Method of geometric information sharing and parametric consistency maintenance in a collaborative design environment

摘要

A method for sharing geometric information and maintaining parametric consistency amongst different software applications in a collaborative environment is presented. The method is based on geometric information sharing via neutral files, and incorporates Internet based messaging mechanisms amongst applications to maintain the parametric control over the exchanged geometry. In a preferred embodiment the proposed method is applied to Heterogeneous Assembly Modeling (HAM). By means of the presently disclosed method, within the heterogeneous assembly model, the parametric control over part geometry is maintained, even though the parts are imported in the assembly via neutral files originated by other CAD applications.
