8.6.2 Document and Revision Management
Most modern CAD systems also come with built-in revision management. Once again, this
is often in conjunction with a secure server (some of them use the cloud servers above).
Most programs force you to keep revision histories up to date. Figure 8.10 illustrates the key
components of an engineering drawing, but you should refer to the relevant standard(s); some
are given in Table 8.5 for guidance.

8.6.3 Collaboration
As I stated earlier, collaboration is easy once you have gone digital. Most modern CAD
systems come with interfaces, such as EDrawings ® , that enable you to have discussions
