Tessellation routines seems to present problems for sketches
mixing arcs with Beziers and arcs with arcs.
Attached herein there's an example of correct behavior
(file correct.g) consisting in a sketch composed of closed
beziers and circles that extrudes and converts well to (for
example) STL format:
$ g-stl -o correct.stl correct.g ext
428 triangles written
In addition there's the problematic example mixing arcs
and beziers in a topological correct closed sketch (see incorrect.asc
for details about correctness of vertex linking) that extrudes well on mged
and can be raytraced without problems but makes g-stl complain
about some issue regarding the fact that sketch loop is not closed:
$ g-stl -o incorrect.stl incorrect.g ext
rt_extrude_tess: A loop is not closed in sketch sk
nmg_booltree_leaf_tess(ext): tessellation failure
db_walk_subtree() FAIL on '/ext'
