That's the point. Try to put your primitives into regions. E.g. create a database with
units m in pyramid.s arb5 0 0 0 0 1 0 1 1 0 1 0 0 0.5 0.5 1 r pyramid.r u pyramid.s g all.g pyramid.r Now try to convert all.g, pyramid.r and pyramid.s. You'll see that the first two are OK. The pyramid.s emits the FAIL message although all three describes the same shape. (The reason for the special meaning of regions is that they describe the base shapes of the geometry model which are not necessarily primitive shapes but build of primitives by boolean operations.)
