SurfaceTrimSurface Method

Trims a surface with the specified cutting surfaces (curves). A surface can be trimmed by other surfaces or curves. When curves are used, the actual trimming boundary is formed by projecting the curves onto the surface, so the additional information of projection directions needs to be provided.

Parameters

blankSurfaceId ObjectId: [in] Surface to be trimmed.
toolSurfaceIds ObjectIdCollection: [in] Array of the cutting entity's IDs. Bodies of the specified entities are used to trim the specified surface.
toolCurveIds ObjectIdCollection: [in] Array of the cutting curve's IDs. The specified surface is trimmed by projecting curves to it.
projVectors Vector3dCollection: [in] Array of projection directions for each cutting curve.
pickPoint Point3d: [in] Pick point that specifies which area of the specified surface must be trimmed.
viewVector Vector3d: [in] Vector representing the view direction for creating a ray starting from the pick point.
bAutoExtend Boolean: [in] If true, then when a tool body consists of a single face with analytic geometry, the underlying geometry is extended as much as possible to make sure the surface is trimmed.
associativeEnabled Boolean: [in] Specifies whether the surface trimming operation is associative.
