DXF Layer Mapping Checklist for Fabrication Shops

An actionable process to map customer DXF layers to your shop’s cut, mark, drill, and bend-reference conventions before CAM — for laser, plasma, waterjet, and sheet-metal teams.

Why a written map beats tribal knowledge

If only one programmer “knows” that CUTTING becomes CUT and DIM gets deleted, every vacation and new hire restarts the same discovery. A DXF layer mapping checklist turns that into a shared shop document: customer names in, shop names out, with an explicit action per row.

The four columns

Use this table structure (also in the free worksheet):

CUSTOMER LAYER	SHOP LAYER	ACTION	NOTES
`LASER`	`CUT`	REMAP	Alias for outer/inner cut
`CUTTING`	`CUT`	REMAP	Same destination as LASER
`CUT`	`CUT`	KEEP	Already shop-standard
`ETCH` / `ENGRAVE`	`ETCH`	REMAP or KEEP	Confirm mark vs cut intent
`BEND`	`BEND`	KEEP	Reference only — not a cut path
`DIM`	—	DROP	Dimensions / annotation
`CONSTRUCTION`	—	DROP	Guides / centerlines

KEEP, REMAP, DROP explained

KEEP — customer name already matches your CAM / nest profile; leave it (optionally normalize color).
REMAP — rename the layer (and usually color) to the shop standard so import rules fire correctly.
DROP — remove geometry that should not enter the production DXF (dims, title-block leftovers, construction).

Anything not listed is unmatched. Decide shop policy: stop the run, park the file, or assign a temporary “REVIEW” layer — but do not silently invent a mapping under pressure.

Step-by-step mapping process

List every unique layer name from a representative set of customer DXFs (last month’s jobs is enough).
Write your target shop layer list (cut, inner cut if used, mark/etch, bend, drill, ignore).
Fill CUSTOMER LAYER / SHOP LAYER / ACTION / NOTES for each row.
Review with programming and estimating so aliases are agreed once.
Publish a customer-facing subset in intake docs; keep the full alias list internal.
Apply the map consistently — manually at first, then with a saved profile when volume justifies it.
After CAM import, spot-check that tools match intended layers; adjust NOTES when edge cases appear.

Apply the map in batch

When the same rows appear on every job, Shop DXF Standardizer stores your profile and batch-processes a folder of customer DXFs on Windows — remap, keep, or drop layers and colors, preview first, then write shop-standard copies plus a report. $99 one-time. It does not repair geometry or guarantee CAM acceptance.
