you get a cube with a void inside. The two have come about because of the way CAD
has developed; both have strengths and weakness, but most people will be using solid
models at the start.

8.6.1 Cloud Computing
A modern trend is to use cloud computing. For the designer using a CAD system this is
invaluable. In the past keeping track of the most up-to-date design was a nightmare. Cloud
servers have made this a thing of the past. A central server holds the information securely and
it synchronizes when anything changes. Therefore the cloud server always holds the most up-
to-date information. Even more importantly, it looks after the backup too! If you have ever
lost any work due to forgetting to back up you will know how valuable this is.
