Line

1. Type command line to draw line
2. First select the start point of line

To draw a line with certain angle and length:

1. You can first select the start point

3. Input 10 and press ENTER to constrain the length of line as 10mm
4. Click mouse left to confirm and finish

Polyline

If you want to draw a few continues line segment, you can use command polyline

2. Rectangle
