Add hardware to custom panels with rules and connectors

Cover custom panels with hardware rules, or add connectors manually where rules do not reach.

1. Connectors at carcass-to-carcass junctions between custom panels therefore have to be added manually, keeping the source as manual and selecting the required hardware.

2. A rule can be copied onto the drawer carcass panels to apply it there.

3. Hardware rules are set on scenarios between panels: a condition can target the panel type of Panel 1 or Panel 2 (shelf, vertical partition panel, shutter panel, carcass panel and the other panel types) and the scenario type (Eccentrics, Hinge, Cabinet Connector, Single Panel Connector). Carcass panels are covered as well: a rule whose two panels are 'Carcass Panel' with the scenario type Eccentrics adds hardware to the carcass joints, for example a minifix and a wooden dowel.

4. Connectors added automatically by hardware rules can include minifix dowels, for example at carcass-to-carcass and carcass-to-rail joints.

5. A scenario that involves only a single panel — for example a bottom panel that receives cabinet legs — does not need a connector, since there is no second panel to join; the Single Panel Connector scenario type is designed for exactly this case.
