Margins and spacing in nesting
These are separate layout constraints and should reflect the process, material and machine.
Sheet margin
A margin reserves an area near a sheet edge. It may account for fixturing, edge quality or process requirements. Set the value for the specific application.
Part spacing
Spacing prevents neighboring contours from being placed too close together. Adequacy depends on technology, kerf and production rules. Geometric distance alone does not validate a toolpath.
Validate the result
Check contours against the sheet and each other, then consider cut order and part stability. Do not copy a value without confirming it for the process.
