ok here is my question vertex A needs to rotate around Vertex B baised on B''s Orientation or in other words Vertex A is at a Fixed distance away from B, Vertex A needs to be at the right spot where if you draw a line with the orientation of B it goes through both verteces. eh I hope that came out clear ): can anyone help me with this? cheers!

i may not have understood the question correctly, so bear with me...

this could be represented by two rotations around axes that are both perpendicular to B''s orientation vector.

an easier way is just to calculate the distance between A and B originally, then project A onto B''s vector.
i''m pretty sure this is done by just multiplying each component of B''s UNIT orientation vector by the distance.

good luck!
