Offsetting or Projecting the Floor Line of the Wall
Use this procedure to change the height or the shape of the floor line of a wall:
â– Offset the floor line from the current baseline of the wall.
â– Project the floor line of the wall to a polyline.
â– Project the floor line of the wall to another object, such as a floor slab or
stairs.
You can also create a polyline that represents the current floor line of the
selected walls. You can then use this polyline to change the floor line of other
walls.
NOTE To project the floor line to a polyline, draw the polyline first in elevation
view. For best results, the polyline should be parallel to the wall. The polyline does
not need to be in the same plane as the wall.
