.. _auto_curve_get_crossover_point:

*COMPUTE CROSS-OVER POINT WITH ANOTHER CURVE*
=============================================

Finds the intersection point between two curves and returns either the X or Y coordinate of that crossover. Use this worker when you need to identify where two time-history or XY curves cross each other.

When to use

     - First input curve (XY vector or CurveGroup — if a group, the first curve is used) to intersect against curve2.

     - Selects which coordinate of the intersection to return: 'x' for the Cross-over X-Value or 'y' for the Cross-over Y-Value; defaults to 'select' (no output) if left unset.
