the one I drew is probably not close.
the pic is a fishing lure that weighs 3/16 oz. I need to draw one that weighs 1/2 oz. what i usually do is draw the 3/16 and then scale it up to the 1/2 oz.
It needs to be close in size because lead is very dense and it doesn't take much to change the weight.
Next I think I will try to draw this as slices from front to back and then loft. I always have trouble with the ends when drawing these kinds of parts.

I've attached the 3dm file if that helps.

Is this drawing for rendering purposes, or will it be used to machine a mold? The answer may dictate the best approach to take.

it is for a mold.

hey thanks for the help.

I'm not the machining expert here, but I think Rail Revolve is going to give you the simplest geometry.

1) Draw profile curve. 2) Rail Revolve. 3) Boolean diff with straight line. 4) Fillet to create rounded bottom edges.

The trick to prevent the pinching shown in your example is to insure the end points of the profile curve are tangent. If you want to be sure, Show Points, select a pair of points, and use the Horizontal Alignment tool to line them up as shown in red. File is attached.
