Measure your real world in true 3D space.

Cattail.Nu SpaceCube places translucent measuring cubes in your immersive space. Move them and get exact positions, and distances, angles, slope, and level between them — live, in world and local coordinates.

Apple Vision Pro Mixed immersive space No account. No subscription. No tracking.
01 / Built for makers

One instrument, three trades.

The same cubes read out whatever your work needs — coordinates for code, fractions for the shop, proportion for the studio.

Developers

Read live Vector3 position, quaternion rotation, and Euler angles in both world and a local frame you define. Export a 3D file (usdz, obj, step) or the raw numbers as text.

Carpenters

A spirit level, slope in percent, pitch in inches-per-foot, and distances in metric or true imperial fractions. Visualize a build, check a deck for level, assess a ramp, or find a center without a tape.

Artists

Find the true center of a canvas, level a picture on the wall, and lay out proportion in the space itself. The cubes float alongside the real work, not on a flat screen.

02 / See it

Real panels, floating in your immersive space.

Every readout is a spatial window that hangs beside the cubes it describes.

03 / What a cube does

Place a marker. Everything is measured from its center.

Two hands, no tape

One-hand pinch to move a cube, two-hand pinch to rotate it. Up to twelve markers can float in your immersive space at once, each lettered A through L.

World and local frames

Use your Vision Pro's world origin or set your own local origin.

Distance, angle, slope, level

The measurement window (in Metric and Imperial) over each cube pair shows straight-line distance, split into 4 equal segments, and has a spirit level, slope, angle, and pitch.

Save your workspace

Your layout is pinned to the real space between sessions, so Restore puts every cube back exactly where you left it. You can also save your workspace and open it again later.
