Extract Edges

This effect can extract edges from mesh based on their properties.

Input

polygonal mesh

Output

edge wireframe

VTK classes

vtkFeatureEdges, vtkTriangleFilter, vtkCleanPolydata

Options

../_images/properties-extract-edges.png
Extract feature edges

Whether “sharp” edges should be extracted.

Tip

This refers to angle between faces, not explicitly marking edges as Sharp in Blender.

Feature edge angle

Minimum angle between faces to consider an edge as a “feature” edge.

Extract boundary edges

Whether boundary (ie. having just one face) edges should be extracted.

Extract non-manifold edges

Whether non-manifold (ie. having three or more faces) edges should be extracted.

Extract manifold edges

Whether manifold (ie. having two faces) edges should be extracted.
