STS has produced a free SuperLIGHT version of all software it produces, in order to provide whoever is interested in purchasing these tools, not a simple demonstration, but a functional program to all effects (obviously with opportune limitations), in order to verify the exactness of the calculation results other than understand the modality of the uses. The two programs WinCAD (CAD 20 and 3D professional) and WinEditor (text editor in RTF format), can be used both interfaced with other software, as well as completely independently. They are shareware, they have no limitations. The following are the limits on the SuperLIGHT versions for each software:
