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

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.

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.
