ShapeDesigner displays all geometric section properties in real time in the CAD at design time. This means, for example, that you can move a point and see how the section properties such as area or inertia evolve as the movement is occurring.

Contrary to most software available, ShapeDesigner makes no assumptions or restrictions on the
calculation of shear and torsion section properties. ShapeDesigner uses an advanced and efficient finite
element approach to calculate these constants. The complexity of the finite element approach is
hidden from the user. *There is no general method for computing shear and torsion
section properties without using this finite element approach.*
