The data structure behind Gears

Every component defined in the User Interface has behind him some data files which contain properties and parameters related to the component itself. These files are placed in the folder of the standard rule. The main files associated to the family of components are the followings: Main_NAME of Comp.ini and TableNAME.uni

Every record contains these fields:

• TableName-> File containing the data values useful to build the component
• Description -> Description of the Standard Rule
• MaterialFile -> Default materials allowed for this kind of component
• CodConf -> Configuration of Code
• and other Fields specific for each components

For example, this is the structure of a Main_Spurs.ini file

#TableName	 | Description                      | Material      | CodeConf	| Density
tb_Spur1.uni | Ruote dentate cil. mozzo laterale| C 45 UNI 7845	| RDM<Z><M>	| 7.88
tb_Spur2.uni | Ruote dentate cil.			    | C 40 UNI 7845	| RD<Z><M>	| 7.88
tb_Spur3.uni | Ruote dentate cil. in ghisa		| G 20 UNI 5007	| RDG<Z><M>	| 7.0

Under each section it is possible to place several records; every record refers to a particular rule.

The TableNAME.uni files, contain the fields of the standard values related to gears normative; the structure of the files are self-explaining.
