3 top ways casework shop drawings impact cabinet quality
Designing the right-fit cabinets, manufacturing, and installing them perfectly can be overwhelming due to the involvement of multiple stakeholders. Cabinet shop drawings resolve issues by displaying information and 360-degree design intent in a single file.
Without cabinet shop drawings displaying clear design intent, manufacturing details, and Bill of Materials (BOM) it is difficult to produce high-quality casework. Because cabinet shop drawings contain information on design aspects, exact geometry with tolerances, material type, and machine allowances that workers on the shop floor need to know.
Cabinet drafting standards like AWI and ANSI ensure the drawings are safe, accurate, and purposeful. They provide guidelines to ensure the cabinet base can hold the weight of the structure and store merchandise with no damage.
Going beyond their primary utility, casework shop drawings resolve differences of perception between manufacturers, contractors, and designers. Thus, the level of information they carry determines the final quality of the installed casework.
Challenges in manufacturing built-in cabinets
Manufacturing a quality cabinet can become overwhelming when there are too many design suggestions and iterative design changes. But these are challenges that cabinetmakers have to face. Any casework manufacturing workflow has to tackle issues with:
Multiple design revisions
Several levels of design approvals
Working with hybrid primary materials
Managing all information without cluttering the drawing sheet
Reducing scrap
By providing a single source of truth, cabinet shop drawings enhance design communication across teams.
They encourage innovation during design development, and also efficient design handoffs, by promoting collaborative inputs.
Three ways cabinet shop drawings influence casework quality
Casework shop drawings provide detailed design and manufacturing blueprints for cabinet manufacturers. They are critical for:
1. Eliminating dead spaces
The space under a staircase is a great example of a dead space often converted to a storage area with casework. But it requires bespoke cabinets and extra challenges in manufacture and installation. Shop drawings help to overcome these challenges and build casework that blends into its settings.
With detailed shop drawings, one can get:
Perfect component information: 2D cabinet shop drawings carry information regarding manufacturing operations for cutting the wood, metal, or glass to fit casework dimensions. They illustrate clearances between components, between material and construction work, and the allowances for fixing nuts and screws.
Insights for accurate measurement: For the correct installation of cabinets into spaces without leaving behind any unused cavities, the design and manufacture of the casework need to be highly accurate. All irregularities can be tackled with the geometry specified in cabinet shop drawings as they reference raised architectural floor plans.
Room for accommodating drawing changes: Spaces between masonry and furniture not only affect aesthetics but also furniture durability. Cabinet drawings developed from raised floor plans consider all the latest changes in the existing structure, the height of tiles to be fixed on the floor, etc. Casework drawings also have room to accommodate changes based on the updates from contractors and architects on site.
In a project of installing glass cabinets to showcase exhibits in a museum, Hitech CADD Services teams developed detailed shop drawings based on the raised architectural floor plans. This removed any possibility of errors between the sizes of furniture and the actual space allocated for their construction.
2. Ensuring hassle-free assembly and installation
Shop drawings are developed considering the type of material of the cabinet, door closure type, etc. For example, in residential settings, floating cabinets and shelves on walls are often surrounded by TV units or other electronic equipment. They need special attention from designers to ensure proper mounting on walls, and to safely carry the loads they are built for.
Meticulous planning of dimensions with standard methods and 2D CAD drafting is used for good cabinet drawings. A complete set of detailed casework drawings have:
Detailed cabinet shop drawings with assemblies
Onsite installation guides
ISO model
These accompaniments ensure that the site manufacturing, assembly, and installation conform to the standards. All the screws, joineries, parts, etc. are assembled as intended for safety.
To ensure zero damage to wooden parts and metal frames in changing of room furniture for a retail store furniture manufacturer, Hitech CADD Services’ engineers created an installation guide along with assembly sequencing animation. The sequential video and detailing drawings contained information related to transport precautions, unpacking of boxes, arranging the fixtures, etc.
3. Effective use of corners across buildings
Buildings have corners and uneven spaces. Designing and manufacturing cabinets for such areas could be difficult. But with cabinet shop drawings, architects and furniture design engineers can agree during design development. A set of cabinet drawings with cross-section, elevation, and plan views comprehensively shows details about the furniture piece and how it fits into the building or around a corner.
For example, an isometric drawing shows a 3D object and its relationship with other parts. Usually, casework drafting employs a grid at 30 degrees from the horizontal axis to explain construction details. Thus, it communicates both the precision of design and the appearance of the furniture.
Final thoughts
Cabinet shop drawings also help in planning and finalizing interiors, as interior designers can give the end customer a clear idea of geometry, material, sizes, and other attributes of casework alternatives, and make informed decisions.
The more detailed the shop drawings, the smoother the manufacturing and the fewer change orders. And by providing a robust channel for communication between shop floor engineers and design teams, casework shop drawings define the quality of finished products. It makes them indispensable in cabinet manufacturing.
