One segment
Series of Connected Segment
• Start the Line command by using one of the following methods:
1. PULLDOWN MENU = DRAW / LINE
2. TOOLBAR = DRAW
3. Type = L <enter>

Drawing Lines
Lines are drawn by specifying the locations for the endpoints.
• Move the cursor to the location of the “first” endpoint then press the left mouse
button.
• Move the cursor again to the “next” endpoint and press the left mouse button.
Continue locating “next” endpoints until you want to stop.
(OSNAP should be ON)
