ShapeGen and the Lathe are both now available for sale at shop.onrez.com. For those of you not familiar, these are building tools of mine which construct large shapes by combining multiple prims. ShapeGen is useful for making large cylinders, cones and spheres. The Lathe allows you to build large curvy shapes by defining a bezier curve to be used as the outline. Both tools continue to be available through SLExchange.
