What CAD software have you used for designing hardware components?

IoT Hardware Developer Interview Questions

Sample answer to the question

I have used AutoCAD and SolidWorks for designing hardware components. In my previous role, I used AutoCAD to create detailed 2D drawings of electronic circuits and PCB layouts. I also utilized SolidWorks to design 3D models of hardware components and enclosures. These tools helped me visualize and optimize the layout and placement of components, ensuring compatibility and functionality. By using CAD software, I was able to streamline the design process and improve the overall efficiency of the hardware development.

A more solid answer

Throughout my career, I have gained proficiency in using both AutoCAD and SolidWorks for designing hardware components. In my previous role as an Electrical Engineer at XYZ Company, I used AutoCAD extensively to create detailed 2D drawings of electronic circuits and PCB layouts. This allowed me to accurately visualize the connections and placements of components. Additionally, I utilized SolidWorks for 3D modeling of hardware components and enclosures. I used its features to optimize the designs for manufacturability and functionality. For example, I created 3D models of enclosures to ensure proper fit and mechanical compatibility with other components. These CAD tools helped streamline the design process, reducing errors and improving overall efficiency in hardware development.
