Its The *gp* package defines the basic geometric entities used for algebraic calculation and basic analytical geometry in 2d & 3d space. It also provides basic transformations such as identity, rotation, translation, mirroring, scale transformations, combinations of transformations, etc. Entities are handled by value. -Please, note that gp curves and surfaces are analytic: there is no parameterization and no orientation on gp entities, i.e. these entities do not provide functions which work with these properties. +Note that gp curves and surfaces are analytic: there is no parameterization and no orientation on gp entities, i.e. these entities do not provide functions which work with these properties. If you need, you may use more evolved data structures provided by Geom (in 3D space) and Geom2d (in the plane). However, the definition of gp entities is identical to the one of equivalent Geom and Geom2d entities, and they are located in the plane or in space with the same kind of positioning systems. They implicitly contain the orientation, which they express on the Geom and Geom2d entities, and they induce the definition of their parameterization.
