How to split shapes for a better nesting?

If your input file does not group shapes in an optimal way, you can split each shape into individual files and then re-nest them to improve layout efficiency in PrimeCenter. Having one file per shape is especially useful for applications like lettering.

How it works

Splitting and re-nesting shapes involves two steps:

  1. Apply the “Split for re-nest” check/fix profile.

  2. Nest the newly generated files. For more details on nesting, see Nesting in PrimeCenter.

 

Prerequisites

Before applying the profile, you may need to learn more about check/fix profiles:

 

Configuring the “Split for re-nest” profile

This profile includes several settings to define how shapes are split.

PrimeCenter V3.1

 

Contour

📌 Contour selection

This option is available since PrimeCenter V3.1.

Select which contours to use for splitting:

  • Specific contours: Choose specific cut contour names from the Cut contours list (formerly "Dictionary").
  • All detected contours: Automatically considers all contours in the Cut contours list (formerly "Dictionary").

      Warning

    If multiple contours are detected in the file, all of them will be used for splitting.

 

📌 Remove objects after split

Choose how objects outside the split shapes are handled:

  • Outside of the page area (optimized): Removes objects outside the page area. Objects inside the page area are kept, and those crossing the edge are hidden.
  • Outside of the shape area (slower): Removes objects outside the shape’s contour. The output PDF will contain only the split shapes.
  • None: All objects are kept but hidden.

📌 Create shape on most external contour

  • ✅ Enabled: Only considers the most external contour.
  • ❌ Disabled: Generates a file for each cut contour inside the shape.

Adjustments

  • Minimal object size: Define the minimum size of shapes to be considered for splitting.
    • Example: If set to 5 mm, smaller shapes will be ignored.

  • Tolerance for detection: Set a tolerance value for detecting contours. If set to X mm, contours larger than X mm may not be detected correctly.

 

Examples

Example 1: Lettering for signs

Split for re-nest settings

  • Contour: CutContour (name used in the input file)
  • Minimal object size: 0 mm
  • Remove objects after split: Outside of the shape area
  • Create shape on most external contour: ✅ Enabled

 

Result

16 files generated (one per shape).

Split for re-nest settings

  • Contour: cutcontour (name used in the input file)
  • Minimal objects size: 5 mm
  • Remove objects after split: Outside of the shape area
  • Create shape on most external contour: ✅ Enabled

 

Result

27 files generated (one per shape).
