ROOT Version: 6.16.00-patches from git
Platform: Mac OS
Synopsis: With 6.16.00 when importing a GDML file, all the volumes are placed at the origin instead of in there proper location.
I compare directly the version 6.16.00-patches from git, 6.16/01, against the identically compiled 6.14/09. Both use same compiler (llvm clang-1000.11.45.5), same operating system (Mac OS 10.14.3), same Python version (3.7.2).
With the 6.14/09 version of ROOT, the GDML file imports correctly and renders correctly. I also exported that geometry as a root file. With 6.16/01, if I import the same GDML files, all the volumes are in the wrong place, it looks like they are all translated to the origin. If I open the geometry as root file (exported by 6.14/09 version), the geometry looks fine with either version.
