This is a sheet metal designing software.
Sheet Lightning is a sheet metal pattern development software. This tool can help you build unfolded sheet metal patterns for products like Tees, Bends, Junctions, Intersections, Cylinders, Cones, Ducts, Flue, Diverters, Adapters, Chutes, Chimneys, Hoppers, Structural Steel and many others. Sheet Lightning and Mesh Unfolder are quite powerful 3D CAD engineering design software products. For organizations designing sheet metal products on a big scale the tool would be indispensable; particularly the houses that design special products. This tool has a powerful parametric design environment. It also brings you a comprehensive design library and a full 3D CAD design environment for customized design. That is quite a combination to result in this very powerful tool. The library has most of the library components in a ametric form so that a whole family of a components of same type can be created very easily. You can create this family of components from a template and varying the dimensions.
The 3D CAD environment lets you design from simple tees and bends to complex multi-intersection of any level of design complexity. Everything from simple cylinders, cones, rectangular ducts and ovals, to adapters, adapting any of these section types, intersections between any of these types and multi-intersections of any of these types. You would thus be able to handle breeches, lobster-back or segmented bend and very unusual or complex one-off designs. These pieces can have center line offset and oblique or skewed sections. The interface this tool offers is quite intuitive; at least for the designer types. With a good range of features, this is a very good tool.
