Geometry (Surfaces)

Builds nesting parts from planar surfaces instead of curves; holes are read from the surface boundaries.

Inputs

Parameter	Type	Access	Description
Surfaces	Brep	list	Planar boundary surfaces. If you want to nest multiple sheets partition surfaces into the data-tree.
Simplify	Number	item	segment divisions 0 takes only ends x>0 divides by distance x<0 max 3 points per sub-segment) Default: -100.
Hull	Boolean	item	Use the convex hull of each simplified outline. Default: false.
Copies	Integer	list	Number of copies per part.
Offset	Number	item	Clearance offset for NESTING only (model units; 0 = OFF, fast). Parts: outer grows / holes shrink so placed parts keep this gap. The ORIGINAL curves are still what get placed/output. Default: 0.
Rotations	Integer	list	OPTIONAL per-part rotation constraint (one value per part, repeats like Copies). Empty / 0 = part inherits the solver's global Rotations setting (default). N > 0 = THIS part may only use N orientations (360/N degree steps). 1 = fixed, no rotation (e.g. grain direction). Lets rectangular parts stay at 4 orientations while freeform parts rotate freely in ONE nest.
Attributes	Geometry	list	Additional geometry: points, lines, surfaces, meshes... Use data-tree, one list of additional geometry per branch..

Outputs

Parameter	Type	Description
Geometry	Generic	Nesting parts ready for the solver.
Borders	Curve	Outline curves of each part.
