Syllabus
Ruled surfaces – their creation and basic properties, developable and non-developable ruled surfaces.
Helix, creation and properties of helical surfaces, ruled helical surfaces, cyclic helical surfaces.
Other significant surfaces of technical practice (e. g. translational surfaces, pipe surfaces).
Geometry of shadows in various projections.
Use of graphical software for modeling and geometry of shadows.
Annotation
Basic lecture on descriptive geometry devoted to important surfaces of technical practice, their properties, usage in practice, displaying in various projections and surface modeling on computer.
