I haven't used the mould tool in that way, yet. About the only thing I've done is create a complex shape in Xara, then export it as an AI/EPS file, to import into Wings 3D to create a one-way extrusion of the shape, then export that to OBJ format, to import to Vue Creator to use for 3D illustrations...

The first image is an aerial view of a Japanese imperial capital within a distant star system. The shape of the city is the chrysanthemum kammon, or the imperial family crest. The second image, was a depiction of the Shogun's imperial flagship, the crest on it's back is the butterfly kammon of the Taira house of the Shogun.
