Aim: Geometric modelling is an important part of every design process. This course enables the participants to use CAD-systems for modelling complex geometric objects and suggests geometric solutions to technical problems. Furthermore, the participants obtain a basic knowledge of descriptive geometry and improve their spatial perception.
The course addresses students with interests in advanced geometric modelling in construction, design, multimedia (VRML), scientific visualization etc.

Contents: Geometric analysis and modelling of geometric objects (primitive definitions, sweeping, transformations, boolean operations). Construction of: Primitives, curved surfaces, planar cuts; Space curves, osculation planes, tangent surfaces, Meusnier's sentence, the Projective sentences; Geodetic curves; Helixes, direction cones, helicoids; Sculptured surfaces (Bezier, B-spline, NURBS). Intersection between curved surfaces. The cutting plane and cutting sphere method, the tangent plane and normal plane method. Development. Visualization of geometric models in well-known projections like dimetric projection. Methods for solving important geometric construction problems. The exercises concentrate especially on transforming the theory to practical geometric constructions methods. The 2D CAD system AutoCAD and the 3D solid modelling system Euclid are used during the exercises.
