+===== Distance Parallel To Path =====
-the command distance_parallel_to_path computes the dot product of a vector from the start to point p, with the straight line path defined as the position at event1 to position at event2
+The command Distance_Parallel_To_Path computes the dot product of a vector from the start to point p, with the straight line path defined as the position at Event1 to position at Event2. In the figure below, the blue line is the parallel distance from the point P.

+The pipeline command below will calculate the distance travelled by the MID_PSIS [[visual3d:documentation:c3d_signal_types:target_data_type|TARGET]] parallel to its path between the [[visual3d:documentation:c3d_signal_types:event_label_data_type|events]] START and STOP. This distance will not be normalized.
