Auto Centerline & Circles

This tool allows you to automatically draw a base set of cross-hair centerlines and then rapidly add multiple concentric circles (either visible outlines or circular centerlines) around a single center point.

Update (v1.1) : Now includes automatic LTSCALE adjustment.

Auto-Sizing

The initial centerlines are automatically drawn slightly larger than the largest diameter you specify.

Layer Control via Prefix

You can easily switch between drawing a normal circle (Layer 0) and a circular centerline (Layer Center) by adding a prefix to your input.

Add Concentric Circles:

1. 1.Type ACL in the command line and press Enter.
2. 2.Click the Center Point for the circles.
3. 3.Enter the Diameter for the main cross-hair centerlines (typically the size of your largest intended circle).
4. 4.Press ESC to finish.

Example

Type 100 and press Enter. The cross-hairs are drawn to fit a 100mm circle.

For a Normal Circle (Layer 0)

Type the diameter starting with 0.

Example

050 -> Draws a 50mm circle on Layer 0.

Example

085 -> Draws an 85mm circle on Layer 0.

For a Centerline Circle (Layer Center)

Type C followed by the diameter.

Example

C70 -> Draws a 70mm circle on the CENTER layer.

Example

C100 -> Draws a 100mm circle on the CENTER layer.
