Detailed Description

Creates B-Rep shapes using various feature modeling techniques.

Provides static methods to construct higher-level B-Rep shapes from input B-Rep shapes using various solid, sheet or wireframe modeling techniques such as extrusion and rotation.

The resulting shape type depends on the type of the input shape and is described in the following table:

Input type	Resulting type
Vertex	Edge
Edge	Face
Wire	Shell
Face	Solid

The following table demonstrates supported operations:

CreateExtrusion()	Extruding a Wire into a Shell
CreateRevolution()	Creation of a solid by revolving a face

CreateExtrusion()

ModelData_Shape cadex::ModelAlgo_BRepFeatures::CreateExtrusion ( const ModelData_Shape &  theShape, const ModelData_Vector &  theVec  )

static

Creates an extrusion body.

Creates an extrusion body obtained after extrusion of base shape theShape along vector theVec.

Examples

modeling/assembly/Program.cs, and modeling/brepfeatures/Program.cs.

CreateRevolution()

ModelData_Shape cadex::ModelAlgo_BRepFeatures::CreateRevolution ( const ModelData_Shape &  theShape, const ModelData_Axis1Placement &  theAxis, double  theAngle = 2 * M_PI  )

static

Creates a revolution body.

Creates a revolution body by rotating a base shape theShape around direction of axis theAxis by an angle of theAngle.

The result is a topology with a higher dimension :

• Vertex -> Edge
• Edge -> Face
• Wire -> Shell
• Face -> Solid

theAngle limits the revolution body along the rotation angle. theAngle must be in the range (0, 2 * PI].

Note

The basis topology must not contain shells, solids, body or bodylist.
