What Files to Send a Millwork Drafter: A Complete Input Checklist

There's a simple rule that holds across every millwork project I've managed: the quality of what you send determines the quality of what you get back. A drafter can only work with the information in front of them. When that information is incomplete, one of two things happens — they stop and ask questions before touching the drawings, which delays the start, or they make assumptions and proceed, which generates revisions once those assumptions surface. Either way, you lose time and money that a complete input package would have saved.

This checklist covers every category of input that affects the speed and accuracy of millwork shop drawing services. Use it before you send anything to your drafter. If you want the broader picture on how to structure the engagement itself, see our guide on how to brief a millwork drafter.

Architect or Design Intent Drawings

These are the foundation. The drafter needs to understand what the architect or designer intended before they can translate that intent into fabrication-ready shop drawings. DWG format is preferred — it lets the drafter import geometry directly without redrawing from scratch. A PDF is acceptable and often necessary as a backup, but native CAD files save hours on large projects.

At minimum, send:

• Floor plans showing millwork locations — marked with millwork tags or room references so the drafter knows what's in scope
• Interior elevations of all millwork walls — every elevation that shows a millwork unit, even if it looks simple
• Reflected ceiling plans if any millwork runs to the ceiling or is affected by ceiling conditions — soffits, bulkheads, and cove details all affect unit height and top treatment
• Any architectural details referencing millwork conditions, transitions to adjacent materials, or specific joint profiles

Even rough PDFs are better than nothing. If the design intent drawings are still in progress, send whatever exists and note the revision number clearly. The drafter will flag dimensions that need confirmation when the set is finalized.

Existing or Reference DWG Files

If you have previous projects drawn in a similar style or using the same construction standard, send one as a reference. This single step shortens the drafting setup time significantly — the drafter can match your layer naming conventions, line weights, text styles, and detail formatting without reverse-engineering them from scratch.

Also send:

• Your title block template — the drafter should be working in your block from day one, not creating a placeholder they'll swap out later
• Your standard detail library if you have one — typical section callouts, edge profiles, hardware blocking details, and installation notes that appear on every project
• Any shop-specific standards document — construction method preferences, material thickness standards, your specific approach to back panels, toe kicks, and shelf pin systems

Providing these reference files eliminates the most common category of clarification questions on a new engagement: "How do you normally show this?"

Hardware Specifications

Hardware decisions have a direct effect on the geometry of the drawing. Hinge model determines bore diameter and mounting plate dimensions. Drawer slide model determines the required side clearance and bottom clearance. Pull center-to-center affects door and drawer face layouts. These aren't details you can fill in after the fact without redrawing.

For each hardware category, provide the manufacturer and model number:

• Hinges — Blum, Salice, Grass, or other; full overlay, half overlay, or inset; with soft-close or standard
• Drawer slides — brand, model, extension type (full, over-travel), and weight rating
• Pulls and knobs — manufacturer, model number, and center-to-center dimension for pulls
• Locks, lid supports, and specialty hardware

If hardware selections haven't been confirmed yet, say so explicitly — don't leave it blank. The drafter will use standard placeholder hardware and note that field verification or a revision is required after selection. That's a clean workflow. What causes problems is when hardware is assumed to be "standard" without defining what standard means for your shop or this project.

Material and Finish Information

The drafter needs material information to write accurate callouts and to flag any conditions where material choices affect the construction method. Provide:

• Substrate: plywood (veneer core vs. MDF core, grade), MDF, or particleboard — and your actual thickness (3/4" nominal vs. 18mm matters)
• Face material: veneer species and cut, thermofoil product name, paint-grade MDF, or solid wood species
• AWI grade required: Economy, Custom, or Premium — this affects the level of detail required in the drawing package
• Finish color or code: paint color reference, stain formula, or laminate product name; if not specified, note "TBD" explicitly
• Edge treatment: solid wood banding species and thickness, PVC banding profile, or a specific profile detail

"TBD" on finish is actually useful information — it tells the drafter to leave finish callouts as notes flagged for later confirmation rather than inventing a spec. What wastes time is leaving finish fields completely blank, which requires a follow-up question to clarify whether the spec is genuinely open or just not yet transmitted.

