Research on 3D dimension automatic projection and quick update

Abstract

A dimension classification method that classifies the 3D dimension to sketch dimension, feature dimension and real dimension is proposed for the problem of slow update process when dimension automatic projection. By matching the 3D dimension and the related elements of model, the dimension automatic projection and quick update when projecting 3D model to 2D view is realized in this paper. The dimension classification, association and update mechanism are introduced in details. An application of projecting the 3D dimension of a shell part based on the interface of CAXASOLID is displayed to support the overall approach. Finally, the trends of dimension automatic projection are summarized.
