OdDbSurface Methods

	Name	Description
	acisIn	Reads the ACIS data for this entity from the specified StreamBuf object, or reads an array of ACIS solids from the specified file.
	acisOut	Writes the ACIS data of this entity to the specified StreamBuf object, or writes the specified ACIS solids to the specified file.
	body	Returns the current modeler geometry.
	booleanIntersect	This is the overview for the booleanIntersect method overload.
	booleanSubtract	This is the overview for the booleanSubtract method overload.
	booleanUnion	Performs a Boolean union operation with two surfaces: this one and another specified surface.
	brep	Returns the boundary representation of the 3D solid entity.
	chamferEdges	Creates associative chamfers at the specified edges of the surface.
	convertToNurbSurface	Converts the surface to nurb surfaces.
	convertToRegion	Creates region (OdDbRegion class) entities for each face of the surface.
	createExtendSurface	This method is not implemented.
	createFilletSurface	This is the overview for the createFilletSurface method overload.
	createFrom	Creates an extruded surface from a 2D entity with thickness or a planar surface from a closed curve or region.
	createInterferenceObjects	Creates new entities that represent the result of interference between the surface and specified entity. Created entities are appended to the specified array.
	createOffsetSurface	This is the overview for the createOffsetSurface method overload.
	createSectionObjects	Intersects the specified plane with the surface and stores the result of the intersection in an array.
	decomposeForSave	Determines the behavior for custom objects when saving to .dwg or .dxf file.
	dwgInFields	Reads the .dwg file data of this object.
	dwgOutFields	Writes the .dwg file data of this object.
	dxfInFields	Reads the DXF data of this object.
	dxfOutFields	Writes the DXF data of this object.
	extendEdges	This method is not implemented.
	filletEdges	Creates rounded fillets along the specified edges of the surface.
	getArea	Calculates the total surface area.
	getFaceMesh	Returns a mesh for a face.
	getPerimeter	Returns the current perimeter value of the surface.
	getSubentColor	Retrieves the color of a given subentity.
	getSubentMaterial	Retrieves the material of a given subentity.
	getSubentMaterialMapper	Retrieves the material mapper of a given subentity.
	imprintEntity	Intersects the specified entity with the surface and imprints the intersection graph onto the surface. In the case of creating a closed loop of edges, a new face is created. In the case of creating an open loop of edges, it can be added as a spur to an existing loop on a face or as a slit in the face.
	internalSubentId	For internal use only.
	internalSubentPtr	For internal use only.
	isNull	Returns true if and only if there is no ACIS model associated with this entity.
	numChanges	Returns the number of changes occurred since the solid's creation.
	projectOnToSurface	Creates entities by projecting the specified entity along the projection direction to the surface.
	rayTest	Creates a ray which starts from a specified point and has a specified direction.
	saveAs	Creates a geometric representation of the entity for saving proxy graphics or converting to previous formats.
	setBody	Directly sets the contained modeler geometry of this entity.
	setSubentColor	Sets the color of a given subentity.
	setSubentMaterial	Sets the material of a given subentity.
	setSubentMaterialMapper	Sets the material mapper of a given subentity.
	setUIsolineDensity	Sets the number of isolines in the U direction of the surface, displayed in wireframe mode for visualization.
	setVIsolineDensity	Sets the number of isolines in the V direction of the surface, displayed in wireframe mode for visualization.
	sliceByPlane	Slices the surface with the specified plane and sets the surface to be the portion on the positive normal side plane.
	sliceBySurface	Slices the surface with the specified surface.
	subClose	Called as the first operation as this object is being closed, for database -resident objects only.
	subExplode	Explodes this entity into a set of simpler entities. Entities resulting from the explosion are appended to the specified array.
	subGetClassID	Retrieves the class information.
	subGetGeomExtents	Calculates geometrical extents of this surface.
	subGetGsMarkersAtSubentPath	Gets all graphic system markers by subentity paths.
	subGetSubentPathsAtGsMarker	Gets all subentity paths by a graphic system marker.
	subGetTransformedCopy	Retrieves the copied version of this surface transformed by the specified transformation matrix.
	subHandOverTo	Called as the first operation of the handOverTo function.
	subSetAttributes	Sets the values of this object's subentity traits, and returns with the calling object's subentity traits.
	subSubentPtr	Creates a copy of a subentity.
	subTransformBy	Applies the specified 3D transformation matrix to this entity. Only available if transformation is uniform.
	subViewportDraw	Takes a pointer to an OdGiViewportDraw object and builds the view — a specific representation of an entity.
	subWorldDraw	Creates a viewport-independent geometric representation of this object.
	thicken	Creates a 3D solid object by thickening the surface by a specified amount.
	trimSurface	Trims a surface with 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.
	uIsolineDensity	Returns the number of isolines in the U direction of the surface, displayed in wireframe mode for visualization.
	vIsolineDensity	Returns the number of isolines in the V direction of the surface, displayed in wireframe mode for visualization.
