# Description

Metrics assembler can generate errors if the attribute that should be
corrected is part of a scene graph instancing. If scene graph instancing
is used and the units don't match, it can't be fixed. For the lift teddy
bear example, we disable the metrics assembler to avoid hitting such
errors.
