Nestor Settings
The nestor controls how WSi arranges parts on a sheet or tube during nesting — the search for the placement that uses the least material. This affects Laser Sheet Cutting, Plasma Sheet Cutting, Waterjet Sheet Cutting, and Tube Cutting.
These settings live in two places: the defaults for all workstations are in the database's Advanced Settings, and you can also override the nesting mode for your workstation.
Nesting mode for your workstation
Open Settings → Client → Miscellaneous settings.
| Setting | What it does |
|---|---|
| Sheet nesting mode | Nesting mode for sheet metal parts on this workstation |
| Tube nesting mode | Nesting mode for tube parts on this workstation |
With Application default, the Nesting mode from the database's Advanced Settings applies.
Nesting Modes
| Mode | Description |
|---|---|
| Actual quantity (mixed) | Compatible nodes are nested together on the same sheet, each with its actual quantity. |
| Actual quantity (individual) | Each node is nested on its own with its actual quantity. |
| Virtual quantity (individual) | Each node is nested on its own; consumption is derived from nesting a single sheet, regardless of the actual quantity. |
The Advanced Settings describe when each mode fits.
Defaults in the database
Open Settings → Database and select Advanced settings. The nestor values are on the Sheet cutting and Tube cutting tabs:
| Setting | Tab | What it does |
|---|---|---|
| Nesting mode | Sheet cutting, Tube cutting | Default nesting mode |
| Nesting distance | Sheet cutting, Tube cutting | Distance between adjacent parts |
| Sheet scrap minimum contour area | Sheet cutting | Lower threshold for an area to count as scrap rather than trash |
| Clamping length | Tube cutting | Length reserved for clamping, unavailable for nesting |
TIP
A smaller nesting distance reduces waste but increases the risk of parts being too close together for cutting. Check your cutting machine's minimum clearance requirements before setting a tight distance.
