The Action Modifier button, available in the Tinkercad iPad app, can be pressed to give additional functionality and workflows. Similar to the "Shift" modifier key when using Tinkercad with a keyboard in a browser, the Action Modifier button in the 3D editor can do the following while pressed:
- Constrain object movement in one direction on the Workplane (orthogonally).
- Scale an object equal in all directions while dragging a handle. (uniform-scale)
- Rotate in snapping increments of 45 degrees.
