I need to make an engraved analemma (see pic) and I have made a sketch and spline with the 365 X,Y coordinate data points representing each day of the year. I now would like to use these points, which I used to generate an extruded cut (the material enclosed by the 2 loops of the spline is removed), as points from which to engrave a scale like a protractor or ruler scale to indicate days of the month. I'd like to do this of course without drawing each scale line individually. The line from each point needs to be perpendicular to the cutout at that point, like the scale lines on a protractor would be, ideally each a vee extruded cut. Is there any way to do this in even a partially automated way, maybe with a macro? The points are NOT equally spaced along the spline....
