Name  Description  

Compute(Brep) 
Computes an AreaMassProperties for a brep.
 
Compute(Curve) 
Computes an AreaMassProperties for a closed planar curve.
 
Compute(IEnumerableGeometryBase) 
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 ObjectFinalize.)  
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.)
