Relationship Add methods have checks to ensure that a new relationship does not contradict previously placed relationships. For example, AddHorizontal will return an error if the line already has a vertical relationship. This check can be turned off to enhance performance. The optional “guaranteed_ok” argument, if set to 1, bypasses relationship checking. However, this feature could leave the system in an unsolvable state, so use it with extreme caution. It is best to use this feature only on a new element with no other relationships.
