Drawing lines

Lines can only be added by using the middle mouse button.

  1. Place the mouse pointer on the starting point of the line. For exact placement, observe the coordinates in the left corner of the status bar.

  2. Press and hold the middle mouse button and move the mouse pointer to the end of the line.

  3. Release the middle mouse button.

The line appears in your working field.


The system will display the message concerning “dangling points” also in case of lines which do not belong to an area. You need to connect both ends of the line to an area or, as called in Simulation Mode, to a region.
