Millwork drafting is the foundation of any successful woodworking or cabinetry project. Accurate shop drawings ensure smooth production, precise CNC machining, and error-free assembly. Unfortunately, drafting mistakes are a major cause of delays, material waste, and costly rework. Most of these errors, however, are preventable with standardized workflows, careful planning, and professional engineering support.
Incomplete or Missing Dimensions Why it happens:
- Rushed drafting
- No standard templates
- Designers assume the shop “already knows” sizes
Problems it creates:
- Misaligned cabinets
- Increased shop floor queries
- Installation errors
Solution:
- Include dimensions for plans, elevations, and sections
- Highlight critical points: overall sizes, clear openings, hardware locations
- Standardize dimension templates across all projects
Incorrect Material Specifications Why it happens:
- Outdated templates or libraries
- Confusion between imperial/metric measurements
Problems:
- Mismatched panels and edge banding
- Delays and material waste
Solution:
- Maintain a standardized material library
- Integrate materials into drafting software like Mozaik, Cabinet Vision, or Microvellum
- Include material schedules in drawings
Hardware Errors Why it happens:
- Using old hardware schedules
- Manual entries without verification
Problems:
- Wrong hinges, slides, or handles
- Slower installation and assembly issues
Solution:
- Keep an updated hardware library
- Use automated assignments in software
- Include hardware schedules and enlarged detail views
Inaccurate or Missing Section Views Why it happens:
- Reliance on 3D models only
- Rushing drawings
Problems:
- Shop guesses joinery
- Parts may not fit correctly
Solution:
- Include at least one section per unit
- Add detailed callouts for joinery, edge banding, and fasteners
- Standardize section symbols and labels
CNC Machining Mistakes
Why it happens:
- Wrong toolpaths
- Templates not synced with machines
Problems:
- Misaligned holes
- Wrong cut depths
- Material waste
Solution:
- Perform machining QC checks before export
- Maintain machine-specific templates (bit size, feed rates, drill bank config)
Poor Layer Management & Part Naming Problems:
- Confusion between drafters
- Miscommunication in cutlists and assembly
Solution:
- Standardize layers and color codes (cut lines, dimensions, hardware, construction)
- Use consistent part naming conventions
- Automate naming via Cabinet Vision, SolidWorks, or Microvellum
Ignoring Site Conditions Problems:
- Uneven floors
- Out-of-plumb walls
- Tight corners
Solution:
- Conduct site surveys
- Add tolerance allowances
- Include notes for adjustable fillers
Lack of QC Review Problems:
- Errors reach production
- Wasted time and material
Solution:
- Implement a two-step QC review
1. Drafter self-check
2. Lead engineer final check - Use checklist for dimensions, materials, hardware, sections, CNC outputs
