Spline

		The Spline tool is located on the Draw toolbar.  This tool is a way of creating a multi-point curved line.  It could be used to create a curved roof or the edge of a curved pathway or road, rather than using a straightforward arc.  The Spline is created much like a series of lines are.  You can click in model space any number of times, and each added click will just continue building onto the Spline.
		Once you are done creating the Spline you want, you will hit enter to end the command.  You will now have the option to bend the ends of the line in whatever direction you choose.  As you move the mouse around, you will be able to see the end of the line bending around in the direction you have your cursor.  This is important if you want to use a Spline to connect two lines, and want the Spline to fit perfectly tangent to the end of each line. otherwise, there will be a slight corner in between the Spline and the lines.
		If you do not want to bend the ends of the Spline, just hit enter twice or right click twice to proceed through the command sequence.  In the image to the right, the first end was bent, and the second end was left alone by right clicking and ignoring the bend on that end of the Spline.
