Hi Bonnie,

The surface cuts are intended for use on a flat surface.

It is best to remove all handles in the segmentation volume prior to generating 
a surface.  There are several modes for editing segmentation voxels that 
include both adding voxels (filing the handle) and removing voxels (essentially 
cutting the handle).

* Use Volume Menu->Segmentation->Find Handles to automatically identify handles 
in the segmentation volume.
* Use Volume Menu->Segmentation->Edit Voxels  to edit segmentation voxels to 
repair handles.
* Use Volume Menu->Segmentation->Topology Report to help verify handles have 
been removed.
* Surface Menu->Topology->Correct Fiducial Surface Topology can remove handles 
from a surface.  However, there is the possibility of undesired changes to the 
surface especially when there are large handles.  

These items may be helpful:
