Notes on Saving Flexible Bodies
When saving the flexible body created in ViewFlex, make sure you select a name that does not interfere with other files in the current working directory, or the template-based product's default writable database, which are linked to different models or to a different template. Changing the content of the modal neutral file (MNF), such as changing the position of an attachment or the number of attachments, overwrites the existing MNF, making the previous model or template unusable.
