This tool is designed to quickly draw a Slot Hole (Keyway) on a single end of a shaft.

  • Auto-Layering : Automatically creates the CENTER layer for the slot's centerlines.

  • Interactive Direction : Allows you to interactively specify whether the slot should be drawn on the left or right side of the starting point.


3/ How to Use :

  1. Type SLOTH in the command line and press Enter.

  2. Specify the Center Point of the shaft end.

  3. Click a point to the Right or Left to define the direction for the slot.

  4. Enter the Diameter (Width) of the slot.

  5. Enter the Distance to the center of the slot's arc (Length).

  6. The single-end slot is generated immediately with centerlines.
