heyas; netwrksrf is... well, to me, its kinda like lofting in 2 directions at once. you build the horizontal and the vertical cross sections, and skin it. there's a tutorial on that at my goodie page. i think every program is kinda flaky about booleans. i tried to boolean union my glaucus body to its head, and that came out a TOTAL mess. (in lightwave.) but then again, i used a cone to cut the top off the daz jack o lantern and make a lid, and that came out splendidly. it depends on the meshes, i guess.
