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

1/ Command :

• EFi

2/ Description :
This tool is designed for electrical drawings (or similar schematic work) where you need to create a fillet (rounded corner) connection between lines without trimming the original lines.

• Non-destructive Fillet: Creates an arc connecting two lines but keeps the original lines intact (unlike the standard FILLET command which usually trims them).

• Directional Control: The direction of the fillet arc depends on which side you click relative to the base line.

• Input: Requires the fillet radius,　selecting the first line (e.g., top part of a vertical line), and then clicking a point to indicate the direction (e.g., to the right).

3/ How to Use :

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

2. Enter the Fillet Radius.

3. Select the First Line (e.g., click the upper part of a vertical line).

4. Click a Direction Point (e.g., click to the right to curve right, or left to curve left).

5. A fillet arc is drawn connecting in the specified direction, preserving the original geometry.
