Surface Thicken error

[Anonymous]

Hello,

I'm trying to thicken this surface model. I originally started with geometry someone else designed in Rhino and have modified it in the Patch environment significantly. I struggled greatly with errors caused by almost tangent and almost coincident lines/points throughout the process, but I finally got it mostly where I want it. I've also tried patching the bottom, using boundary fill to turn it into a solid, and then using shell, but that failed as well. 

Thank you so much for your help!

I am not sure why you'd want to bring over the design for such a simple looking thing from Rhino and then go through the pain of fixing it in the patch environment.

Thickening this is going to be difficult because of the many surface discontinuities that can be seen wit the zebra analysis and because of the sharp edge at the top of the model.
