Draw 4-Hole Bolt Circle with Base

This tool automatically draws one large central circle surrounded by four smaller circles arranged symmetrically, including their centerlines.

Efficiency

It combines multiple drawing steps (circles, arrays, and centerlines) into a single command sequence.

Compatibility

This is a dedicated Cadopilar Lisp tool and works only within Cadopilar.

The complete geometry (large circle + 4 small circles + centerlines) is drawn automatically.

1. 1.Type C4C in the command line and press Enter.
2. 2.Click the Center Point for the main circle.
3. 3.Enter the Radius of the Large Circle.
4. 4.Enter the Radius for the Placement of the small circles (the distance from the center to the small circles).
5. 5.Enter the Radius of the Small Circles.
