Output ports
| Name | Type | Description |
|---|---|---|
| Sheets | Curve | Sheet boundary curves. Rectangular outlines for each sheet used. |
| Geometries | Geometry | Nested geometries transformed to their final positions on sheets. |
| Move Vectors | Vector | Translation vectors for each input geometry. Unplaced geometries have zero vectors. |
| Rotation Angles | Number | Rotation angles in radians for each input geometry. Unplaced geometries have zero rotation. |
| Sheet IDs | Number | Sheet index for each input geometry. Unplaced geometries have value -1. |
| Geo IDs | Number | Original input geometry indices for each nested geometry. |
