Description

This class represents Region entities in an OdDbDatabase instance.

An OdDbRegion entity is a wrapper for an ACIS model that represents the geometry of the OdDbRegion entity.

TD_Db

	Name	Description
	OdDbRegion	This is OdDbRegion, a member of class OdDbRegion.

OdDbRegion Methods

	Name	Description
	acisIn	Reads the ACIS data for this entity from the specified StreamBuf object.
	acisOut	Writes the ACIS data of this entity to the specified StreamBuf object.
	body	Returns the current modeler geometry.
	booleanOper	Performs a Boolean operation between this and another region object. Possible operation types are: kBoolUnite - unites two regions into one. kBoolIntersect - returns the intersection of two regions. kBoolSubtract - subtracts the region from the first one.
	brep	Returns the boundary representation of the 3D solid entity.
	createFromCurves	Creates OdDbRegion entities from the closed loops defined by the specified curve segments.
	decomposeForSave	Determines the behavior for custom objects when saving to .dwg or .dxf file.
	dwgInFields	Reads the .dwg file data of this object.
	DWGMAP_DECLARE_MEMBERS	This is DWGMAP_DECLARE_MEMBERS, a member of class OdDbRegion.
	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.
	getArea	Calculates the area of the region. Area value is returned in square drawing units.
	getAreaProp	Calculates the area properties of the region. The method validates the origin, xAxis, and yAxis parameters to ensure that: axes are perpendicular to each other. axes and the origin lie in the same plane as the region.
	getFaceMesh	This is getFaceMesh, a member of class OdDbRegion.
	getNormal	Returns the WCS normal to the plane of this entity (DXF 210).
	getPerimeter	Calculates the perimeter of the region. Perimeter value is returned in drawing units.
	getPlane	Gets the OdGePlane object that contains the region. If the region is Null, then the WCS X-Y plane is returned.
	internalSubentId	This is internalSubentId, a member of class OdDbRegion.
	internalSubentPtr	This is internalSubentPtr, a member of class OdDbRegion.
	isNull	Returns true if and only if there is no ACIS model associated with this entity.
	isPlanar	Returns true if the region is planar or false in the other case.
	numChanges	Returns the number of changes occurred since the region was created.
	saveAs	Creates a geometric representation of the region for saving proxy graphics or converting to previous formats.
	setBody	Directly sets the contained modeler geometry of this entity.
	subExplode	This is subExplode, a member of class OdDbRegion.
	subGetClassID	overridables
	subGetGeomExtents	This is subGetGeomExtents, a member of class OdDbRegion.
	subGetGsMarkersAtSubentPath	This is subGetGsMarkersAtSubentPath, a member of class OdDbRegion.
	subGetSubentPathsAtGsMarker	This is subGetSubentPathsAtGsMarker, a member of class OdDbRegion.
	subIntersectWith	This is the overview for the subIntersectWith method overload.
	subSetAttributes	Sets the values of this object's subentity traits, and returns with the calling object's subentity traits.
	subSubentPtr	This is subSubentPtr, a member of class OdDbRegion.
	subTransformBy	This is subTransformBy, a member of class OdDbRegion.
	subWorldDraw	This is subWorldDraw, a member of class OdDbRegion.
	TD_USING	This is TD_USING, a member of class OdDbRegion.
