1/ Command :

• KEY_S

2/ Description :
This tool is designed for mechanical drafting to automatically draw the cross-section and center line of a keyway.

• Automatic Layering: If the "CENTER" layer does not exist, it automatically creates it before drawing.

• Automated Drafting: It generates the detailed keyway geometry and centerlines based on simple dimension inputs, removing the need for manual line construction.

1. Ensure there is a vertical center line drawn in your workspace before starting.

2. Type key_s in the command line and press Enter.

3. Click the Intersection Point (at the top of the vertical center line) as the starting reference.

4. Enter the Total Width of the keyway.

5. Enter the Section Depth (vertical height).

6. Enter the Distance between the center lines.

7. The keyway section is drawn, and the temporary reference center line is automatically　deleted.
