48-175 Descriptive Geometry
9 units, Carnegie Mellon University
Descriptive geometry deals with solving problems in threedimensional geometry through working with twodimensional planes using basic mechanical tools. Descriptive geometry deals with physical space, the kind that one is used to since birth. Things one can see around us have geometry and even things that one cannot see, also have geometry. All these things concern geometric objects almost always in relationshipsthat is, next to, above, below, intersecting with, occluding, hidden by and so onto one another that sometimes requires us to make sense of it allin other words, when we try to solve geometric problems albeit in architecture, engineering, or the sciences. In fact, descriptive geometry has proved itself to be practically useful it has been one of the more important factors in the design of scientific apparatus, engineering systems and architectural structuresit is the basis of modern geometrical computing. Descriptive geometry is constructivemeaning, one uses conventional mechanical drawing tools namely, compass, ruler, protractor, divider, triangles, etc., to construct solutions to geometric problems. This course specifically revolves around the historical techniques for manually solving threedimensional geometry problems.
