Surface Problem

Did you try the suggested actions shown in the error message?

Recommended actions:
Make a quilt from good surfaces, offset the quilt make patches over missing surfaces.

Copy all of the surfaces that can be offset and exclude the problem surfaces flagged by the tool. You will then have an open quilt at the offset value which you would then manually close the holes left in the offset.

You can try the approximate offset option which may offset all of the surfaces.
