I am looking to project lines on to surfaces perpendicular to the camera. The issue I have come across is regarding the projection, the curve that is to be projected on to the surface raps around the entire brep? In reality, all I need is for it to project on to what the camera sees not everything it touches and the reset. I have looked in to lists and selecting the faces I want it to use, It worked but not too well, once there is more complicated geometry. Once the lines are projected is there a way of filling them in to change the colour? Any ideas?
