Panel assembly
Overview
Links in PolyBoard describe the join between 2 panels that are neighbours to each other. Links apply to the outer panels of a cabinet, and also to shelves, uprights, doors and drawers.
As well as describing the relationship between panels and design elements, you can also link to the front of the cabinet.
These links can be modified to create a huge range of custom assemblies.
They can be configured one at a time or most effectively by adding them to Quick Design manufacturing methods for click of a button application to all your design projects.
Link priority
(overpassing, underpassing and mitre joints)
The link priority setting is one of the parameters that allow us to edit the nature of the link or the join between 2 panels.
The 3 options are overpassing, underpassing and a mitre joint.
Overlapping joint
(overpassing panels only)
If you set the link priority of a panel to overpassing, you have the option to add an overlap, which extends it beyond the panel it is assembled to.
You can also apply a negative overlap to reduce its length.
Recess joint
(underpassing panels only)
In this video we’ll create a recess joint, which allows us to add a gap between two panels.
It’s not possible to set the link between a panel and the front of a cabinet to underpassing, which is required for a recess joint.
Instead, we show you how to move a panel forward and backwards in relation to the cabinet frontage by using the overlap feature.
Groove joint / rebate joint
(underpassing panels only)
In this video we’ll show you how to create a groove joint. The first step in the process is to create a rebate joint so that’s covered here too.
Mortise and tenon joint / tongue and groove joint
(underpassing panels only)
The mortise and tenon feature is really a feature for creating tongue and groove joints, with a shoulder to hide it if required. It also allows you to create a dado and rebate joint and a double rebate joint as you’ll see in this video.
Update: an asymmetrical shoulder is now possible, see the image below:

Halving joint
How to add a halving joint assembly to your cabinets.
For extra flexibility the second panel you add to complete this assembly is defined as a free division which allows it to be positioned at an angle.
Bevels
Particularly if you are designing with angled components, having tight control over the groove of one panel into another is important.
The bevel parameter options allow you to fine tune the configuration, the 1 bevel option is highlighted below, the view is from above.

This compares with the Default bevel option below:

Typically the bevel feature may also be used to adjust a door panel in an angled cabinet for a simpler cut, rather than its edge following the line of the side panel.
Below we’ve applied the option: Angle (face 2) at 90°:

The full range of options are:
- Default: follows the angle of the cabinet
- Straight edge (-): straightens the edge based on the shorter side of the bevel
- Straight edge (+): straightens the edge based on the longer side
- 1 or 2 bevels: 1 or 2 bevels into a groove perpendicular to the face of the grooved panel
- Angle (face 1 or 2): manual input of angle referencing face 1 or 2
The Cabinet boxful manufacturing sub-method also includes this parameter for quick application and modification across multiple cabinets and projects.
Chamfers
Angled cuts (chamfers) can also be applied to the panel edge. Below is an example of chamfers added to the inside and outside faces.

Bevels and chamfers can also be used in combination with each other.
