The Solid type exposes the following members.

Properties

	Name	Description
	Edges	The edges that belong to the solid.
	Faces	The faces that belong to the solid.
	GraphicsStyleId	The ElementId of the GeometryObject's GraphicsStyle (Inherited from GeometryObject)
	Id	A unique integer identifying the GeometryObject in its associated non view-specific GeometryElement. (Inherited from GeometryObject)
	IsElementGeometry	Indicates whether this geometry is obtained directly from an Element. (Inherited from GeometryObject)
	IsReadOnly	Identifies if the object is read-only or modifiable. (Inherited from APIObject)
	SurfaceArea	Returns the total surface area of this solid.
	Visibility	The visibility. (Inherited from GeometryObject)
	Volume	Returns the signed volume of this solid.

Methods

	Name	Description
	ComputeCentroid	Returns the Centroid of this solid.
	Dispose	Causes the object to release immediately any resources it may be utilizing. (Inherited from APIObject)
	Equals	Determines whether the specified Object is equal to the current Object. (Inherited from GeometryObject)
	GetBoundingBox	Retrieves a box that circumscribes the solid geometry.
	GetHashCode	Gets the integer value of the geometry object as hash code (Inherited from GeometryObject)
	GetType	Gets the Type of the current instance. (Inherited from Object)
	IntersectWithCurve	Calculates and returns the intersection between a curve and this solid.
	ToString	Returns a string that represents the current object. (Inherited from Object)

Remarks

A solid is defined by the faces and edges that form its boundary.
