Why Furniture Drawings are Essential for Quality Furniture Manufacturing
Furniture manufacturers deal with the raw materials, processing, and assembly of different parts that make up the furniture. The challenges faced by furniture manufacturers directly impact the finished product in terms of quality, turnaround time, and feasibility.
Let us Explore Some of the Common Challenges Faced by Furniture Manufacturers
Changing industry trends
Furniture industry trends change rapidly, and furniture manufacturers are expected to catch up with these fast-changing trends. As a result, the furniture market is extensive, with new designs being imagined and executed daily.
Lengthy-time from design to production
The iterative design process elongates design cycles from concept to manufacturing and is also erroneous due to multilevel approvals. It diminishes manufacturing efficiencies and increases the chances of material wastage and loss of time.
Customization capabilities
Customization remains a key differentiator for furniture manufacturers to thrive in a competitive environment. As a result, manufacturers must develop capabilities to offer their customers a choice to personalize furniture models according to their preferences.
The Need for Accurate CAD Drawings for Furniture Manufacturers
These challenges point to effective design communication between all the stakeholders involved throughout the manufacturing cycle. That is where furniture CAD drawings developed using AutoCAD, SolidWorks or Inventor come into the picture. With clear and comprehensive furniture drawings, manufacturers can come up with custom furniture pieces with minimal wastage.
Details in Furniture Drawings
Furniture sketches start with the research process. This part involves searching the industry to understand the current trends and check whether there is space for a new concept.
Then comes the actual design, which is initially drawn out as a sketch with less focus on the exact dimensions. Once the design is approved, the following process involves converting the sketch to technical drawings that make manufacturing possible.
Following are some of the essential elements that make up furniture drawings:
Manufacturing detailing
Manufacturing details involve how the different parts of a final furniture piece will be manufactured. It includes the exact dimensions of each part, assembly, and subassemblies. It also has details for manufacturing processes to generate the desired form and function.
Manufacturing detail is crucial because it quickly helps the manufacturer delegate production tasks between different manufacturing processes. Engineering change orders will likely increase with the incomplete manufacturing details, delaying the production cycle.
Design intent
The design intent defines relationships between each furniture part as envisioned by the designer. And 2D drawings and 3D models convey it to the shop floor so that fabricators can identify how the actual furniture piece will look and function.
The benefit of using parametric CAD software is that any change made on the 3D model directly reflects on 2D drawings. In addition, a design intent document also contains technical specifications of the product so that the final assembly follows the exact form and function.
BOMs
A bill of materials (BOM) is a comprehensive list of parts, items, assemblies, subassemblies, intermediate assemblies, documents, drawings, and other materials required to create the furniture.
A BOM helps to calculate the project's overall cost while making it easier to understand how much investment goes into each part. This list can then be used to optimize costs further and gauge the feasibility of the product when scaling the production.
Another vital role of BOM is to help the manufacturer maintain sufficient stock of inventory levels. Since the manufacturer has access to a detailed report on all the parts needed to make the product, it gets easier to place orders.
A BOM contains all the necessary parts, even the most minor component that goes into the final furniture assembly. Therefore, it is one of the essential documents in a manufacturing planning cycle that makes communication easier between manufacturers, suppliers, and floor personnel.
The Role of CAD Software
Modern CAD tools play a vital role in helping furniture manufacturers prepare accurate drawings for effective communication between stakeholders. They ensure that the production is on schedule and with minimal engineering change orders.
3D parametric CAD modeling tools like SolidWorks and Inventor further enhance design communication by enabling a 3D design approach. With 3D even, non-technical teams can visualize and understand the intent better for sharing feedback.
The tools also offer opportunities to apply material properties to the 3D model and extract 3D renderings for end customer reviews. With such powerful visualizing capabilities, marketing and sales teams are better equipped to convince customers and close the potential leads.
Moving Beyond 2D Furniture Drawings with Design Automation
With the 3D design approach, manufacturers get the opportunity to take their design capabilities to a whole new level through automation and product configurator.
Utilizing design automation, furniture manufacturers can automate their design cycles for products that share similar design intent. Using a rule-based approach, they can automatically generate 2D manufacturing drawings, 3D models, and other manufacturing documentation for different variants of the furniture models.
Conclusion
From adopting the current industry trends to addressing the needs of the customers, furniture industry manufacturers need detailed furniture drawings for accuracy. 2D furniture drawings and 3D models with SolidWorks, AutoCAD, or Inventor not only impart accuracy in drafting but also speed up the entire design-to-manufacturing process.
Further, CAD documents for manufacturing custom furniture products streamline the shop floor operations as they reduce the change orders. CAD drawings are developed considering the shop’s tooling capabilities and hence ensure higher efficiencies for furniture manufacturers.
