The live 3D preview: check your layout without leaving 2D

A small 3D window sits in the corner of the plan and follows what you're looking at, with your real furniture. Drag inside it to turn it, pull its corners to resize it, and tap expand for the full 3D view.

Switching between 2D and 3D just to check that a chair faces the right way gets old fast. The 3D preview shows the part of the plan you're looking at in 3D, right next to it, and updates as soon as you let go of something you moved.

Step by step

  1. 1

    Find it in the corner

    On a computer the 3D preview opens at the bottom right of the plan; on a tablet held upright it's at the top right. It shows the area of the plan you're looking at, from above, with your furniture, and follows you as you pan and zoom. Selecting a piece doesn't move it. On a phone it starts closed: tap 3D preview at the top right for a small window, and tap the window to make it bigger.

    Turn, zoom and move it

    - Drag inside it (one finger on a touch screen) to turn and tilt the view and see furniture from any side. - Scroll or pinch to zoom; right-drag or move two fingers to slide. - Drag its title bar to move the window anywhere over the plan. - Pull the blue tabs on its corners to make it bigger or smaller. It remembers its place and size; Reset (shown once you've changed it) puts it back. - The expand button opens the full 3D view.

    Hide it, and bring it back

    Click the X to hide it. It stays hidden on that device until you click the 3D preview button (next to the compass at the bottom right on a computer, top right on phones and tablets).

    Hidden? The 3D preview button brings it back.

Tips

Check facing as you place

Rotate a chair in 2D, let go, and glance at the preview: it updates straight away.

Use the full 3D view for walkthroughs

The preview is for quick checks. For walking through, materials and pictures, open the full 3D view.

Frequently asked questions

Can I see 2D and 3D at the same time?

Yes. The 3D preview shows a live 3D view next to the plan while you edit in 2D. Drag inside it to turn it, and pull its corners to make it bigger.

The 3D preview disappeared. How do I get it back?

You closed it with its X. Click the 3D preview button at the bottom right of the plan (top right on phones and tablets).

Does it slow down the editor?

It works in the background, so drawing and dragging stay smooth, and it updates when you let go. On older devices that can't run it, the button doesn't appear.
