# How to create a solid part that tapers from one oval to a second oval with different dimensions?

Member Posts: 5
The ovals on the sketch plane would share the same origin, but have a different dimension for both the major and minor axes.
For example
Oval 1: Major axis 8, minor axis 6
Oval 2: Major Axis 10, minor axis 7
Assume the part thickness (along the extrusion axis) is 10mm.

This might be thought of as a tapered cylinder, or truncated and tapered cone, where the taper amount is different in the x and y dimensions, where z is the extrusion axis. If this can be performed with draft, what are the steps to perform?

Thank you.

Hi, I would always use the loft feature tool for this type of geometry.  You can find the help page here.  But in short you would create 2 planes separated by the thickness of the part and create a different oval sketch on each plane.  Then loft between them.  If you get wacky results the best thing to do is usually use the match vertices box in the loft dialog.  Hope that helps.
