1. 01

   Open the free drawing studio

   Click Start Drawing on the homepage. No username, password or account is required.

2. 02

   Choose a starting shape

   Use the colour-coded Profiles tab to select a quick shape or search the 58 editable section starters. All are reference-only sketches, not developed fabrication blanks.

3. 03

   Set exact leg dimensions

   Tap a leg or choose it in the Precision leg editor, then set its length (mm) and direction (°). The endpoint and later points move together so downstream legs retain their lengths and angles. You can also drag green nodes or type exact X/Y coordinates. The new Shape orientation controls mirror, rotate, reverse point order or move the first point to X=0, Y=0 without redrawing. Mirroring and rotation use the first point as their pivot. Use Undo if a change is unsuitable. The origin is not a backgauge position.

4. 04

   Check Sketch Review

   Fix zero-length edges, repeated endpoints and crossing segments before DXF export. Short edges cause warnings. Point fields show and retain the numeric precision entered or imported (including values finer than 0.1 mm). The DXF exporter rounds coordinates to 0.001 mm and blocks a file if that rounding would create invalid geometry; keep the JSON backup for original sketch values. These are basic checks only, not fabrication approval.

5. 05

   Save, back up, then export

   Save up to 200 profiles locally (browser storage permitting), search them by name or material, and delete individual entries when no longer needed. The library never silently drops older profiles when full. Unsaved edits also create a browser-only recovery draft; on a return visit, choose Restore unsaved sketch or discard it. If another tab changes the draft, autosave pauses and warns you to export JSON before reloading; saved-library edits are also paused when another tab changes that library. Export the current sketch as JSON before reloading, and work in one Studio tab at a time. This is not a substitute for a JSON backup. Use Backup all to download your library. DXF is intended for CAD inspection; SVG includes explicit millimetre dimensions and checks basic centreline geometry before download, but some viewers may rescale it; verify any imported dimensions. SVG remains a drawing reference, not a manufacturing drawing, and JSON can be reimported.

Understand your files.

Frequently asked questions.

Private Studio includes 58 searchable open-centreline starters across six categories, editable width/height/return inputs, precise new-leg construction with relative or absolute angle, and a selected-leg midpoint command. You can measure between arbitrary points, inspect segment lengths and geometric turning angles, compare against saved drawings or captured sketches, and export a CSV leg schedule or downloadable HTML reference sheet. The Studio also has a live extrusion-style 3D concept view and a Duplicate action for locally saved profiles. Both the 3D view and the new geometry inspector are reference tools. Turning angles are not press-brake bend angles. The 3D depth slider changes only the visual reference. These tools do not add solid geometry, material thickness, bend allowance, tooling clearance, validated fabrication flats or manufacturing instructions. Save your work to this browser, then export a JSON/library backup for safekeeping. A downloadable HTML reference sheet may be opened and printed from the browser, but it is not a workshop drawing. Check DXF dimensions independently after import.
