How to Install : [CADian Lisps Download & Install Guide]

====================================================

1/ Command :

• PBB

2/ Description : This tool automatically draws a Push Button B-Contact symbol (Manual Operation / Automatic Return - Normally Closed) on a line, which is commonly used in electrical sequence drawings.

• Sequence Context: This is the 104th Lisp tool released. It requires you to　select the line and then a point along the line to determine the direction, replacing the older perpendicular　selection method.

• Symbol Scaling: On the first run, you set the　insertion scale (e.g., input 1 for a 3mm circle diameter). You can adjust this later using the FAC command.

3/ How to Use :

1. Type PBB in the command line and press Enter.

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

3. Select the Line where the symbol will be　inserted.

4. Click a point along the line to define the Direction (Up/Down or Left/Right).

5. The Push Button B-Contact symbol is automatically drawn at the　selected location.
