Line

The Line command creates straight line segments between points. It is one of the most frequently used drawing tools in IGEMS and serves as a foundation for more complex shapes and geometry.

🔹 How to Use

1. Activate the command:
   Use the Line tool from the toolbar or press the short key L.

2. Specify the start point:
   Click anywhere in the drawing area or enter coordinates manually (e.g., 100,50).

3. Specify the next point:
   Move your cursor and click the next position, or type coordinates or relative distances (e.g., @50,0 for a horizontal segment 50 units long).

4. Continue drawing:
   Each new point creates a straight segment from the last one. Continue adding as many segments as needed.

5. Finish the command:

   • Press Enter or Spacebar to finish.

   • Press ESC to cancel without completing.

   • Press Backspace to undo the last segment.

🧠 Tips

• Relative Input: Use the @ symbol for relative distances. Example: @0,100 draws a vertical segment 100 units up.

• Undo Last Segment: Press Backspace at any time to remove the last line segment without restarting the command.

• Ortho Mode: If you want to restrict movement to horizontal or vertical lines, enable Ortho Mode (shortcut: F8).

• Object Snaps (OSNAP): Use OSNAP to snap to endpoints, midpoints, or intersections when precision matters.

• Continue from Endpoint: You can continue a line from the end of an existing line to create connected geometry.
