## Description

KulmanLab is a professional-grade 2D CAD editor that runs entirely in the browser. There is nothing to install — open the URL and start drawing. All geometry is stored in your browser's IndexedDB; no file is ever sent to a server. The app works offline after the first load.

It is designed for engineers, architects, and technical illustrators who need a capable DXF-compatible tool without the friction of desktop software or the privacy concerns of cloud CAD platforms.

## Key features

- Full command terminal with history, keyboard navigation, and fuzzy autocomplete (matches letters anywhere in a command's name, ranked by match quality then by actual usage frequency)
- 50+ drawing commands: Line, Polyline, Circle, Arc, Ellipse, Rectangle, Spline, Hatch, Text (MTEXT), Dimensions, Leaders, and more
- Polyline arc segments — toggle Arc mode (A) mid-polyline for AutoCAD-style tangent arc segments, fully supported by render, selection, grip editing, trim/extend, DXF, and hatch boundaries
- Rotate has a Copy toggle (C) — rotate duplicates instead of the original selection, AutoCAD ROTATE-style
- Selection filter: narrow a large multi-selection by Type, Layer, Color, Lineweight, or Linetype before bulk-editing, via a filter icon in the property panel
- Hatch fills any closed boundary with a pattern (ANSI31 and other standard patterns built in); Hatch Manager browses the pattern library and lets you upload your own .pat files, which shadow built-in patterns of the same name
- Array Grid repeats a selection in rows and columns with typed spacing — no point-picking
- Layer management with color, linetype, and lineweight per layer
- Grip editing on all entity types (lines, arcs, polylines, dimensions, text, viewports)
- Snapping: endpoint, midpoint, center, intersection, perpendicular, tangent, nearest, grid
- Angle tracking with configurable increments (10°, 15°, 20°, 30°, 45°, 90°)
- Layout / paper space with multiple layouts and viewport editing
- ISO 5455 scale selector for viewports
- Print manager: PDF and PNG/WebP export with a Draft/Normal/Presentation/Max Quality (DPI) setting; preview renders through the exact same path as the export, so what you see is what downloads
- DXF import and export (compatible with LibreCAD, QCAD, BricsCAD, FreeCAD)
- Match Properties command (copy color, layer, linetype, lineweight)
- Properties panel showing entity details
- Undo/redo with full history
- Adaptive CAD grid with snap-to-grid
- Themes: dark mode by default, teal (#4A8580) accent

## Workflow

1. **Model** — draw geometry in model space using commands, snapping, and layers
2. **Configure paper format** — switch to a layout tab, set the paper size, and add viewports at the desired scale
3. **Print / export** — open the print manager (Ctrl+P) to export PDF or PNG, or use File → Export DXF

## Frequently asked questions

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

**Do I need to create an account?**
No. There is no login, no sign-up, and no email required. Open the app and start drawing immediately.

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

**Does it work offline?**
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.

**Where are my drawings stored?**
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.

**What happens if I clear my browser data?**
Your saved drawings will be lost. Always export a JSON copy of anything important before clearing browser storage.

**Can I open .dwg files?**
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.

**Which export formats are available?**
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.

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

**Is there layer support?**
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.

**What dimension types are available?**
Linear, aligned, radius, diameter, angular, and continue dimensions. All stored as standard DXF DIMENSION entities compatible with other DXF-capable CAD tools.

**Can I edit geometry with grips?**
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.

**Is real-time collaboration supported?**
Not currently. KulmanLab is a single-user tool and drawings stay local. Cloud sync and collaboration are outside the current scope.

**Are KulmanLab DXF files compatible with other CAD software?**
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.

**What is the difference between DXF and DWG?**
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.

**Can KulmanLab replace my desktop CAD software?**
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.

**Does KulmanLab collect my drawing data?**
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.

**Are cookies used?**
Cookies are used for Google Analytics, which collects anonymous usage metrics (page views, session counts).

## Privacy

KulmanLab collects no drawing data. Your DXF files and canvas state are stored locally in IndexedDB — never uploaded. Google Analytics is used for anonymous usage metrics (page views, session counts), and the app is funded by ads served through Google AdSense. A region-scoped consent banner (Google Consent Mode v2) asks for opt-in before Analytics or ad cookies are set in the EEA, UK, and Switzerland. No account, no login, no server-side storage.
