Just taking a second to recant that last sentence. I was still using
Cubit 13.1 today. The enumerator seems to be alright when using
Cubit 14.<br>

Evan, <br>
<br>
Spot on. We got it working after adjusting the cubit flag to
TORUS_SURFACE_TYPE. <br>
<br>
Seems like this is a problem from 13.1 on as I had the same issue
in Cubit 14.... <br>

reproduced your problem using a version of CGM that I
built on Cubit13.1. After some experimentation, I think
that the problem is that the GeometryType is off by one in
CGMA from what the Cubit library expects. I got
successful RefFaces when passing arguments
CONE_SURFACE_TYPE (which I am guessing is interpreted as
the one-later enum value PLANE_SURFACE_TYPE) and
TORUS_SURFACE_TYPE (which I am guessing is interpreted as
the one-later enum value BEST_FIT_SURFACE_TYPE).<o:p></o:p></span></p>

things you could try would be giving more than two edges

the end vertex of one edge is the beginning vertex of the
next. I planned to try these, but my only successful
build of CGM with acis so far is a cmake build, and I’m
still a novice in the cmake build system, so I didn’t get
far enough to reproduce the problem. What version are you

The error message seems to indicate it's trying to
