1. Task 16
Describe the need for document control (such as ensuring that completed models are approved, labelled and stored on a suitable storage medium).

2. Document Control CAD models can be approved in 1 of 2 ways:
Approval can be done digitally – this means that a section of the model properties database is completed by the checker.
Approval may be completed via a paper based approval form which is signed by the checker and filed safely.

3. Labelling CAD Models
Every company has their own system for naming, labelling and storing CAD files.
In each case the models should be named correctly according to the approved system.

4. Storing CAD Models
Models should be filed in folders as specified by company procedures.
Models will generally be stored on the company network server, rather than the local hard drive of designers computers.
Off-site back-up of files should also be done daily in case of fire, flood or theft.
