How can I create a set of points in a grid on a surface.
I tried creating evenly spaced vertical lines; extrude those to a surface; intersect with surface to create vertical curves.
I then created a set of horizontal lines; extrude those to a surface; intersect with the lines.
I would expect that I would now have a set of points. Instead I get a mixture of curves and points.
The images here shows after the second intersection.
