Sorry for my ignorance about GDML, XML etc. While importing a gdml file with the gGeomanager, I get the following error
Error: Unsupported GDML Tag Used :multiUnion. Please Check Geometry/Schema.
Error: Unsupported GDML Tag Used :multiUnionNode. Please Check Geometry/Schema.
Error: Unsupported GDML Tag Used :solid. Please Check Geometry/Schema.
Are these objects not supported by ROOT? Or what am I missing?
