Frequently asked questions

Yes — completely free. No subscription, no credit card, no hidden plan. The full feature set is available to everyone with no limits.

No. There is no login, no sign-up, and no email required. Open the app and start drawing immediately.

Any modern desktop browser — Chrome, Firefox, Safari, and Edge all work. KulmanLab is desktop-only; mobile and tablet are not currently supported.

Yes. After the first load the app is cached and runs entirely without an internet connection. Your drawings are stored locally so nothing requires a server.

In your browser's IndexedDB — on your own device. Nothing is ever uploaded to a server. Each browser on each device has its own independent storage.

Your saved drawings will be lost. Always export a JSON copy of anything important before clearing browser storage.

KulmanLab supports DXF (Drawing Exchange Format), not the proprietary DWG format. Most desktop CAD applications can export DXF, so export from your source app first.

DXF and JSON via Export — DXF for round-tripping with other CAD tools, JSON for full-fidelity saves (including dimensions and leaders) within KulmanLab. Print separately exports PNG, JPEG, WebP, or PDF images, with an optional area crop and monochrome toggle.

Yes. Type commands directly — LINE, CIRCLE, MOVE, TRIM, and 50+ others. The terminal supports history (arrow keys), autocomplete (Tab), and exact numeric input.

Full layer management: create, rename, freeze, lock, and isolate layers. Set color, linetype, and lineweight per layer. All layer data is preserved in DXF export.

Linear, aligned, radius, diameter, angular, and continue dimensions. All stored as standard DXF DIMENSION entities compatible with other DXF-capable CAD tools.

Yes. Select any entity to reveal grip handles at key points — endpoints, midpoints, centers, arc ends. Drag to reshape directly on the canvas, or type a value while dragging for exact placement.

Not currently. KulmanLab is a single-user tool and drawings stay local. Cloud sync and collaboration are outside the current scope.

Yes. KulmanLab reads and writes AC1032 DXF — a widely supported version. Files open correctly in LibreCAD, QCAD, BricsCAD, FreeCAD, and any other DXF-capable tool.

DXF is an open, text-based exchange format designed for interoperability. DWG is a proprietary binary format. KulmanLab uses DXF, which is readable by virtually every CAD tool.

For 2D drafting — yes. KulmanLab has a full command terminal, layers, snapping, dimensions, grip editing, and DXF compatibility. It does not support 3D, blocks/xrefs, or parametric constraints.

No. Your drawings stay in your browser and are never sent anywhere. KulmanLab uses Google Analytics for anonymous usage metrics (page views, session counts) — no drawing content is involved.
