Parameters

Type
Type of body to create as defined in swTopology_e
NTopologies
Number of topological entities in the topologies argument
Topologies
Array of topologies (see swTopoEntity_e), one for each topological entity
EdgeToleranceArray
Array of tolerances for edges
VertexToleranceArray
Array of tolerances for vertices
PointArray
Array of coordinates of vertices (geometry for vertices)
CurveArray1
Array of curves (geometry for edges; 3D curve) and coedges (geometry for coedges; 2D curve)
CurveSurfaceArray1
Array of surfaces that lie on CurveArray1 2D curve
CurveArray2
Array of curves (geometry for edges; 3D curve) and array of coedges (geometry for coedges; 2D curve)
CurveSurfaceArray2
Array of surfaces that on lie on CurveArray2 2D curve
SurfaceArray
Array of surfaces (geometry for faces)
NRelations
Number of 1-to-1 relationships between topological entities
Parents
Array of parents, one in each relationship
Children
Array of parents, one in each relationship
Senses
Array of senses in which child is used by parent in the relationship
Option
  • 0 = Default
  • 1 = Repair and simplify body

  • 2 = Simplify body

  • Return Value

    Body

    Remarks

    The CurveArray1 and CurveArray2 must be paired with CurveSurfaceArray1 and CurveSurfaceArray2, respectively. Order is not important. The 2D curve has to be created in the direction of the loop.

    If non-negative values are packed into the EdgeToleranceArray and VertexToleranceArray arrays, then tolerances are applied to the corresponding edges or vertices. These arrays should be the same size as CurveArray1 and PointArray, respectively. Otherwise, a default value of 1.0e-8 (modeler precision) is used.

    NOTE: IModeler::SetInitKnitGapWidth does not affect this method.

    Useful methods for creating geometry for the topological entities are:

    For example, to create a cone, find topological relationships and form relevant arrays. A complete solid cone consists of 8 topological entities:

      • 1 shell

      • 2 faces

      • 3 loops

      • 1 edge

      • 1 vertex

    There are 8 relations:

      • the shell is the parent of 2 faces - 2

      • the planar end face has 1 loop - 1

      • the conical face has 2 loops - 2

      • two loops are each the parent of 1 edge - 2

      • one loop is the parent of 1 vertex 1

    Values in the parents and children arrays correspond to the indices of the topology array.

    Each face or edge created by IModeler::CreateBrepBody3 or IModeler::ICreateBrepBody3 has an associated integer ID that is the same as the index to the input topologies. Use IFace2::GetFaceId or IEdge::GetId to get the associated integer ID.

    Every shell should be a closed shell. Sheet bodies should have additional back faces to form a closed shell. When creating a sheet body, these extra back faces are retained in the result and should be removed using IModeler::DeleteFacesFromSheetBody or IModeler::IDeleteFacesFromSheetBody.
