Rigid 3
his is a software to calculate three-dimensional structures of bars with rigid joints, semi-rigid or pinned. Default bars unions to nodes will be stiff, but the user can modify to your taste the degree of embedment of the same at each end so as to calculate the structure more closely resembles reality. The results are the deformation of the structure and the efforts diagrams. This program can import structure geometry from a DXF file an export the graphics results at the same format.
