click the icon to turn it ON or OFF. (or press F8 to toggle)

  1. Type z [Space bar], type e [Space bar]. This will zoom extents your drawing area.
  2. Make sure you have this requirement Layers for your drawing.
  3. Make sure layer 0 is selected as current layer.
  4. Click Line, specify first point at 0,0. Type 0,0 [Enter].

Move your cursor to right side and type 3 [Enter]

Move your cursor upward and type 3 [Enter].

Your line should look like this;

Click Offset, specify offset distancet o0.25. Type 0.25[Enter].

Click on vertical line as object to offset,
