I came here to find out how to form an elliptical cone, but didn't see a simple way. So I had to figure it out for myself.
Yea, this is an old thread. I'm posting this here in the hope that someone else searching for the solution might find it.
Draw a circle.
Make a triangle with one point on the centre of the circle, one point on the edge, and the third point at the height you want the cone.
Select the edge of the circle.
Choose "Tools —> Follow Me" and click on the triangle's face. You should now have a circular cone.
Choose "Tools —> Scale". A yellow box with green handles should appear.
Click on the centre green handle on the vertical box of the selection that is in the dimension you want to make smaller to create your ellipse.
Touch the modifier key that causes both sides to scale about the centre. On the Mac, that's the OPTion key.
Move the cursor inward until you get the size of ellipse you want, or type a scale factor into the "Measurements" box.
That's how I created the following elliptical cone, with a length-width ratio of 0.5.
