Hi,

I'm trying to specify a Parameterization_mesh_patch_3 on a mesh, but after specifying a closed loop of vertices, I am getting an unexpected number of facets being included in the patch. Here is an image to illustrate:

The white dots are the vertices I've specified, and I would expect that the 9 enclosed facets form the patch, but there are actually 18 facets in total, including the one in red.

Before this, I tried to make a patch that exported a single facet by specifying a seam that included 3 vertices of a facet in clockwise order. I would expect 1 facet in the patch but for the mesh I used, I got a patch with 4 facets.

I'm not sure what might be wrong, but I wonder if anyone has any ideas?
