About Us Revcad Software are specialist engineering CAD software developers. 
Download SHEET LIGHTNING v5.2 NEW - Download Mesh Unfolder v2.0 Sheet Lightning and Mesh Unfolder are unique and powerful CAD software products for sheet metal engineering and manufacturing. They have become an indispensable tool to companies with special design requirements. Sheet Lightning combines a powerful parametric design environment with a full 3D CAD design environment. Together they provide an unrivaled tool for design in its product area and a capability for unlimited user library expansion. Ideal for education! Sheet Lightning is unfolding software for unwrapping sheet metal designs. It combines an integrated parametric library and full 3D CAD system with unlimited design capability. Designs ranging from simple tees and bends to complex multi-intersection of any level of design complexity (see examples). It handles 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. This enables it to handle breeches, lobster-back or segmented bend and very unusual or complex one-off designs. All pieces can have center line offset and oblique or skewed sections. The program also has an increasing number of very powerful special design capability. 
A much awaited new release - Sheet Lightning Version 5.0 is now available for download (released on 18 January 2003), bringing the program to the forefront of CAD technology. See the Screen Shots.
