Curved leads turned with the contour winding, which is backwards on outside perimeters: arc lead-ins arrived against the cut, and Line + Arc / arc lead-outs went the long way round on one winding. LeadTurn now gives the arc's turn direction for emission, the pierce-zone check and the preview, and the arc geometry mirrors with it. At convex outside corners, curved lead-ins use the first-cut edge's normal and arc lead-outs the last-cut edge's, whichever edge was picked. ArcLeadIn gains SweepAngle (degrees, (0, 180], default 180) in the cutting panel, settings, nest files and cut pins; older files read as 180. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Machine cutting defaults
A nest's assigned machine (Nest.Machine, see nest file format)
supplies the starting lead-ins, lead-outs, kerf and cut-off settings for the nest's
material and thickness, from that machine's Tools > Machine Configuration entry (in
Database mode, the server's shared machines once it holds them).
MachineCuttingDefaults (OpenNest.Data) holds the mapping; the desktop applies it.
Lookup
The machine's material must match the nest's material name, and its grade when the nest has one (otherwise the first grade on file). The thickness matches within 0.001 in after converting the nest's thickness to the machine's units, so a thickness rounded to three decimals (PEP stores 3/16 as 0.188) finds the machine's 0.1875; the nearest one wins. With no match, or no machine on file, nothing changes and the previous behavior applies. Lengths are converted from the machine's units to the nest's.
Lead-ins and lead-outs
A plate with no cutting parameters of its own (Plan Cutting, Place Lead-in) starts from the last applied parameters, as before, with the machine's leads and kerf laid over them and the machine, material, grade and thickness recorded on the parameters. A plate that already has parameters keeps them: changing the machine, material or thickness does not rewrite leads the plate was planned with.
The machine holds one lead-in and one lead-out per thickness; both go to external and internal contours (internal covers full circles). Types map as follows:
| Machine type | Lead-in |
|---|---|
| None | none |
| Line | line (length, angle) |
| Arc | arc (radius; the default 180-degree half-circle sweep) |
| Line + Arc | line-arc (length, radius, angle) |
| Clean Hole | clean hole (length, radius, the thickness's kerf), holes only: the external lead-in is kept |
| Line + Line | not mapped (the configuration has no second segment): every lead-in is kept |
Lead-outs map None, Line (length, angle) and Arc (radius); any other type is none.
Cut-offs
The plate view's part clearance, overtravel, minimum segment length and direction come from the machine's cut-off settings when a nest opens, when Nest > Machine changes the machine and after Nest > Edit saves. The head-locked overcut choice is kept. Existing cut-offs are not regenerated at that moment; they follow the settings the next time they regenerate.
