I need to know how to draw this in 3d and then import into geomagic designs so I can save as a sldprt file so I can then create a mold cavity with it. It is a triaxial ellipsoid that measures 3.5 X 9.00 I usually use the geomagic program which was formerly alibre to create all my 3d shapes and then use a Boolean function to create mold cavities that I can then use my cam program partmaker to generate gcode. alibre will not create this particular shape exactly the way I want the closest I can get is a parabola slice function which is nothing more than a slice off the top of a bi axial radius. If anyone knows how I can create this in auto cad id much appreciate it. I do not have any experience in drawing off 2d in autocad i use it to generate dxf files that i then import into alibre to extrude and revolve to make the shapes i need..
