I am trying to work out the correct way to make a truncated cone, and it occurred to me that someone, somewhere, must have equations that can help with this. I found this page, but I’m not sure it’s right. I never seem to get answers that will work.
Picture a cone with a base diameter of 6 (D1) and at 2.75 (L), the diameter is 3(D2). How to make a flat pattern, given those three dimensions? If these equations worked for me, I could make a function out of it, but I have not been able to get that far. I end up with a very flat cone.
This just isn’t my long suit. I can’t tell if I am misreading it or what.
And this post used to have a lot more information, but the latest beta of ecto ate the extended entry.
If I follow the equations on that page, I end up with a very flat cone and the smaller of the two openings is twice the size it should be (it should be 3 inches in diameter, and it becomes a circle with a three inch radius somehow).
