After assigning a cross section to a line body, a new property will appear where you can specify the type of offset to apply. There are four choices:
Centroid: The cross section is centered on the edge according to its centroid. This is the default setting.
Shear Center: The cross section is centered on the edge according to its shear center.
Origin: The cross section is not offset and is taken exactly as it appears in its sketch.
User Defined: Allows to you to define the cross section's offset. When this option is chosen, two additional properties will appear in the Details View for you to specify the X and Y offsets.
