How do i get the tangent of an ellipse if I only have the angle of the mating line ?
Hi. I've been trying to solve this since 1:30 (Its now 6pm). I have an ellipse that needs to meet an arc. They both have to meet at a perfect tangent (because I am going loft many of these).
I've searched the web and my old geometry books, but can't get the answer.
CAD will get the tangent from a point, but I need to have perfect tangents at the angle. I'm happy with old geometry if there is no cad solution, I just need this to proceed with this job.
