Check: Duplicate

Function

Check Duplicates allows users to confirm contact between two surfaces.  Duplicated faces are represented as yellow.  

Call

Geometry > Check > Check Duplicates   

<Check Duplicate dialog box>

Visible Shapes Only

Check Duplicates of Shapes, which exist on the screen.  Checks can be carried out on shapes irrespective of Show/Hide.

Tolerance

Specify Tolerance range.

Check Duplicate Vertices

Duplicate Vertices, which exist independently, are checked.  Duplicates are displayed as red circles.

Include Sub-Vertices

Duplicate Checks are carried out on vertices, which exist as sub-shapes (eg., corners of a box) as well.

Check Duplicate Edge/Wire

Duplicate Edges and Wires, which exist independently, are checked.  Duplicates are displayed as red lines.

Include Sub-Edge

Duplicate Checks are carried out on edges, which exist as sub-shapes (eg., edges of a quadrilateral) as well.

Check Duplicate Faces

Duplicate Faces, which exist independently, are checked.  Duplicates are displayed as yellow surfaces surrounded by red lines.

Include Sub-Faces

Duplicate Checks are carried out on faces, which exist as sub-shapes (eg., a face of a hexahedron) as well.
Exact Boundary Topology

This option checks duplicates of perfectly identical faces.  Identical faces mean those faces, which coincide in the number of vertices and their coordinates, and the directions of the edges, which exist at the boundaries of the faces.

Remove Duplicated Shapes

It finds and removes duplicated independent Shapes (sub-Shapes will not be deleted).

Notes

If a face is partially duplicated, it is not checked for duplication unless it has a boundary box.

The use of the Exact Boundary Topology option speeds up a duplicate check process.  But the number of checks, which can be performed, becomes limited.
