Using help lines

offset form the wall of the cove which is 500 mm all around the room.
1. Make sure you are on construction
mode
2. Go to help line tool (2).
3. Select line command (3)
4. Draw the line at the boundary of
the room form one corner to
another (4)
5. Set the offset as 0.5 m form
parallels spaced apart (5).
You can make many lines but for
this tutorial we need to keep it 1.
6. If the second line is place outside
the room rotate the line to be
inside the room, alternately make
the offset value in minus (-0.500
m).
7. Repeat the previous steps to have
4 lines around the room.
Tips:
 You can also you grid help line
and set x,y to 0.5 m each.
 If the cove is round you can select
a circle help line.
