v3.0
現在の SubComponent
の特定のコンポーネントタイプと一致するコレクションオブジェクトを戻します。たとえば、次のようになります。
- VertexCollection は Vertex コンポーネントと一致(PolygonMesh 上)
- ControlPointCollection
は ControlPoint コンポーネントと一致(NurbsCurveList および NurbsSurfaceMesh 上)
- EdgeCollection は Edge コンポーネントと一致(PolygonMesh 上)
- PolygonFaceCollection は
PolygonFace コンポーネントと一致
- NurbsSurfaceCollection
はサブサーフェイス(NurbsSurface)コンポーネントと一致(NurbsSurfaceMesh 上)
注: 同等のコンポーネント コレクションがない場合、空の XSICollection が戻されます(境界またはノットが NurbsSurfaceMesh 上で選択されている場合など)。
/*
This example demonstrates how to query the type of component
that is currently selected. This can be useful if you are
writing a tool that operates only on a specific subcomponent
and you are checking to make sure the correct type of
subcomponent has been selected by the user.
