereiders choose Diaz Editor

Hierarchical building model (site → building → level → walls → components) keeps complex projects organised.
Layer-per-discipline workflow built in. No plugin purchase, no custom config required.
DXF round-trips cleanly to AutoCAD, BricsCAD, FreeCAD, and other downstream tools.
PDF report generation with cover page, title block, and BOM — no LayOut or Studio upgrade.
EN + NL + ES interface for international project teams.
Local-only — client and project data stays on your workstation.

Frequently asked questions

What does work-preparation need from CAD?

Capture design intent, layers per discipline, clean DXF/PDF export. Diaz Editor handles all three out of the box.

Can I import existing AutoCAD/SketchUp work?

Yes. Export to DXF from the source tool, open in Diaz Editor as a reference layer, build your work-preparation on top.

How do layers work?

Each component sits on a layer (structural, electrical, plumbing, HVAC, etc.). Toggle to see one discipline at a time. Per-layer DXF export to subcontractors.

Multi-user collaboration?

Single-user per device by design (privacy-first, no cloud). For team handoff, save .diaz to shared NAS/OneDrive folder. For real-time multi-user, Aurora or BIM 360 fit better — but with the subscription cost.
