Variational Direct Modeling: A framework towards integration of parametric modeling and direct modeling in CAD
Qiang Zou, Hsi-Yung Feng, Shuming Gao
Feature-based parametric modeling is the de facto standard in CAD. Boundary representation-based direct modeling is another CAD paradigm developed recently. They have complementary…
Parametric/direct CAD integration
Qiang Zou
In the history of computer-aided design (CAD), feature-based parametric modeling and boundary representation-based direct modeling are two of the most important CAD paradigms, deve…
A review on geometric constraint solving
Qiang Zou, Zhihong Tang, Hsi-Yung Feng +3
This paper presents a comprehensive review of geometric constraint solving in parametric computer-aided design (CAD), with the major focus on its advances in the last 15 years. Geo…
Length-optimal tool path planning for freeform surfaces with preferred feed directions
Qiang Zou, Charlie C. L. Wang, Hsi-Yung Feng
This paper presents a new method to generate tool paths for machining freeform surfaces represented either as parametric surfaces or as triangular meshes. This method allows for th…
A decision-support method for information inconsistency resolution in direct modeling of CAD models
Qiang Zou, Hsi-Yung Feng
Direct modeling is a very recent CAD paradigm that can provide unprecedented modeling flexibility. It, however, lacks the parametric capability, which is indispensable to modern CA…
A robust direct modeling method for quadric B-rep models based on geometry-topology inconsistency tracking
Qiang Zou, Hsi-Yung Feng
Boundary representation (B-rep) model editing plays an essential role in computer-aided design and motivates the very recent direct modeling paradigm, which features intuitive push…
