This work presents new operators for construction of 3D cell complexes. Each cell in a complex is represented with the Augmented Quad-Edge (AQE) data structure. Cells are linked together by the dual structure and form a mesh. This structure stores information about the geometry and topology of a modelled object. Navigation in the mesh is possible using standard AQE operators. A new set of atomic operators was developed to simultaneously construct the Primal and the Dual structures. This allows 3D tetrahedralization as well as the construction of different types of objects, such as buildings composed of multiple rooms and floors.
