To Offset or Project the Floor Line of the Wall

Use this procedure to change the height or the shape of the floor line of a wall:

• Offset the floor line from the current baseline of the wall.
• Project the floor line of the wall to a polyline.
• 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.

1. Select a wall.
2. Click Wall tabModify panelRoof/Floor Line drop-downModify Floor Line.
3. Change the floor line of the wall:

   If you want to …	Then …
   offset the floor line from the current base line of the wall	enter o (Offset), and enter an offset distance. Enter a negative value to project the floor line below the current wall base line.
   project the floor line to a polyline	enter p (Project), and select the polyline.
   project the floor line to another object, such as a slab or stairs	enter a (Auto-project), and select the object to project to. When projecting to stairs, make sure that the bottom riser or the stringer does not create a zero-height segment of wall.
   generate a polyline of the current floor line	enter g (Generate), and select the walls for the polyline to be created from.
   remove any changes to the floor line	enter r (Reset), and select the walls to change.
