I am trying to draw a cylindrical rod with two through holes in the rod. In other words, looking at the side of the rod, there will be two through holes bored through the rod and the center lines of the through holes, will intersect and be perpendicular to the centerline of the rod. The holes will not intersect and will be about an inch or so apart.
The problem I am having in trying to figure out how to do this, is that the two holes will both be bored at 45 degree angles in relation to each other. In other words, looking at an x ray view at the rod end, the two bores will form a cross. Which means the lengthwise view of the rod - in order to be portrayed correctly - the holes will need to appear slightly elliptical and off center from the rod centerline. So I guess in order to project, I need to determine the lenght of the minor axis of the ellipse.
How would draw these in DC - or how would I determine using DC tools the shape of the ellipse of the holes given that the holes will be at 45 degrees in relation to each other, in other words, along the centerline of the rod, they will be off center from the rod centerline by 22.5 degrees...Is there an easy quick tool to do this on DC, or do I need to just to pull out my old college math books and re learn ellipse formulas & do the math?
Thanks for any advice.
