Changing the Roof Line and the Floor Line of a Curtain Wall
You can modify the roof and floor lines of a curtain wall to create a non-rectangular curtain wall:
■
You edit vertex locations on the roof line to create steps, gables, and other roof conditions.
Modifying the roof line of a curtain wall
■
You edit vertex locations on the floor lines to create steps and other floor conditions.
Modifying the floor line of a curtain wall
You can also create non-rectangular roof and floor conditions by projecting to polylines.
AutoCAD Architecture offers multiple methods of editing roof lines and floor lines. You may want to begin by graphically
creating a custom roof line or floor line condition. You can then fine-tune that condition by specifying precise values
in the Roof/Floor Line worksheet on the Properties palette.
Offsetting or Projecting the Roof Line of a Curtain Wall
Use this procedure to change the height or the shape of the roof line of a curtain wall:
■
Offset the roof line from the current height of the curtain wall.
■
Project the roof line of the curtain wall to a polyline.
■
Project the roof line of the curtain wall to another object, such as a roof or stairs.
You can also create a polyline that represents the current roof line of the selected curtain wall. You can then use this
polyline to change the roof line of other curtain walls.
NOTE To project the roof line to a polyline, draw the polyline first in Elevation view. For best results, the polyline should be
parallel to the curtain wall. The polyline does not need to be in the same plane as the curtain wall.
