US Patent:

60631287, May 16, 2000

Filed:

Nov 10, 1997

Appl. No.:

8/966888

Inventors:

Keith Bentley - Glenmore PA
Samuel Wilson - Wilmington DE
Earlin Lutz - West Chester PA
James Bartlett - Elverson PA
John Gooding - Spring City PA

Assignee:

Bentley Systems, Incorporated - Exton PA

International Classification:

G06G 748
G06F 1750

US Classification:

703 6

Abstract:

A computer system for modeling is disclosed, where the computer system has a storage device, first and second platforms, a portable persistent model, and first and second platform-dependent computerized modeling systems (CMS). Each platform is interfaced to the storage device and provides system-dependent services. The first platform has a first type of operating system and a first type of computer hardware including a first memory, and the second platform has a second type of operating system and a second type of computer hardware including a second memory. The model resides in the storage device in a platform-independent format and includes persistent component objects. The first CMS resides in the first platform memory and the second platform-dependent CMS resides in the second platform memory. Each CMS provides CMS services including retrieving the model from the storage device, manipulating the model, changing the model by adding and removing persistent objects, and persistently saving the model to the storage device. Each CMS includes a static kernel and a dynamic framework.
