Defining a Layers Group Nesting

You can to optimize the number of parts that can be produced on a given material roll to reduce material waste.

  1. From the Review section of the action bar, click Layers Group Nesting .

    Layers Group Nesting is done in four steps:

    • Definition of the layers group shape, in the red frame below
    • Definition of the nesting base shape, in the blue frame below
    • Definition of the rectangular pattern
    • Computation of the net and gross weight for each material.

  2. Select the inputs.

    • The layers group
    • The delimitation domain. The boundary of this domain is used to define the delimitation of the base shape for the nesting.
    • The alignment constraint domain. This domain is aligned on the machine direction.

    In the example below, the Layer.1/Domain.1 is the delimitation domain. The Layer.2/Domain.1 is the alignment constraint domain.

    resulting in the following base shape

  3. Select the type of the shape from the list.
    • Single: Replicates the shape along the machine direction.
    • Horizontal invert: Places the first column along the cross direction, then duplicates it along the machine direction without rotation.
    • Vertical symmetry: Places the first column along the cross direction, then alternates duplications along the machine direction with 180 degrees rotations.
    • Invert vertical symmetry: Places the first row along the machine direction, then alternates duplications along the cross direction with 180 degrees rotations.
  4. Enter the number of pieces in the nesting.
  5. Click Preview.
    Gross, net, and Trim weights are computed and displayed.
