Automatic Recognition of Features from Cad Models for Mesh Generation

Automatic recognition of features from CAD models is one of the key technologies for mesh generation. This paper studies the algorithm for automatic recognition of features from CAD models in STL data format. Firstly, a new STL data file with topological connection is constructed for the calculation. Secondly, the coplanar relationships among all the triangle facets are constructed initially. T...

A hybrid method for feature recognition in CAD models

Automatic Feature Recognition (AFR) techniques applied to 3D solid models are an important tool for achieving a true integration of Computer-Aided Design (CAD) and Computer-Aided Manufacturing (CAM) processes. In particular, AFR systems allow the identification in CAD models of high-level geometrical entities, features that are semantically significant for manufacturing operations. However, the...

Feature suppression based CAD mesh model simplification

According to the characteristics of CAD mesh model and the requirements of engineering applications, we propose a novel method of simplifying CAD mesh model. First, the model is segmented using an improved watershed segmentation algorithm, and the region-level representation required by feature recognition is set up. Second, the form features needing to be suppressed are extracted through featu...
