II. Multiple Platforms and Application Considerations

A. Platforms

All CADD data shall be supplied to NCS in the latest version of Intergraph

Corporation's, MicroStation CADD software. The contractor shall be

responsible for ensuring that all files (base files, reference files, cell libraries)

are compatible (without translation) with the NCS's CADD system,

MicroStation 32 or MicroStation PC.

The three (3) basic types of platforms which now operate Intergraph

proprietary software are the Intergraph UNIX work stations, Microsoft

Windows NT, and MS-DOS compatible personal computers (PC's). These

platforms operate with either MicroStation 32 (UNIX), or MicroStation PC

(DOS). Regardless of the platform, the Intergraph file format is the same.

This binary compatibility means that reference files and font and cell libraries

can be directly transferred from each system without translation. The

software for each of these platforms is not identical. File naming conventions

must address the limitations of DOS. MS-DOS will accept file names with a

maximum length of eight characters plus the three-character extension. The

extension for Intergraph design files is .dgn (e.g., filename.dgn). Most

importantly, file naming conventions should remain consistent within NCS,

and the three-character file name extensions should be as shown from the

following chart:
