Feature Edges (FeatureEdges)
This filter will extract edges along sharp edges of surfaces or boundaries of surfaces.
The Feature Edges filter extracts various subsets of edges from the input data set. This filter operates on polygonal data and produces polygonal output.

PropertyDescriptionDefault Value(s)Restrictions
Boundary Edges
(BoundaryEdges)
If the value of this property is set to 1, boundary edges will be extracted. Boundary edges are defined as lines cells or edges that are used by only one polygon. 1

Only the values 0 and 1 are accepted.

 
Coloring
(Coloring)
If the value of this property is set to 1, then the extracted edges are assigned a scalar value based on the type of the edge. 0

Only the values 0 and 1 are accepted.

 
Feature Angle
(FeatureAngle)
Ths value of this property is used to define a feature edge. If the surface normal between two adjacent triangles is at least as large as this Feature Angle, a feature edge exists. (See the FeatureEdges property.) 30

The value must be greater than or equal to 0 and less than or equal to 180.

 
Feature Edges
(FeatureEdges)
If the value of this property is set to 1, feature edges will be extracted. Feature edges are defined as edges that are used by two polygons whose dihedral angle is greater than the feature angle. (See the FeatureAngle property.) Toggle whether to extract feature edges. 1

Only the values 0 and 1 are accepted.

 
Input
(Input)
This property specifies the input to the Feature Edges filter.  

The selected object must be the result of the following: sources (includes readers), filters.

The selected dataset must be one of the following types (or a subclass of one of them): vtkPolyData.

 
Manifold Edges
(ManifoldEdges)
If the value of this property is set to 1, manifold edges will be extracted. Manifold edges are defined as edges that are used by exactly two polygons. 0

Only the values 0 and 1 are accepted.

 
Non-Manifold Edges
(NonManifoldEdges)
If the value of this property is set to 1, non-manifold ediges will be extracted. Non-manifold edges are defined as edges that are use by three or more polygons. 1

Only the values 0 and 1 are accepted.
