According to the BGLCOMP documentation, a Vertex may be defined either by lat/lon or BiasX/Biasz, however the schema does not allow BiasX/BiasZ. Is there a modification to the schema which will allow BiasX/BiasZ in a Vertex statement?George

Hi George,No, doesn't seem to work here either. I must say I never tried it before, because placing all your objects with lat/lon seems a lot better to me than using the old meters again.That only reminds me of the trouble of getting two polygons with different refpoints to allign correct, with lat/lon that is much easier.It seems SGX also uses the lat/lon option only.
