From the developer:
The program ARTIC is intended to calculate pin-jointed structures such as traditional space meshes or expandable meshes. Also generates several types of spatial meshes with bars connected only at their ends nodes. Thus we can generate a flat rectangular mesh or diamond shape with the number of modules and size you want, using any of the types of modules that provides the program. Expandable meshes are also supported for generatin and calculation.
