My colider Mesh Issue

[Rohan_Saxena]

So when I applied the unsubdivide, the object was fine, except for one side of it. here are the screenshot

That whole side of the mesh was warped and i couldn’t create the flat base. Help?

I’m assuming i went wrong somewhere in the spin part? I did remove doubles but… I don’t know. Anybody else facing this issue?

So i went back to removing doubles,
and got a pretty funky, but workable base. I basically selected the edges of the circle (screenshot below)

and then worked my way inward for the two (sort of) circles

Im not sure how feasable this solution is…

any comments/advice?
