Multi Chair Placement

Multi Chair Placement enhances the placement of chairs so they can automatically be placed around a table. When placing a chair from the toolbox, hover the chair above a Worksurface and it will show the placement of the chosen chair around the whole table.

Worksurface Methods

In Worksurface in Abstract Office, there are 3 methods are relevant to this functionality:

    /**
     * Allow multi chair placement.
     */
    extend public bool allowMultiChairPlacement() {
        return false;
    }

    /**
     * Mulit chair spacing.
     */
    extend public double multiChairSpacing(Snapper chair) {
        return 29.5inch;
    }

    /**
     * Chair placer.
     */
    extend public ChairPlacer chairPlacer(Snapper chair) { }

Chair

The Chair class may need to implement the following methods:

    /**
     * Multi chair insert position.
     */
    extend public point multiChairInsertPoint() {
        return tableSnap ? tableSnap.pos : (0, 0, 0);
    }

    
    /**
     * Multi chair insert rotation.
     */
    extend public angle multiChairInsertRot() {
        return tableSnap ? tableSnap.rot.yaw : 0deg;
    }

The ChairPlacer Class

The ChairPlacer class instantiates a temporary (unstreamable) object that are used during the InsertAnimation of a Chair. The ChairPlacer class should be filled in with information about how to place chairs around a specific worksurface/table using the method in Worksurface (or overriden to handle other types of Snappers).

It contains 1 or more SnapperPlacerItem that are created in chairPlacer() in Worksurface (or overriden to handle other types of Snappers) and describes how a specific chair should be placed.

These two classes resides in cm/abstract/office/chairPlacer.cm

Customization Needs

If your Tables/Worksurfaces are inheriting from the abstract office class Worksurface, the base coding that needs to be done on the Table is:

    /**
     * Allow multi chair placement.
     */
    public bool allowMultiChairPlacement() {
        return true;
    }

If not, similar code to that found in Worksurface must be implemented in the base class.

If the chair 0-point and/or rotations does not match the standard in abstract office, the multiChairInsertPos() and multiChairInsertRot() should be implemented from the Chair.
