Resolving 'Reference Direction Computation' Warning — Lesson 5

What causes the warning below and how to overcome it?
“Reference Direction Computation: Alternate method used in Oriented Selection Set” 

This warning is coming from the fact that the x direction of a rosette is projecting onto the element as a point since it is normal. In this case ACP does not know how to orient the x, so it warns it is using a different method. To resolve this, we need to have a rosette that does not have the x direction normal to any elements in that oriented element set.
