I fought and fought with sketch-up and then it crashed on me, so I ended up doing another one that is even more off than my best attempts and coming here. What I need is a 10 to 12 sided, ellipsoidal base about 600px/2" long by 300px/1" wide, narrowing to a round, 10-sided top about 225px/0.75" which is about 225-300/0.75-1" off the base and is centered along the shorter axis of the ellipse shape and has one side at the center of the longer axis of the ellipse shape.Either this is a REALLY exact request or everyone's brains will be popping like grapes.Thanks in advance if only just for putting up with my post.
Nevermind this, a friend of mine showed me what I was doing wrong in sketch-up.
