Filed:

Jan 15, 2009

Appl. No.:

12/354290

Inventors:

Olivier Zegdoun - Tyngsborough MA, US
Bruce W. Holway - Brewster MA, US
Amit Mandloi - Acton MA, US
Adarsh Krishnamurthy - Berkeley CA, US

Assignee:

Dassault Systems SolidWorks Corporation - Waltham MA

International Classification:

G06T 17/00

US Classification:

345420, 345421, 345422, 345423

Abstract:

A computer-implemented method and system reduces size of a data structure of a computer-aided design (CAD) model. Given a CAD model formed of a plurality of modeling elements, the method and system provide one or more geometric entities defining modeling elements of the CAD model. The geometric entities have corresponding graphical entities configured to display the CAD model. For each modeling element, the method and system determine visibility of the modeling element and produce a reduced data structure by storing in the structure graphic data representing the graphical entities and geometric data of only certain ones of the geometric entities determined as a function of visibility of the corresponding modeling elements.

International Classification:

G06F 9/44

Abstract:

Creating a reference to data used to construct a computer-aided design model includes storing model data with tracking data, where the tracking data identifies the model data. A reference is created and the tracking data is associated with the reference to enable the reference to refer to the model data. A modeling operation is executed, which retrieves the tracking data associated with the reference, traverses a data structure defining the computer-aided design model while attempting to match the tracking data associated with the reference to the tracking data stored with the model data, and returns geometric data stored in the model data.
