Structure System, introduced in SOLIDWORKS 2019 and enhanced in 2020, offers a flexible way to create welded structures without complex 3D sketches. It supports defining members using points, planes, and chains, with new options like “up to point” and “up to plane” for precise control. Primary and secondary members can be split during creation using dimensions, instance counts, or references. Corner management automatically determines trims for simple and complex intersections. SOLIDWORKS 2020 adds the ability to pattern entire structure systems—linear, circular, or mirrored—while maintaining member intelligence, enabling advanced designs. This feature streamlines creating multi-profile structures with efficient trimming and alignment.
