This program expands the capabilities of a 2D truss analysis by integrating a 3DOF space truss system. It allows for the addition of new nodes (LamdZ) and facilitates the computation of forces and reactions at joints. The advancement accommodates up to 6 degrees of freedom per joint, utilizing matrices to compute loads and displacements across various spatial configurations. Enhanced functions enable seamless transitions from 2D to 3D truss analysis, allowing for flexible modeling of complex structural systems with precise load distribution.
