Analysis Functions

Properties (sections, variable inertia, cable, bars and trusses, plates and shells, user-defined).

Model (springs, imposed displacements, inclined supports, member offsets, deflections (beams), introduction to finite elements (plate elements, mesh contours, integration lines, iso-contours)

Loads (thermal loads, wind loads and wind profiles on members, weights and masses definition, loads cg calculation)

Graphical functions (advanced edition commands, disconnect from the structure, rotate section option, alignment of the sections)

Edit (operations, remove orphan joints, combine nearby joints, recalculate)

Analysis (data verification, example with errors to be fixed)
