The Filter Type list allows you to select from the following filter types:
GAUSSIAN
SPLINE
UNIFORM
TRIANGLE
CYLINDRICAL.
If you select GAUSSIAN, UNIFORM, or TRIANGLE then the workplane is critical. For these three filter types, the following applies:
If you select the Linear option, the filtering occurs normal (i.e., perpendicular) to the workplane.
If you select Polar option then the filtering occurs in a radial direction within the workplane.
