AutoTRAX handles 3 different types of files.
Projects contain schematics, text documents and a PCB and represent the design for your PCB.
Part files contain schematic symbols, text documents and a footprint (land pattern) that contains all the information needed to define the abstract schematic representation for a part together with the footprint required for the PCB and the 3D solid model for the part.
Parts are defined parametrically; this allow a single part to be quickly and easily modified into a different part type. The parametric models define how to create a complete part from only a few simple parameters.
Artwork files contain schematic that do not have any electrical content, such as parts and wires. They are used for creating library artwork to be used in project and part files. They can also be used for any other drawing purposes, as AutoTRAX's powerful graphics allows you to graphically design engineering drawings.
