Header file for document

The header file (h-file) of a document provides general information about the object that the document represents, such as the drawing's title and number, and the object's total mass and center of gravity. This ASCII file contains data records in the form of tag–value pairs. Each tag and its value string are separated by one or more space characters or tabs, and the value string is terminated by a semicolon that indicates the end of the record.

sys Water;

Typically, this information is used by displaying it in the title block of the drawing or in the header fields of printed lists. The tags can be used in data requests to refer to the associated value string; data requests can be defined in drawing sheets, label definitions, and ICGDs, to output the desired values to the required location in the required format. The tag names can be freely chosen, as long as they do not conflict with reserved tag names.
