Description

Example of the boxToFace topoSet by using actions sub-dictionary in system/topoSetDict file:

{
    // Mandatory (inherited) entries
    name        <name>;
    type        faceSet;
    action      <action>;

    // Mandatory entries
    source      boxToFace;

    // Conditional mandatory entries
    // Select either of the below

    // Option-1
    boxes
    (
        (<minX> <minY> <minZ>) (<maxX> <maxY> <maxZ>) // box-1
        (<minX> <minY> <minZ>) (<maxX> <maxY> <maxZ>) // box-2
        ...
    );

    // Option-2 
    box (<minX> <minY> <minZ>) (<maxX> <maxY> <maxZ>);

    // Option-3
    min (<minX> <minY> <minZ>);
    max (<maxX> <maxY> <maxZ>);
}

where the entries mean:

Property	Description	Type	Required	Default
name	Name of faceSet	word	yes	-
type	Type name: faceSet	word	yes	-
action	Action applied on faces - see below	word	yes	-
source	Source name: boxToFace	word	yes	-

Options for the action entry:

new      | Create a new faceSet from selected faces
add      | Add selected faces into this faceSet
subtract | Remove selected faces from this faceSet

Options for the conditional mandatory entries:

Entry    | Description                    | Type       | Required    | Default
boxes    | Multiple bounding boxes        | vectorList | conditional | -
box      | A single bounding box          | vector     | conditional | -
min      | Minimum point for a single box | vector     | conditional | -
max      | Maximum point for a single box | vector     | conditional | -

Notes on entries

The order of precedence among the conditional mandatory entries from the highest to the lowest is boxes, box or a min-max pair (compatibility with searchableBox).
