BRepOffsetAPI_MakeEvolved Class Reference

Describes functions to build evolved shapes. An evolved shape is built from a planar spine (face or wire) and a profile (wire). The evolved shape is the unlooped sweep (pipe) of the profile along the spine. Self-intersections are removed. A MakeEvolved object provides a framework for: More...

Detailed Description

Describes functions to build evolved shapes. An evolved shape is built from a planar spine (face or wire) and a profile (wire). The evolved shape is the unlooped sweep (pipe) of the profile along the spine. Self-intersections are removed. A MakeEvolved object provides a framework for:

The profile is defined in a Referential R. The position of the profile at the current point of the spine is given by confusing R and the local referential given by ( D0, D1 and the normal of the Spine)

If the Boolean <AxeProf> is true, R is O,X,Y,Z else R is defined as the local refential at the nearest point of the profil to the spine.

if <Solid> is TRUE the Shape result is completed to be a solid or a compound of solids.

These constructors construct an evolved shape by sweeping the profile Profile along the spine Spine. The profile is defined in a coordinate system R. The coordinate system is determined by AxeProf:

  • if AxeProf is true, R is the global coordinate system,
  • if AxeProf is false, R is computed so that:
  • its origin is given by the point on the spine which is closest to the profile,
  • its "X Axis" is given by the tangent to the spine at this point, and
  • its "Z Axis" is the normal to the plane which contains the spine. The position of the profile at the current point of the spine is given by making R coincident with the local coordinate system given by the current point, the tangent vector and the normal to the spine. Join defines the type of pipe generated by the salient vertices of the spine. The default type is GeomAbs_Arc where the vertices generate revolved pipes about the axis passing along the vertex and the normal to the plane of the spine. At present, this is the only construction type implemented.
