Insert MCCB

This tool automatically draws an MCCB (Molded Case Circuit Breaker) symbol on a line, useful for electrical sequence drawings.

Directional Control

Unlike older versions where you　selected a perpendicular direction, this updated tool requires you to　select a point along the line to determine orientation.

Symbol Scaling

On the first run, you set the　insertion scale (e.g., input 1 for a 3mm circle diameter). This scale applies to all electrical symbols in this series.

(First Run Only) Enter the Symbol　Insertion Scale (e.g., 1).

1. 1.Type MCCB in the command line and press Enter.
2. 2.Select the Line where the symbol will be　inserted.
3. 3.Click a point along the line to define the Direction (Up/Down or Left/Right).

To Change Scale Later

Type fac, press Enter, and input a new scale value.
