An FELine object is used to model beams, columns, and other structural elements that connect two Node objects. To create an FELine object, two Node objects and a Section object are required. The beta parameter represents the angle of rotation of the section around the Z-axis and is expressed in radians.
Example Syntax:
... <O T="FELine"> ... ... </O>
