This is an Open Access article distributed under the terms of the Creative Commons Attribution License Abstract Geometric computing has recently found a new field of applications namely the various geometric problems which lie at the heart of rationalization and construction-aware design processes of freeform architecture. We report on our work in this area dealing with meshes with planar faces and meshes which allow multilayer constructions which is related to discrete surfaces and their curvatures triangles meshes with circle-packing properties which is related to conformal uniformiza-tion and with the paneling problem. We emphasize the combination of numerical optimization and geometric knowledge. 1 Background The time of writing this survey paper coincides with the summing up of a six-year so-called national research network entitled Industrial geometry which was funded by the Austrian Science Fund FWF . By serendipity at the same point in time where the first . students started their work in this project a whole new direction of research in applied geometry turned up meshes and three-dimensional geometric structures which are relevant for rationalization and construction-aware design in freeform architecture. It turned out to be fruitful and rewarding and of course it is also a topic which perfectly fits the heading of Industrial Geometry .
