Frequently asked questions
Can I switch between metric and imperial mid-drawing?
Yes. The unit system can be changed at any time from the canvas settings panel. Existing element dimensions are recalculated automatically.
Is this a replacement for AutoCAD or Revit?
No — it’s a lightweight browser-native drafting tool for early-stage layouts, quick diagrams, and documentation drawings. For construction-grade BIM files, you still need dedicated CAD software.
Does any data leave my machine?
No. All drawing and export processing runs entirely in your browser. Nothing is sent to a server. Drawings are stored locally in browser IndexedDB.
