Spline mask

The Spline Mask object is essentially a boolean object but for splines. It allows you to perform boolean type operations on splines e.g. combine 2 or more splines or subtract one spline from another. The advantage of course is that the splines remain separate so there is no need to connect them. This then allows for some creative and easier animation plus easier editing.

The spline mask is treated as a spline object when it is used as a child object of a Sweep Nurbs or Extrude Nurbs object. One thing about the Spline Mask object is that it works best when all splines are on the same plane. The Spline Mask object is very easy to use and there aren't many parameters. One thing I would like to see is when the "Create Cap" option is enabled and a cap is created that there is an "N-gon" option just as you have on the caps option for Extrudenurbs objects.

When you want to use more than 2 splines with the Spline mask object you have must use nested Spline Mask objects. It's important here that you name your splines carefully as the hierarchy can soon become messy with lots of nested Spline Mask objects.

The following is a simple example of using the Spline Mask along with the Object Manager structure.
