Why Do We Need Objects?
Let's assume you have created an exploded view illustration for a spare parts catalog. Now you assign a name to each spare part drawn. You use the spare parts number of the part concerned for the name.
This provides a basis for managing this data in a database. How you can do this will be dealt with later. Let us first take a look at how you can use this data.
You could, for example, write this information to a text file which would then contain a list of all the parts drawn on the illustration. This list could then be loaded into a database which manages your archive. This allows you to search your database for specific terms.
