You can use the Slide Line and Swing Line edit commands to edit attached plot lines. Attached plot lines are plot segments that were created with the Plot Layout Tools subdivision commands.
Using layout tools is the only activity possible while the Plot Layout Tools toolbar is open.
Specify the angle, quadrant bearing or whole circle bearing to edit the plot line. Preview graphics display if a solution can be obtained.
When prompted for the angle, quadrant bearing or whole circle bearing, you can press Enter to enter a 90 degree angle as this is the default angle.
OSNAP must be turned off when using the Swing Line commands.
