Common questions ↓About CrackCAD 3D →All help →
Getting started

Get going in three steps.

01

Open it

Open CrackCAD 3D from its page. There's nothing to install and no account needed.

02

Start a design

Begin with the sample workshop, or choose a room, a shed or a blank project.

03

Keep a copy

Export your project as a .crackcad.json file every now and then, so you have a backup.

Common questions
My projects are gone

Projects are saved in the browser you used. Clearing browser data, a private window or a different browser can leave them behind. Open the file you exported to get them back.

How do I move a project to another device?

Export it as a .crackcad.json file and open that file on the other device.

It's slow or blank

CrackCAD needs a modern browser with 3D graphics (WebGL) turned on. Phones and tablets work with touch controls.

Can I build straight from the drawing?

Always check the measurements and construction details yourself before you build anything for real.
