Public Class AreaMassProperties
	Implements IDisposable

The AreaMassProperties type exposes the following members.

	Name	Description
	Area	Gets the area solution.
	AreaError	Gets the uncertainty in the area calculation.
	Centroid	Gets the area centroid in the world coordinate system.
	CentroidCoordinatesMomentsOfInertia	Moments of inertia with respect to centroid coordinate system. X = integral of ((y-y0)^2 + (z-z0)^2) dm Y = integral of ((z-z0)^2 + (x-x0)^2) dm Z = integral of ((z-z0)^2 + (y-y0)^2) dm where (x0,y0,z0) = centroid.
	CentroidCoordinatesMomentsOfInertiaError	Uncertainty in centroid coordinates moments of inertia calculation.
	CentroidCoordinatesRadiiOfGyration	Radii of gyration with respect to centroid coordinate system. X = sqrt(integral of ((y-y0)^2 + (z-z0)^2) dm/M) Y = sqrt(integral of ((z-z0)^2 + (x-x0)^2) dm/M) Z = sqrt(integral of ((z-z0)^2 + (y-y0)^2) dm/M) where (x0,y0,z0) = centroid.
	CentroidCoordinatesSecondMoments	Second moments with respect to centroid coordinate system. X = integral of (x-x0)^2 dm Y = integral of (y-y0)^2 dm Z = integral of (z-z0)^2 dm where (x0,y0,z0) = centroid.
	CentroidCoordinatesSecondMomentsError	Uncertainty in centroid coordinates second moments calculation.
	CentroidError	Gets the uncertainty in the centroid calculation.
	WorldCoordinatesFirstMoments	Returns the world coordinate first moments if they were able to be calculated. X is integral of "x dm" over the area Y is integral of "y dm" over the area Z is integral of "z dm" over the area.
	WorldCoordinatesFirstMomentsError	Uncertainty in world coordinates first moments calculation.
	WorldCoordinatesMomentsOfInertia	The moments of inertia about the world coordinate axes. X = integral of (y^2 + z^2) dm Y = integral of (z^2 + x^2) dm Z = integral of (z^2 + y^2) dm.
	WorldCoordinatesMomentsOfInertiaError	Uncertainty in world coordinates moments of inertia calculation.
	WorldCoordinatesProductMoments	Returns the world coordinate product moments if they were able to be calculated. X is integral of "xy dm" over the area Y is integral of "yz dm" over the area Z is integral of "zx dm" over the area.
	WorldCoordinatesProductMomentsError	Uncertainty in world coordinates second moments calculation.
	WorldCoordinatesRadiiOfGyration	Radii of gyration with respect to world coordinate system. X = sqrt(integral of (y^2 + z^2) dm/M) Y = sqrt(integral of (z^2 + x^2) dm/M) Z = sqrt(integral of (z^2 + y^2) dm/M)
	WorldCoordinatesSecondMoments	Returns the world coordinate first moments if they were able to be calculated. X is integral of "xx dm" over the area Y is integral of "yy dm" over the area Z is integral of "zz dm" over the area.
	WorldCoordinatesSecondMomentsError	Uncertainty in world coordinates second moments calculation.

	Name	Description
	Compute(Brep)	Computes an AreaMassProperties for a brep.
	Compute(Curve)	Computes an AreaMassProperties for a closed planar curve.
	Compute(IEnumerable(GeometryBase))	Computes the Area properties for a collection of geometric objects. At present only Breps, Surfaces, Meshes and Planar Closed Curves are supported.
	Compute(Hatch)	Computes an AreaMassProperties for a hatch.
	Compute(Mesh)	Computes an AreaMassProperties for a mesh.
	Compute(Surface)	Computes an AreaMassProperties for a surface.
	Compute(Curve, Double)	Computes an AreaMassProperties for a closed planar curve.
	Dispose()	Actively reclaims unmanaged resources that this instance uses.
	Dispose(Boolean)	For derived class implementers. This method is called with argument true when class user calls Dispose(), while with argument false when the Garbage Collector invokes the finalizer, or Finalize() method. You must reclaim all used unmanaged resources in both cases, and can use this chance to call Dispose on disposable fields if the argument is true. Also, you must call the base virtual method within your overriding method.
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Finalize	Passively reclaims unmanaged resources when the class user did not explicitly call Dispose(). (Overrides Object.Finalize().)
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)
