sparPositionType, a sparPostion defines a location within the componentSegment where a spar in mounted. Those positions are combined to spars by using a list of spar position uIDs. The order of the sparPositionUIDs must be the same as the order of the points on the real spar (from root to tip or from tip to root).

Please note: orientation of a spar must be always outbound or always inbound. A zigzag spar orientation where e.g. the spar starts at the root, goes to the tip and goes back to another point at the root is not allowed.

Please find below a picture for an example definition of 3 spars in one wing, by using spar position points and spar segments:
