Section Composer will calculate the section properties of almost any shape that are needed in structural analysis. The 3D visualization of nonprismatic sections with tendons pass through make it an absolute must for LARSA 4D users. This user-friendly and completely integrated tool is based on the same powerful LARSA 4D technology.

• Add custom sections to LARSA model.
• Nonprismatic section applied to a span of multiple members.
• Linear or parabolic variation for nonprismatic sections.
• Built-up sections using any shape from AISC steel tables, standard AASHTO bridge girders, and LARSA's modifiable parametric shape tables.
• Build plate girders including box-girders and hybrid girders.
• Graphically create and edit any arbitrary shape by drawing with the mouse or specifying coordinates.
• Composite sections with multiple materials.
• Holes and openings of any shape.
• Create a customized library of sections
• 3D visualization with rendering.
• Section properties calculated in real-time, even for custom shapes: Area, Moment of Inertia, Torsional Constant, Section modulus, Center of Gravity, Shear Center, Shear Area Plastic Moduli and Warping Constants (plastic resisting moments).
• Easily move and rotate shapes using drag-and-drop.
• Copy, Paste, Align, Transform, Shift, Rotate, Flip, Snap
• Point and click to assign the stress calculation points
• Export to DXF
