The OverlappingFaces Core Interface exposes methods for interacting with the Overlapping Faces xView Checker.

Available in 3ds Max 2010 and higher.

Properties:

    OverlappingFaces.tolerance : float : Read|Write

Get/set the tolerance value of the Overlapping Faces check. Corresponds to the value set in the Properties dialog of the test.

Methods:

    <enum>OverlappingFaces.Check <time>time <node>nodeToCheck <&index array>results

    Check enums: {#Failed|#Vertices|#Edges|#Faces}
    results is In and Out parameter

Performs an Overlapping Faces xView check at the given time on the specified node and returns its results in the array passed by-reference as third argument.

The method itself always returns the #faces enum because the values written to the results array always represent indices of overlapping faces.

    <bool>OverlappingFaces.hasPropertyDlg()

Returns true if the xView checker implements a property dialog, false if it does not.

In the particular case of the Overlapping Faces checker, it always returns true.

    <void>OverlappingFaces.showPropertyDlg()

Shows the Properties dialog.
