Sheet Lightning Lite 5.0 is a cut down, simple to use, parametric only version of Sheet Lightning 5.0 (parametric design only). It unfolds a range of sheet metal designs that can be altered by editing parametric values (i.e. dimensions). The library has a comprehensive set of designs including cones, cone intersections, tees, junctions, adapters (square-to-round, square-to-oval etc), junctions, divertors, breeches, lobster back (or swept/segmented) bends, and other specials. Many designs include oblique/skew offsets. The library can be expanded using the full (non-Lite) version. The website offers additional new designs, as they become available, that are instantly usable on download.
