Viewport navigation

The 3D view is where you upload, inspect, and correct the model. It's a separate space from the flattened pattern layout — see Tools & marking cuts for how that one works.

Camera

Holding Shift (or Ctrl/Cmd) swaps what the left and right buttons do — left-drag pans and right-drag orbits instead — so if you only have one mouse button reliably available (a trackpad, for instance), Shift + drag covers panning without ever needing the right button.

Solid lines on the model are proposed cuts; dashed lines stay folded — the same convention the flattened layout uses, so the two views always read consistently.

While a Paint groups or Eraser tool is active, left-drag paints instead of orbiting. Hold Space or Alt to temporarily borrow the camera and orbit without switching tools — release it and you're back to painting exactly where you left off.

Checking scale against a reference avatar

Unfolder can show a reference avatar behind the model so you can sanity-check real-world size before you cut anything. Lower the Body transparency slider to see the avatar through the model; save a named avatar profile to your account to reuse the same body measurements across projects.

Filling the browser window

The Fill browser window button at the top right of the editor makes it fill the whole browser tab, with the site's header and footer out of the way, the same layout as fullscreen. Unlike fullscreen, the browser's tabs and your other windows stay where they are, so you can switch to a reference or another tool and come straight back. Click the button again to go back. The editor remembers your choice, so it opens filled next time too.
