ExtrusionAnalyzer Class


Extrusion Analyzer Class

This geometry utility allows you to attempt to "fit" a given piece of geometry into the shape of an extrusion.

Syntax
public class ExtrusionAnalyzer : IDisposable

The ExtrusionAnalyzer type exposes the following members.

Properties
Name Description
Public property EndParameter The end parameter (distance along the extrusion direction from the input plane) calculated by the extrusion analysis.
Public property ExtrusionDirection The direction of extrusion specified for the extrusion analysis.
Public property IsValidObject Specifies whether the .NET object represents a valid Revit entity.
Public property StartParameter The start parameter (distance along the extrusion direction from the input plane) calculated by the extrusion analysis.

Methods
Name Description
Public method CalculateFaceAlignment Calculates the alignment status of each face of the solid.
Public method Static member Create Creates an ExtrusionAnalyzer and computes and stores the solid's shadow.
Public method Dispose Releases all resources used by the ExtrusionAnalyzer
Public method Equals Determines whether the specified object is equal to the current object.
(Inherited from Object )
Public method GetExtrusionBase Obtains the face that represents the base contour of the extrusion analysis.
Public method GetHashCode Serves as the default hash function.
(Inherited from Object )
Public method GetType Gets the Type of the current instance.
(Inherited from Object )
Public method ToString Returns a string that represents the current object.

Remarks

An instance of this class is a single-time use class which should be supplied a solid geometry, a plane, and a direction. The utility will calculate a base boundary parallel to the input plane which is the outer boundary of the shadow cast by the solid onto the input plane and along the extrusion direction.

After the extrusion has been calculated, the class permits a second step analysis to identify all faces from the original geometry which do not align with the faces of the calculated extrusion.

This utility works best for geometry which are at least somewhat "extrusion-like", for example, the geometry of a wall which may or may not be affected by end joins, floor joins, roof joins, openings cut by windows and doors, or other modifications.

The ExtrusionAnalyzer expects only one single extrusion-like solid geometry. The ExtrusionAnalyzer does not support a Geometry containing multiple solids.
