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

EdgeTolArray

Array of tolerances for edges

VertexTolArray

Array of tolerances for vertices

PointArray

Array of coordinates of vertices (geometry for vertices)

CurveArra1

Array of curves (geometry for edges; 3D curve) and coedges (geometry for coedges; 2D curve)

CurveSurfaceArray1

Array of surfaces that lie on CurveArra1 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 children, 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

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:

• IBody2::CreatePlanarSurface or IBody2::ICreatePlanarSurface

• IBody2::AddProfileArc or IBody2::IAddProfileArc

• IBody2::AddProfileLine or IBody2::IAddProfileLine

• IBody2::CreateRevolutionSurface or IBody2::ICreateRevolutionSurface

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

The topologies array:

The set of arrays:

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.
