Build – Check Polygons – Polygons

Parameters for [Build-Check Polygons-Polygons] Dialog Box

Intersection

Checks for polygons intersecting with another polygon at points other than at shared vertices and

 

edges.

 

ex.) Polygons intersecting with each other

 

 

 

 

Degeneration

Checks for polygons whose edges intersect with each other at points other than at shared vertices.

 

ex.) Triangular polygon whose three vertices are positioned on a straight line

 

 

 

 

 

 

Vertex 1 Vertex 2 Vertex 3

 

 

 

 

 

Orientation

Checks for polygons that share an edge and face opposite each other.

 

 

 

ex.) Polygons sharing one edge and facing opposite each other

Connection

Checks for polygons that share more than three vertices or two non-edge vertices.

 

ex.) Quadrangular polygons sharing three vertices

 

 

Quadrangular polygon B

 

 

 

Quadrangular polygon A

 

 

 

 

 

 

 

 

 

 

ex.) Triangular polygon having as an edge the diagonal edge of a quadrangular polygon

 

 

 

 

 

 

 

 

Singularity

Checks for polygons connected to a vertex of conical polygons.

 

∗All the polygons connected to a vertex will be detected.

 

 

 

 

ex.) Triangular polygon sharing its vertex with a

 

 

conical polygon
