Relative dimensions are constraints that associate two different nodes in the hierarchical structure. It is also proposed an algorithm to satisfy a set of relati

It focuses on concurrent design support, product modeling, design parameters inheritance and information propogating among different hierarchies of an integrated design process. A prototype of a CACD system for plastic encapsulation mold is implemented at Shanghai Jiao Ton

These schemes are based on the .2/.3-splines, which are embeded in the cubic interpolating .-splines and have 2 and 3 cubic segments by knot-insertion in each span respectively. The local scheme dependent on data points generates span-by-span a . curve with reasonable locali

Each face (patch) of the quadrilateral network has to be assigned a subdivision level (mesh density) first, which is in tern used to assign labels to the vertices of the quadrilateral network. The mesh is genera

We propose to derive such criteria from observed engineering processes and to test these requirements experimentally. We describe the first series of observations that resulted in data, serving as a reference
