Script Versions

• PlanarComponents.py - Original version (1.0): Aligns all selected vertices to best-fit plane
• PlanarComponentsAutoSnapToAxis.py - Enhanced version (1.2):
  • Auto-snaps plane normal to world axes (X/Y/Z) when within 0.1° threshold
  • Only moves vertices that are OFF the plane (selective displacement)
  • Detects existing coplanar vertices and preserves them
  • Shows in-viewport notification at top with moved vertex count and plane orientation
  • Preserves original selection mode after operation

Usage

After installing NumPy, run the main script from the Maya Script Editor.

Requirements

The script requires the NumPy library.

✅ Recommended installation method (Python-based)

Use the check_and_install_numpy.py script to automatically install NumPy from within Maya:

1. Open Maya.
2. Open the Script Editor.
3. Copy and run the contents of check_and_install_numpy.py.
4. The script will check if NumPy is installed, and install it automatically using mayapy.exe if needed.
