Typically, insertion points are used to model bearing locations, therefore, it is recommended to have one insertion point for each bearing.
Location: Select the support lines
Longitudinal Offset [ft]: Longitudinal offset along the PGL (Projected Grade Line) from the support line.
Transverse Offset [ft]: Transverse Offset from the PGL. When the transverse offset of the support line is non-zero, the entered value will be added to the transverse offset of the support line, resulting in the summation being used as the transverse offset along the PGL for the insertion point.
When working with a support line that has a skew angle greater than 0 in OpenBrIM, it is important for users to specify the transverse offset(T) along the support line, not along the PGL(Y). This is demonstrated in the figure below.
If a support line has a skew angle greater than 0 and longitudinal offsets greater than 0 are being used, then the longitudinal offset parameter is applied perpendicular to the support line.
