LINE

Draw connected straight line segments by clicking, or by typing length and angle.

What it does

LINE draws straight segments one after another. Each segment is a separate Line object.

Where to find it

Ribbon: Draw › Draw › Line (submenu: Line - 2-Point, Line - From Midpoint, Dashed Line)
Command line: LINE (Alias L)

Steps

Type L and press Enter. The Prompt bar shows LINE: specify first point.
Click the start point (or type coordinates).
LINE: specify next point (Esc to stop) Click the next point, or type the length in the Smart Input box, press Tab, type the angle, and press Enter.
Repeat as many times as you need. Press Esc to finish.

Try it: Side profile of a 6-step staircase

Risers of 175 and treads of 250 mm, which meets the comfortable-stair rule (2 x riser + tread = 600). One LINE command does it all with relative @ coordinates.

Type L, press Enter, type 0,0 and press Enter.
Type @0,175 Enter (riser), then @250,0 Enter (tread).
Repeat step 2 five more times for 6 steps in total. The line now ends at 1500,1050.
Type @0,-1050 Enter, then 0,0 Enter to close the shape, and press Esc.

Challenge: Try a gentler stair with @0,150 risers and @300,0 treads and compare the total length.
