Orientation of reference points in conceptual mass environment

[yuri0167]

Hey everyone, I am modelling a pattern based curtain panel and Im using reference points to drive my geometry. I have a problem with the orientation of the points that I place on reference planes. When I place the point its positive orientation ( the blue arrow) points downward. Of course I can pull it manually in any direction that I want but when it comes to driving it with parameters it becomes difficult when the parameter drives it in the wrong direction. 

Is there any way to flip the orientation so that it is compatible with my offset parameters?

It depends where and how you hosted the point....it will follow the orientation of its host.

You do not need to flip it ...just add an inverse parameter...ie: if the Height of that pointing up is A then that of the one pointing down would be A*(-1)
