# Hinge derivation methods

Select one of the Hinge derivation methods illustrated below:

1 – Offset and elevation. Enter an offset (4) from the horizontal alignment, and the elevation (5) of the hinge position.

2 – Offset and slope. Enter an offset (6) from the horizontal alignment, and the slope value (7) from the intersection of the horizontal and vertical alignments to the hinge position.

3 – Offset and vertical distance. Enter an offset (8) from the horizontal alignment, and the vertical difference (9) from the intersection of the horizontal and vertical alignments to the hinge position.

If the alignment consists of only a horizontal alignment, the only hinge derivation method available is Offset and elevation.
