Part sub-program calls restored the sheet frame with G92 at the part corner while the tool sat at the sub-program's last endpoint, shifting every later part. The call now raises the head, rapids back to local 0,0 and restores there. Parts share a sub-program only when their posted toolpaths match, so per-part lead-ins are kept. Suppressed moves are left uncut: the cut resumes with a rapid past them. Head raises go before the rapid that leaves a feature, one per rapid: the safety raise now precedes the rapid to a new part instead of following its first feature, and sub-program mode no longer posts M47 then M47 P2000. M47Mode.Auto posts M47 before rapids longer than M47OverrideDistanceThreshold and /M47 otherwise. ExteriorM47 applies to the contour spanning the part's cut extents. The sheet GOTO targets FeatureLineNumberStart and is omitted without line numbers. PrepareForNest pre-selects only the gas- and thickness-matching library. Part programs are read through absolute copies, never switched to absolute in place. Removes the unimplemented UseSheetSubprograms, CoordModeBetweenParts and ProcessParameterMode (G89Mode); old configs still load. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
