How to Minimize Redlines in Custom Furniture Design

Updated: Aug 27, 2020

An important, time saving process of creating a technical drawing in the world of design and architecture is known as CAD, or Computer Aided Design technology. The creation of these precision drawings reduces the probability of human error, provide greater accuracy, and greatly shorten the design cycle.  


From a napkin sketch to final product, a custom-designed furniture piece passes through multiple variances, tweaks, and adjustments. Throughout this process, AutoCAD software allows hospitality designers to document changes and keep the entire team up-to-date. However, this important line of communication can be delayed with unclear CAD drawings, resulting in redlines. To minimize redlines in furniture design, it’s essential to exchange CAD drawings that clearly demonstrate the design intent.

With in-house CAD design, drawings, and 3D renderings with rotating model views, furniture manufacturers hold the custom manufacturing process to high standards. If any detail is in question, designers and engineers will  reach out to confirm the intended results. Rather than delay production with phone tag and out-of-office email responses, the typical redline issues and simple oversights that arise can be minimized when it comes to preparing CAD drawings for custom furniture design.



Deliver Clear and Updated Plans


The number one way to minimize redlines in furniture design is to deliver clear and up-to-date CAD plans and files. To assure plans are legible, remedy fuzzy plots by increasing dpi resolution when converting from DWG to PDF. Projects should be consistently updated, which also applies to any and all specifications such as a discontinued commercial-grade upholstery or modified casegood finish. As changes become executed, furniture designers need to know current specs and substitutions.



Be Consistent and Use Correct Labels

On the topic of updated plans and specifications, be diligent and correctly label all hardware, product numbers, and finishes.

Product numbers need to be specified and adequately labeled on plans. This applies to casegoods such as nightstands, desks, and built-in vanities, where specified product numbers as well as correctly label knobs, pulls, faucets, and any fastened or mounted hardware are essential.  Having hardware and lighting clearly marked makes packaging, scheduled deliveries, and furniture installation run more smoothly and on-time.


Furniture finishes and wood species need to be appropriately marked, including not only veneers and solid wood, but quartz and metals as well.  Be certain to specify the grain direction of  wood finishes and veneers.


In a competitive hotel market where ROI is crucial to success, specifications can drastically affect a hotel’s ROI. If not specified carefully for variables like climate and intended purpose, the finish can show wear and quickly appear outdated.



Specify wood species, finishes and hardware in notes

Be sure to label all cutout dimensions for wiring related to outlets or even sconce lighting installations in headboards or built-in vanities. These are very important to receive along with the spec package. Providing cut sheets help CAD engineers ensure that cutouts are correct and specifications are precise.  It is wise to send along samples of lighting fixtures, sinks, faucets, and fastened hardware for further assurance.



The Advantages of Graphics


Graphics can provide visual cues to designers and make navigation much more manageable when editing plans.  However, utilizing CAD standard layers and colors jointly must be properly executed.


While helpful to some degree, never solely rely on color codes when delivering plans. Color code layers often lose value when plotted in grayscale or photocopied, which is why ISO Standard line weights are the tried-and-true preferred method of computer-aided designs. The inverse is another common issue when printed drawings appear correct, but the CAD file itself is disorganized. Editing becomes a challenge with improperly set or unclear layers.


Cross-hatching is also a hand tool to distinguish multiple upholstery fabrics, wood species or casegood veneers.


Use a legend to distinguish between cross hatch patterns

Importantly, for these graphic layers and labels, details are wasted without coordinating Notes and Legends. Abbreviations, cross-hatching, and line weights must be itemized, leaving nothing to question, even annotations.
