Duplicate parts
At a glance
- Identical nested copies share one generated toolpath set—faster regeneration on large nests
- Each copy keeps its own position, rotation, and mirroring for preview, post, and simulation
- If leads no longer fit after placement, that copy regenerates independently
Production runs in Router are built from copies. Right-click a part for Duplicate (a single copy follows the cursor until you click to place it), Multiple Duplicate… (a quantity of each selected part, laid out in staging), Grid Array…, and Fill Sheet, which packs as many copies as fit around whatever is already on the sheet using the current nest effort. Quantities at import time — Set Each QTY… on the file import button, or the per-sketch quantity in the Drafting import dialog — create the same kind of copies.
One toolpath set per master
Every copy remembers which part it was cloned from. When you generate toolpaths, Router computes one toolpath set per group of identical parts on the active sheet, then hands each copy its own local copy of the result — so generation cost scales with the number of unique parts, not the number of copies. A nest of forty identical cabinet sides regenerates in roughly the time of one. Each copy still owns its position, rotation, and mirroring, which apply normally in preview, posting, and simulation.
When a copy goes its own way
Sharing only holds while the copies are truly interchangeable. Hidden, locked, and inactive-sheet copies are left untouched by group generation, and if a copy's placement means its lead-ins would run off the sheet, that copy is regenerated independently with leads that fit. Nothing to configure — the group optimization is automatic and falls back per-part only where it has to.
