Quote - Combining figures into one.
Example: You load a Figure, drag-drop-conform, some clothing over it, and then use the "combine" function to combine all these into a single rigged and posable figure.

Most call that boolean.would be nice if all the cgi app's called everthing the same thing.

Boolean operations deal with intersecting volumes, combining two solids into one, using a solid to remove part of another solid, or to create a new solid from the intersections of more than one solid.

Poser clothing usually is not solid, and generally isn't supposed to intersect the underlying figure, except maybe the older clothing that had "capped" sleeves etc.

For Poser to remove e.g. the parts of the arm hidden by a sleeve requires an entirely different algorithm to determine the hidden part of the arm.  To call this a "boolean" operation would be incorrect as it is only similar in application.
