1. Which is the primary reason why is it recommended that the filename is changed every so often (e.g. once every two hours)?
If the file were to corrupt, there will be less re-work
With more versions of the file, it makes it easier to locate at least one version of the file
It is necessary to roll back / restore an earlier version of the file
2. For what reason is it recommended that version numbers be saved as decimals?
In larger models, the file version number may become unnecessarily large otherwise.
Each 0.01 is an iterative change (e.g. signifying so many hours since the last file version), whereas a change of integer (e.g. 1.03 to 2.01) would indicate a significant milestone or step change has been achieved.
If the version number is too high when it circulates, it gives the information that the modeler didn’t really know what they were doing.
3. Which of the following attributes was not included in the filename recommendations for version control?
