Optimising parameter to set the minimum size and area for an offcut
These values define the minimum size for an offcut. The program uses this definition wherever offcuts are used. Set this value to reflect the size of material that is the smallest useful piece (offcut).
● Enter values for the minimum length and width
● Enter a value for the minimum area
Offcuts are shown on the pattern drawing by a different colour or a wide hash pattern (see Review runs - Settings)
A piece of waste is defined as an offcut by the following rules.
- Longest side exceeds minimum length
- Shortest side exceeds minimum width
- Area exceeds minimum area
For metric area use square metres, for Imperial area (feet and inches) square feet.
Use of offcuts - If offcuts are available in the board list the optimisers attempt to use these in preference to stock boards, unless the cost of using offcuts is too high. The general rule used is that the cost per area of the pattern using the offcut must be less than the cost per area of the cost of an alternative pattern using the stock board. As a rule of thumb if the cost per area of the pattern using the offcut is less than the cost per area of the board material (regardless of the actual cutting pattern it contains) the offcut is preferred.

Notes
- Can also be set as a material parameter at both board and material level
- The default settings for these parameters are (millimetres) : 9999,9999,0. This ensures that if the parameter are not set no offcuts are produced.
