SURFACES ======== .. _SURFACES_: Surfaces belong to the family of :ref:`MbSpaceItem ` three-dimensional geometric objects. Surfaces play a major role in construction of a geometric model and are used to describe smooth sections of geometric form for simulated objects. Surfaces are constructed using analytical functions based on a set of points, as well as based on curves and based on surfaces. We will use **bold** Roman font to designate vectors, radius vectors of points, and matrices in three-dimensional space. .. toctree:: :maxdepth: 1 subsections/EN/MbSurface_Surface subsections/EN/MbPlane_Plane subsections/EN/MbCylinderSurface_Cylindrical_Surface subsections/EN/MbConeSurface_Conical_Surface subsections/EN/MbSphereSurface_Spherical_Surface subsections/EN/MbTorusSurface_Toroidal_Surface subsections/EN/MbExtrusionSurface_Extrusion_Surface subsections/EN/MbRevolutionSurface_Revolution_Surface subsections/EN/MbExpansionSurface_Motion_Surface subsections/EN/MbSpiralSurface_Spiral_Surface subsections/EN/MbEvolutionSurface_Swept_Surface subsections/EN/MbExactionSurface_Swept_Surface_with_Adaptation subsections/EN/MbSectorSurface_Sectorial_Surface subsections/EN/MbRuledSurface_Ruled_Surface subsections/EN/MbLoftedSurface_Surface_Based_on_a_Family_of_Curves subsections/EN/MbElevationSurface_Surface_Based_on_a_Family_of_Curves_And_a_Guiding_Curve subsections/EN/MbCornerSurface_Surface_Based_on_Three_Curves subsections/EN/MbCoverSurface_Coons_Surface subsections/EN/MbCoonsPatchSurface_Coons_Surface subsections/EN/MbMeshSurface_Surface_Based_on_a_Network_of_Curves subsections/EN/MbJoinSurface_Joint_Surface subsections/EN/MbSplineSurface_NURBS_Surface subsections/EN/MbOffsetSurface_Equidistant_Surface subsections/EN/MbChamferSurface_Chamfer_Surface subsections/EN/MbFilletSurface_Fillet_Surface subsections/EN/MbChannelSurface_Fillet_Surface subsections/EN/MbCurveBoundedSurface_Surface_with_Arbitrary_Borders
