TOPOLOGICAL OBJECTS

Geometric properties that don’t depend on quantitative characteristics (lengths and angles) and that reflect continuous relationship of object elements and its environment are called topological properties. Topological objects of C3D geometric kernel also describe geometrical properties of the object that depend on quantitative characteristics, as well as geometrical properties that reflect continuous relationship of the object with the neighboring elements. Topological objects are constructed based on surfaces, curves and points by adding to their data, properties, and methods new data, properties, and methods that reflect connections of the object with its environment.
