This issue must have been covered in this forum in the past, but I could not find any relevant topics when I did a quick search. So here goes...
I have an ellipse with a series of datum points placed on its perimeter. How do I draw a tangent & normal to the ellipse located at these points?
I have been struggling with this in the sketched mode, but for some reason wildfire will not allow me to force a tangent line to pass through a predefined point.
I might be able to eventually figure it out by writing up mathematical equations, but thought there should be a less painfull way of doing this.
Thanks
