// What it does
Rotates the working mesh 90° around X, Y, or Z. Paint, boundaries, marks, and selections all follow the rotation — you don't lose work. Apply multiple times to compose 180° / 270° rotations.
Affects Symmetry pairing, Plane paint axis, Direction paint axis, Build orientation, and Layer view.
// When to use it
- The STL loaded on its side or face-down (common with downloads).
- You want +Y to be 'up' so Direction paint and Plane paint behave intuitively.
- You want symmetry to pair across the model's actual mirror axis.
- Aligning the model with the slicer's expected orientation before export.
// How to use it
- Setup tab → Orient model section.
- Click X, Y, or Z — model rotates 90° around that axis.
- Click again to keep rotating (180°, 270°, back to 0°).
// Tips
- This rotates the mesh, not just the camera. Camera-only orbit doesn't change the model's true orientation.
- Direction paint axes wrong? Usually means the model is rotated relative to world. Orient first.
- Re-pair Symmetry after rotating — the axis you wanted may now be different.
