The air-conditioning industry is highly competitive, with a constantly evolving market environment. As a result, the requirements for the CAD design and production cycle have become more demanding for air-conditioning companies. Engineers in this field often face challenges when customer demands change, leading to adjustments in product specifications. Specifically, the lengths and number of rows of the left and right side panels of the air conditioner coil must be synchronized, while other dimensions remain largely fixed. If the CAD software can be driven directly by dimensional variables during 3D CAD design, it would significantly speed up the process of designing side panels.
Today, Xiao Bian has invited design engineers from Guangdong Gaocun Air Conditioning Company to share their experience. They demonstrated how design engineers in the air-conditioning industry use the associative driving functions of well-known 3D CAD/CAM software in China to achieve quick and efficient design solutions.
In the first step, they created a new document and selected "Insert" from the menu bar. A dialog box appeared where they input variable symbols and expressions. By setting up these relationships, they could create additional variables as needed. This allowed them to define step values and manage the design parameters effectively.
Next, they drew a sketch rectangle and assigned the required variable to the length (L1). By associating the length with the variable, any changes to L1 would automatically update the design. This not only improved efficiency but also reduced the extra steps involved in manual adjustments.
Then, they stretched the rectangular frame and used the stretched surface as a reference to draw the sketch of a concave hole. The size of the hole was set using the same variable system. They also applied an array variable to control the number of holes, ensuring that any changes in length would automatically adjust the position and spacing of the holes.
By modifying the variable L1, the lateral positioning of the concave holes was dynamically driven. This made it easy to create products of different specifications based on the design requirements, as shown in the final output.
Through this case study, it's clear that Zhongwang 3D’s parameter variable functionality helps engineers improve both the efficiency and accuracy of 3D CAD design. It enables faster transitions from design to production, reducing the impact of market demand fluctuations on the design cycle.
