2D CAD Drawing Board

Quick answer

This is a free online 2D CAD drawing board that runs in your browser. No installation or registration is required. It creates simple drawings to exact grid-unit sizes and exports PNG or SVG.

What this tool can and cannot do

Use it to draw lines, rectangles, circles, and polylines. You can enter line lengths and angles, rectangle widths and heights, or circle radii in grid units. Grid snap, endpoint snap, Ortho mode, joined endpoints, selection and movement, pan and zoom, undo and redo, and PNG or SVG export are available.

This is a lightweight drawing board, not a full CAD system. It does not create 3D models, import or export DWG or DXF files, manage layers, add text, save an editable project file, or place persistent dimension lines and labels on the drawing. Grid units are relative rather than built-in millimetres or inches.

• Good fit: simple floor-plan ideas, part outlines, furniture layouts, diagrams, and shareable sketches
• Not a fit: construction documents, manufacturing drawings, native AutoCAD files, layer-based drafting, or 3D work

How it compares to AutoCAD

This board is enough when you need a quick 2D sketch, want to set basic geometry to a chosen scale, or need a PNG or SVG that another person can view. It opens directly in the browser and keeps the workflow intentionally small.

Use AutoCAD or another full CAD application when the deliverable requires native DWG files, formal dimension annotations, layers, detailed documentation, 3D modelling, or an engineering, architectural, or manufacturing workflow. This tool does not claim AutoCAD compatibility and is not an AutoCAD replacement.

Example: draw a 1200 × 600 mm tabletop

Because the canvas uses relative grid units, first choose a scale. For example, let 1 grid unit represent 100 mm; a 1200 × 600 mm tabletop then becomes a 12 × 6 unit rectangle.

If you need freehand notes instead of scaled geometry, use the Online Sketchpad.

• Select Rectangle and click the canvas to place the first corner.
• In the floating fields, enter 12 for Width, press Tab, enter 6 for Height, then press Enter.
• Use Select/Move to position the rectangle, and export PNG or SVG when the sketch is ready.
• Record the 1 unit = 100 mm scale with the shared file. The tool does not place a permanent “1200 × 600 mm” label or conventional dimension lines on the drawing.

Set up a 2D drawing that can be checked

Start with a small coordinate plan: for example, draw a 120 by 80 rectangle, add a 30-unit circle near its center, and keep the origin and units visible in your notes. A simple first shape makes it easier to spot a mistaken scale or an accidental drag.

Use the same unit for every coordinate and dimension. The board is useful for quick layouts, teaching geometry, and exporting a visual draft; it is not a substitute for a surveyed coordinate system or a full CAD project with layers, constraints, and revision history.

Read the drawing and export safely

Before exporting, inspect the object list or canvas visually and verify that the intended lines, circles, and labels are present. A PNG is convenient for a slide, while an SVG keeps vector geometry for many downstream uses; choose the format according to the recipient.

An exported image does not prove that dimensions are to scale unless the receiving workflow preserves the drawing units. Keep the coordinate notes alongside the export, and recheck any measurement used for fabrication, compliance, or a client handoff in the required CAD system.

How to use

1. Choose Line, Rectangle, Circle, or Polyline, then click on the canvas to place geometry.
2. Keep Snap to grid enabled when you want points aligned to the visible drafting grid.
3. When drawing a line or polyline, place the first point, then type a length in the floating input or press Tab to enter an exact angle.
4. For rectangles and circles, place the first point, then type width and height or radius in grid units and press Enter for exact dimensions.
5. Use Connect endpoints mode to click two line or polyline vertices and join them into a shared endpoint; moving one connected line keeps the joint attached.
6. Use Select/Move to drag shapes; drag empty space to pan the view, and use the mouse wheel to zoom.
7. Use undo, redo, delete selected, or clear all to manage the drawing, then export PNG or SVG.

Use cases

• Sketch a rough room, desk, part, booth, or layout before opening heavier CAD software.
• Use the live length readout to estimate simple line segments and paths.
• Export SVG for slides, documents, design files, or later vector editing.
• Draft a 120 × 80 rectangle for a worksheet diagram.
• Draw a simple room outline before moving the final dimensions into CAD software.

Good to know

• A visual export is not a manufacturing or survey record.
• Keep a copy of the coordinate plan because an image alone is hard to edit.
