To create a non-rectangular curtain wall, sketch a straight curtain wall and then edit its elevation profile, or join a straight curtain wall to any roof. 
- Open a floor plan view or a 3D view. 
 
- Click 
  
 (Wall: Architectural).

- Select a Curtain Wall type from the Type Selector drop-down. 
 
- Create the wall, using one of the following methods: 
  
- Draw the wall: By default, Line is active. (If it is not active, click Modify | Place Wall tab
Draw panel
 (Line), or select another draw tool.) See 
		Sketching. 
		As you draw a wall, you can quickly set its length by entering a value on the keyboard, taking advantage of the listening dimension feature. See 
		  Use listening dimensions. 
		
 
		If you want to flip the orientation of the wall about its location line, press the 
		  Spacebar as you draw the wall. This works for all wall drawing tools, such as rectangles, circles, and 3-point arcs. 
		
 
	  
Note: You cannot flip the wall orientation while drawing a wall from an ellipse or partial ellipse. 
		
	 
- Pick Lines (
): Select existing lines. Lines can be model lines or edges of elements, such as roofs, curtain panels, and other walls. 
	  
- Pick Faces (
): Select either a massing face or a generic model face. The generic model could be created as in-place or family file based. See 
		Creating Walls from Mass Faces. 
		Note: You cannot pick the face of a wall created with an ellipse or partial ellipse.
		
		Tip: To highlight all vertical faces on the mass or generic model, press 
		  Tab. Click to place walls simultaneously on each highlighted face. 
		
 
	  
 
 
- Select the wall, and edit its elevation profile or join it to a roof. 
 
- Add curtain grids and mullions, as desired.
