A spline is a smooth curve that passes through or near a set of points that influence the shape of the curve. 
Draw a Spline
 
   
  - Click 
		. 
		
 
	  
- (Optional) Enter 
		m (Method). Then enter either 
		f (Fit Points) or 
		cv (Control Vertices). 
	 
 
- Specify the first point of the spline. 
	 
 
- Specify the next point of the spline. Continue specifying points as needed. 
	 
 
- Press Enter to end, or enter 
		c (Close) to close the spline. 
	 
 
 
 
Draw a Spline Tangent to and Connecting Two Lines or Curves
 
   
  - Click 
		 
	 
 
- (Optional) Enter 
		con (Continuity) and enter a tangency option. 
	 
 
- Select a line or curve near an endpoint. 
	 
 
- Select another line or curve near an endpoint. 
	 
 
 
 
Convert a Spline-Fit Polyline to a Spline 
 
   
  - Click 
		. 
		
 
	  
- Enter 
		o (Object). 
	 
 
- Select a spline-fit polyline and press Enter. 
		
The selected object changes from a polyline to a spline.
