There are several possibilites.

The necessary creation steps are preparation of parts lists and illustrations, automatic generation of links, and creation of the catalog pages.  (Also, the execution of a database solution would be possible.)

Preparation of the parts lists
In essence, the text component of a spare parts catalog consists of parts lists in table form. For each illustration exists exactly one parts list. If the data is administrated in a database, a series of appropriate tables can be created without much effort and then later examined. This can be done through a direct database connection or through text files.

Preparation of the illustrations
As already explained in detail, the illustrations could be prepared automatically if text elements are converted into graphical objects with hotspot attributes.

Automatic generation of links
The generation of links is the core of automation. The illustrations correlate with graphical objects and are linked with the appropriate parts list entries. At the same time a consistency check can be conducted, revealing if any position numbers or parts list entries are missing. The information from the illustration is compared with the parts lists. From this, the information needed for the links is derived. When the catalog pages are created, the links are created with the required syntax.

Generation of the catalog pages
The single catalog pages are written in HTML format and are generated from the available information. The links are realized automatically via URLs and JavaScript. Thus, an "intelligent" graphics viewer, such as IsoView, can be addressed.
