Hi, I need to create planes from points. Is that possible?  
If I have two points, I understand that I need a third coordinate to define a plane, so I would like to orient that plane along an X, Y, or Z direction, (for example: R Condylar Point - Right Gonion - sagittal)

I need these planes to use them as reference planes for measurements and also for clipping.  
Is that also possible?

Thanks!
