Action: Read an Angle

With three or more cubes, the app lists the angles the cubes make with each other. Each angle is measured at a corner cube (the vertex), between the lines running to two other cubes.

Where angles appear

  • Each cube has one angle window: a list of every angle that cube is the corner of, one to a line.
  • It sits just to the right of the cube's own window, tops level. It stays there as you walk around, and follows the window when you move the cube.
  • These windows are always open — they are not minimized.
  • With three cubes, each list holds one line: that cube's own corner of the triangle. Add more cubes and each list gains a line for every new pair.

How to read one

Each line is written the way it is in math class: m∠BAC = 90.000° ≈ 1.571 rad — the measure of angle B-A-C. The middle letter is the corner cube, the one whose window you are reading; the outer two are the cubes its lines run to. So on cube A's window, that line says: standing at cube A, the line to B and the line to C meet at a right angle.

  • 90° is a square corner.
  • Values near 180° mean the three cubes are nearly in a straight line.
  • Values near 0° mean the two other cubes are in nearly the same direction from the corner.

Every line gives the angle in degrees and then in radians, each to three decimals, in columns so the decimal points line up.

Steps to measure a specific angle

  1. Place a cube at the corner you want to measure (the vertex).
  2. Place a cube along each of the two directions forming the angle.
  3. On the corner cube's angle window, read the line whose outer two letters are your two other cubes.

Showing or hiding angles

If the angle windows clutter the scene, hide them from the app window with Hide Angles, or show only angles with Isolate Angles (see Action - Show, Hide, and Isolate Windows).

In the export

The TXT export lists every angle once — m∠ABC and m∠CBA are one angle — under its name, with the corner cube, the degrees, and the radians.

The 3D exports (USDZ, OBJ, STEP) carry the same list, in the same notation, standing beside each cube on its own Angles layer, so you can hide or move the readings apart from the rest of the build.
