Description
This program 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.
How to use
Ensure there is a vertical center line drawn in your workspace before starting.
The keyway section is drawn, and the temporary reference center line is automatically deleted.
- 1.Type key_s in the command line and press Enter.
- 2.Click the Intersection Point (at the top of the vertical center line) as the starting reference.
- 3.Enter the Total Width of the keyway.
- 4.Enter the Section Depth (vertical height).
