Select one or more splines and then adjust the

click Outline and then drag a spline. If the spline is
open, the resulting spline and its outline will make
asingleclosedspline.
Original and outlined splines
Note: Normally, if using the spinner, you must first select a spline
beforeusingOutline.If,however,thesplineobjectcontainsonly
one spline, it is automatically selected for the outlining process.
Center—When off (default), the original spline
remains s tationary and the outline is offset on
one side only to the distance specified by Outline
Width. When Center is on, the original spline and
the outline move away from an invisible center line
to the distance specified by Outline Width.
B oolean—Combines two closed polygons by

the first spline you select, and deletes the second
one. Select the first spline, then click the Boolean

Note: 2D Booleans only work on 2D splines that
are in the same plane.
There are three Boolean operations:
