Hi
Im trying to create a cone with the top cut off, im sure there
is a proper name object, I need to draw it in Autocad then cut it
out from paper and assemble it as a 3D model.
I know the diameter top and bottom and the slant length but I cant
figure out how to calculate the radius of the 2 arcs which will wrap
around the 2 circles.
I have uploaded a picture of what I mean.
