Have you used assembly plugins like Assembly2, 3, 4 and A2plus?
RobotCreator Workbench cannot read those parametric object now.

More detail, it is caused from parent and children object parsing.
obj.TypeId == 'PartDesign::Body' in bodyFromPad() may be worse.
It needs to fix the object parsing function to handle parametric information such assembly plugins.
