1 A User Interface Model and Tools for Geometric DesignPoor user interfaces discourage potential users from effectively utilizing the design capabilities of geometric modeling systems. Because of the complex nature of the underlying representations in such systems, a well structured user interface model, as well as useful and intuitive design tools, are...user interface; computer systems; computer-aided design
2 Approximating data with parametric B-splines for computer aided designThis thesis addresses some of the difficulties that can be encountered when approximation is used as a design tool. In many cases, it is most intuitive for a designer to specify points on or near a desired contour, and approximate them with a curve. Merely computing some approximation to a set of da...computer graphics; computer-aided design; approximation theory; B-splines1985-12
3 Modelling complex objects with generalized sweepsRecently, constructive solid geometry (CSG) techniques have been generalized to include set operations on certain sculptured surface solid models. This advancement has reemphasized the need for modelling techniques that create vasod objects. The definition of a valid object is somewhat cumbersome in...computer-aided design; computer graphics1985-12
4 Numerical Control Milling Machine Toolpath Generation for Regions Bounded by Free Form Curves and SurfacesThe search for strategies and methods to automatically generate toolpaths for Numerical Control (NC) machines from mechanical parts modeled by computer aided solid design systems has met with only limited success to date, mainly in applications to simplified models. Problems that occur when the exis...computer graphics; computer-aided design; numerical control machines; toolpath generation1989-06
5 Sketching with constraintsThe goal of this thesis is to provide a simple and intuitive user interface to a Computer Aided Design (CAD) system. A simple modeling system was built to demonstrate the utility of the ideas presented here. There are three main parts to this system. The first part is the interpretation of sketched ...user interfaces; computer systems; computer-aided design; CAD system1994-06
