CURVES

Curves are representatives of the MbSpaceItem three-dimensional geometric objects family. All curves have a common parent class MbCurve3D. The C3D geometric kernel uses curves that are constructed using analytical functions, from a set of points, based on curves, and based on surfaces. Curves are used to construct surfaces as well as auxiliary elements of the geometric model. We’ll use bold Latin letters to designate radius vectors of points, and matrices in three-dimensional space.
