They are defined as follows:

  • Net dimensions = panel dimensions without edging and including oversizing
  • Overall dimensions = includes panel dimensions and edging thickness

Net dimensions are displayed in round brackets and overall in square brackets.

Here net dimensions are shown in the cutting list:

When only one bracket is shown, this indicates the edging position.


Net or overall dimensions (or even both) can also be displayed on the labels:

When working in net dimensions, edging thickness will be deducted from the panel dimensions.
You can modify exactly how the deduction is calculated in Tools > Preferences > Panels > Thickness compensation settings:

edge banding preferences

The options available are:

  • No compensation: deducts the actual edge thickness
  • Maximum: adds a maximum compensation value without exceeding the actual edge thickness
  • Fixed: adds a fixed value for each edge which can also exceed the edge thickness
