[x3d-public] possible bug in X3D file, or X3D Object model, rotation and translation are not defined for CADFace (but possibly inherited??? and missing from sub node), thus have no local type and cannot be converted to array.

Basically not wanting transformsin CADFace is about the same reason as 
for HAnim, where it is discouraged to use transforms and scales for 
Joints and and Segment geometry. If animated, the scales and 
transforms may not actually operated as expected.

Thanks,
Joe
