oloid model

Hello, I've learned about this really great shape called an Oloid and I was wondering how to make it in ProE. The shape is basically taking two disks of equal dims and perpendicularly intersecting them so they touch each others centers. Then after having the two disks together, you stretch a "skin," like a balloon, over the disks to make it a solid piece. Just look up oloid on google to get pictures. Ploting the disks is pretty easy but I have a hard time getting the "skin" on there, does anyone have any ideas? Thanks, Allen

thats a cool shape! i think i would attempt that by using a skeleton of curves then patching it all together with surfaces from boundaries and useing the tangent boundary constraints so its all nice and smooth. theres probably 20 other ways to do it but that what came to mind first. might be able to do a surface free form and manipulating all those points

This is interesting. I'd post pics but I can't. I tried a variety of ways, and while they LOOKED good, there were some pretty marked differences in the actual surfaces that resulted. I did a one-direction boundary blend using only the end arcs. I did a blend using the end arc and line segment. I did a boundary blend of a quarter section. I did a VSS halfway with a spine that ran in a line from end to end. I revolved surfaces on each end and did a blend between the 2. These ALL resulted in different surfaces, sometimes drastically so, as I suspected. I'm wondering if Pro/E even has the capability of creating a true mathematically-correct oloid. you can probably get really close, but true.......?? Hmmm. Kevin, if you could please post a link to the PDF's you mentioned that'd be awesome. This is interesting though.
