HI Plato- unfortunately my maths has a few holes when it comes to terminology and symbols, I can understand it quite easily, but have never studied it at uni, this unfortunately is my downfall, so I will try explain what I am looking for in picture form
the red dot will be a point that lies on the edge of a triangle- I need to draw a perpendicular line- (in green) from that point.
if you look in the side view (z/y axis), it must lie on the same plane as the triangle- hope that makes sense??
