Stitched surfaces to face

[bravaiser]

Greetings everyone.

Is it possible to create a solid from a sttiched surface. I am uploaidng the file, this is the Standford Bunny. I want to extract the back. The file is made of multiple surfaces. I stitch them together. When I apply boundary patch, the result is not the correct curvature need it. How can I create a solid body out of this surfaces?

Thank you

Hmm. I found a SLDPRT file here:

https://grabcad.com/library/stanford-bunny-solid-model/files/bunny.SLDPRT

I could import it as a solid without problems into 2014.

Perhaps a better start for you.
