When using the meta-properties in 3DVIA that are coming from the Custom Properties in SolidWorks files, be aware how 3DVIA deals with capitalization of the property names.

While SolidWorks and Windows Explorer don’t see the difference between DESCRIPTION, Description, and description (as long as they are all spelled the same), 3DVIA see these as three different properties. Therefore if your BOM only lists DESCRIPTION and some of the actors have one of the other two variations of the word, that cell in the BOM will be blank.  So it is important to verify that the Custom Properties are consistent.
