Selecting this option will open the **Create Polygon** window.\\

Once this window is displayed the user can use the left mouse button to select on the screen the shape for the curve and join all the points together.\\
The user can leave the continuous curve open or closed. To close the curve check the **Snap** box and this will allow the user to select the point of the beginning of the curve to close it up.

The Selection window will open and the user has to select the first point, second point, and last point in the spline.\\
Once completed and the **OK** button selected the **Spline **window will open. This window is used to adjust the tolerance of the spline and to give the user the option of having the spline closed or open.\\
