Elements drawn with arc segments can be altered using shape editing tools. 
 The Curved Edge Condition tool is an additional tool specific to curved edges. It sets them to project a flat surface to the edge or a curved surface that conforms to the arc edge of the element. 
- Right-click the shape edited curved edge element to modify, and select Properties. 
  
- On the Properties palette, click the Curved Edge Condition button located under Structural Floor Shape Edit. This opens the Curved Edge Condition Dialog. 
	 
 
	 Note: An element must have shape edited or shape editing points or split lines must have been added before the Curved Edge Condition property will be displayed. 
	  
- Select either Conform to curve for a scalloped surface, or Project to side for a flat surface. 
  
- Click OK to apply the condition. 
  
- Click Apply.
