I am checking the mass properties on an assembly with over 200 components. I get a message that "One of the components requires updating. This may cause the mass properties calculation to be out of date" Is there any way of determining which component may be the problem? Otherwise, it is a fairly useless message. Kind of like saying "your results may be right, or may be wrong, but you'll never really know". If anyone knows of a way to track down the offending component, I would appreciate the help. Thanks.
