Standard_EXPORT BRepOffsetAPI_MakeOffsetShape();
//! Constructs a shape parallel to the shape S, where <br>
//! S may be a face, a shell, a solid or a compound of these shape kinds; <br>
//! Offset is the offset value. The offset shape is constructed: <br>
//! - outside S, if Offset is positive, <br>
//! - inside S, if Offset is negative; <br>
//! Tol defines the coincidence tolerance criterion for generated shapes; <br>
//! Mode defines the construction type of parallels <br>
//! applied to the free edges of shape S; currently, only one <br>
//! construction type is implemented, namely the one where the free <br>
//! edges do not generate parallels; this corresponds to the default <br>
//! value BRepOffset_Skin; <br>
//! Intersection specifies how the algorithm must work in <br>
//! order to limit the parallels to two adjacent shapes: <br>
//! - if Intersection is false (default value), the intersection <br>
//! is calculated with the parallels to the two adjacent shapes, <br>
//! - if Intersection is true, the intersection is calculated by <br>
//! taking all generated parallels into account; this computation method is <br>
//! more general as it avoids some self-intersections generated in the <br>
//! offset shape from features of small dimensions on shape S, however this <br>
//! method has not been completely implemented and therefore is not <br>
//! recommended for use; <br>
//! SelfInter tells the algorithm whether a computation <br>
//! to eliminate self-intersections must be applied to the resulting <br>
//! shape; however, as this functionality is not yet <br>
//! implemented, it is recommended to use the default value (false); <br>
//! Join defines how to fill the holes that may appear between <br>
//! parallels to the two adjacent faces. It may take values <br>
//! GeomAbs_Arc or GeomAbs_Intersection: <br>
//! - if Join is equal to GeomAbs_Arc, then pipes are generated <br>
//! between two free edges of two adjacent parallels, <br>
//! and spheres are generated on "images" of vertices; <br>
//! it is the default value, <br>
//! - if Join is equal to GeomAbs_Intersection, then the parallels to the <br>
//! two adjacent faces are enlarged and intersected, <br>
//! so that there are no free edges on parallels to faces. <br>
//! Warnings <br>
//! 1. All the faces of the shape S should be based on the surfaces <br>
//! with continuity at least C1. <br>
//! 2. The offset value should be sufficiently small to avoid <br>
//! self-intersections in resulting shape. Otherwise these <br>
//! self-intersections may appear inside an offset face if its <br>
//! initial surface is not plane or sphere or cylinder, also some <br>
//! non-adjacent offset faces may intersect each other. Also, some <br>
//! offset surfaces may "turn inside out". <br>
//! 3. The algorithm may fail if the shape S contains vertices where <br>
//! more than 3 edges converge. <br>
//! 4. Since 3d-offset algorithm involves intersection of surfaces, <br>
//! it is under limitations of surface intersection algorithm. <br>
//! 5. A result cannot be generated if the underlying geometry of S is <br>
//! BSpline with continuity C0. <br>
//! Exceptions <br>
//! Geom_UndefinedDerivative if the underlying <br>
//! geometry of S is BSpline with continuity C0. <br>