Field Measurements

For renovation work, tenant fit-outs, or any project where millwork is going into an existing space, field measurements take priority over the architect's drawings. Buildings are never exactly as drawn. Ceiling heights vary by several inches between one end of a room and the other. Walls are not always plumb. Existing fixed elements — columns, ducts, sprinkler heads, electrical panels — sit where they sit, not where the drawings show them.

Send field measurements as:

• A hand sketch with dimensions — it doesn't need to be to scale, it needs to be readable
• A marked-up PDF of the floor plan or elevation with actual field dimensions written in
• A dimensioned photo set if the conditions are complex — photos of corners, returns, and ceiling junctions are especially useful

Note ceiling height at multiple points, not just one. Note any wall irregularities. Note existing elements that the millwork has to clear or coordinate with. If field measurements aren't available yet, flag it — the drafter will dimension from the architectural drawings and note that all dimensions require field verification before the shop cuts.

Project-Specific Notes

Every project has conditions that don't show up in the drawings but affect how the millwork gets designed and built. These need to be communicated in writing, not left for the drafter to discover mid-production:

• Installation sequence requirements — if certain units must be installed before others due to access or phasing, the drafter needs to know; it affects how assemblies are broken up
• Special environment conditions — high humidity areas (locker rooms, kitchens, labs) affect substrate and finish choices; the drafter needs to flag these if the spec doesn't
• ADA compliance requirements — counter heights, knee clearance dimensions, reach ranges; if ADA applies, note which elements are subject to it
• Fire rating requirements — if millwork must meet a specific fire rating, this affects material selection and may require specific callouts
• Trade coordination requirements — electrical outlets or data ports inside millwork, under-sink plumbing, integrated lighting, or HVAC grilles in millwork panels all need to be called out so the drafter can show blocking, cut-outs, and clearances

The more the drafter knows about these conditions upfront, the fewer "did you know about this?" emails you receive mid-project. See the shop drawing checklist for a broader review of what a complete package looks like at submittal.

Your Output Requirements

The drafter needs to know what you expect to receive, not just what to draw. Specify:

• File formats: DWG version (AutoCAD 2018, 2020, 2024), PDF, or RVT — if the GC or architect has specific version requirements, pass those along
• Sheet size: 24×36, 30×42, or 11×17 for smaller packages
• Scale preferences: most millwork shops want plans at 1/2"=1'-0" and details at 1"=1'-0" or 1-1/2"=1'-0", but confirm your preference
• Title block: your own title block, the GC's title block, or a standard block — provide the template file, not just the logo
• Revision format: how revisions are tracked on the sheet — revision clouds, delta triangles, revision table format
• Submittal format: whether the package needs a cover sheet, sheet index, and transmittal, or just the drawing sheets

Output requirements are easy to specify and easy to forget. Getting the wrong file format or sheet size delivered at the end of a project is a frustrating, avoidable problem.

What Happens When Inputs Are Incomplete

Incomplete inputs don't just slow the project down — they create compounding problems. Here's a concrete example: the hardware spec isn't confirmed before drawing starts, so the drafter uses a Blum 110° clip-top hinge as a placeholder. The owner selects a Grass Tiomos 110° hinge after the first draft is issued. Those two hinges have different mounting plate dimensions and different boring patterns. Every door and drawer front in the set needs to be checked and potentially revised. That's not a note change — it's geometry work across every sheet that shows a door or drawer.

The same pattern applies to field measurements. If the architect's drawing shows 9'-0" ceiling height and the field is 8'-9" at one end of the room, the tall cabinet unit drawn at 96" hits the ceiling at the low end. The revision isn't just changing a number — it's figuring out how to handle the transition, whether a scribe is appropriate, whether the unit needs to be split, and whether the elevation still reads as designed.

Every assumption a drafter makes without confirmed information is a potential revision. Assumptions aren't failures of drafting skill — they're the predictable result of incomplete inputs. Check our millwork drawing rates to understand how revision rounds affect project cost.

Better Inputs, Faster Turnaround

The checklist above isn't exhaustive for every project type, but it covers the categories that generate the most clarification questions and revision cycles in practice. Send everything you have in each category, note explicitly what's still TBD, and flag any unusual project conditions upfront. That package gets you a first draft you can actually review — not a set of assumptions that need to be unwound.
