Hi. I need to project some points on a plane down to a cone under it. Any thoughts?

If your plane is not a standard plane so you can't use along-x, y or z I would create an axis from the pt and the plane and then you could use an intersection relationship between the axis and the surface for your 3d sketch point. If I had a lot of points to do and it was possible I would extrude a surface and use the edges as axes

Use 3D sketch place points on cone (on surface) and along Z to corresponding points.
