thanks for cheking it out james. ill do a re-install or talk with
jouney ed. i have no problems with boundry surfaces. fyi - the error is
"cross curves not connected with same curvature" or whatever. i gather
for you that doesnt show up.
as far as the part, (top of a cowling) the C.0.S. will have a similar
C.O.S. on the bottom half (they both need to have the same profile in
the top view, hence they need to be projected onto the same surface).
anyway i'v tried a lot simpler scenarios with same result.
