Draw to Scale

Lay out a sheet on A4, A3 or A2 at 1:50, 1:100 and more, with a title block and scale bar, and save a PDF.

Questions

Free online 2D CAD — common questions

Is BenCAD free?

Yes. The drawing tools, dimensions, snapping and PNG download are free with no account. BenCAD Pro adds tools such as offset, fillet, mirror, DXF export and the print-ready sheet.

Do I need to download or install anything?

No. BenCAD runs in your web browser on a phone, tablet, laptop or desktop. Open bencad.com and start drawing.

Does BenCAD work on an iPhone or Android phone?

Yes. It was built for touch screens first, with tools sized for fingers, snapping and pinch to zoom. It works just as well with a mouse and keyboard.

Can BenCAD open and save DXF files?

Yes, with BenCAD Pro. Import DXF files from AutoCAD, QCAD or LibreCAD, and export your drawing as a DXF in millimetres with sorted layers.

Can I print a drawing to scale?

Yes. The print-ready sheet in BenCAD Pro lays your drawing out on A4, A3 or A2 at a true scale such as 1:50 or 1:100, with a title block, scale bar and north arrow, and saves it as a PDF.

On the free version, drawings stay on your device and are never uploaded. You can save a .bencad file or download a PNG at any time.

Help

Getting started

Draw

Pick a tool in the toolbar and drag on the canvas. Lengths show in millimetres as you go, and points snap to the grid and to line ends.

Pan and zoom

Pinch with two fingers to zoom and drag with two fingers to pan. With a mouse, scroll to zoom. Tap the fit button (the four corners at the top) to see the whole drawing.

Undo and redo

Tap ↩ and ↪ at the top, or press Ctrl+Z and Ctrl+Y. Try things freely — you can always step back.

Save your work

In the ☰ menu, SAVE AS keeps a .bencad file you can open again later. DOWNLOAD saves a PNG image to share.

Draw

LineStraight lines with snapping

Pick LINE. Tap LINE in the toolbar, in the Shapes group.
Drag from start to end. Press where the line starts and drag to where it ends. The length shows in millimetres as you go.
Lock the angle if you need to. Tap ANGLE LOCK and choose 0°, 30°, 45°, 60°, 90° or type any angle. The line then only grows along that angle.
Let go. The line is placed. Its end points snap to the grid and to the ends of other lines.
