What is Design Automation, and How Can You Make The Most of it?

Modern architecture and engineering projects are complex endeavors that require a significant amount of human resources. However, as we progress further into the digital age, we are seeing the release of more tools designed to automate tedious processes and make designing projects and structures simpler than ever.

In this article, we will explain design automation, how to implement it, and how it can give design and engineering firms a competitive advantage by cutting costs and reducing turnaround times.

Understanding Design Automation

Design automation involves using software tools and systems to automate repetitive tasks in the design process typically executed by CAD technicians. These tools, often referred to as Electronic Design Automation (EDA), allow for the creation, modification, analysis, and optimization of designs with minimal human intervention.

Popular design automation tools that facilitate EDA include Autodesk products like AutoCAD and Revit, as well as CadWorks by SolidWorks. In applications like custom product development and automotive design, electronic design automation has the potential to streamline design workflows by significant margins.

AI (artificial intelligence) and machine learning have also become integral to modern design automation. These technologies help maximize efficiency and minimize errors by enabling predictive analysis and intelligent decision-making. By learning from past designs and continuously improving, AI-driven design automation tools can provide more accurate and optimized solutions, further enhancing productivity and reducing the likelihood of costly mistakes.

Key Components of Design Automation

While design automation will vary from firm to firm, generally, there are five key components of effective EDA: CAD customization, rule-based automation, API integration, parametric modeling, and automated documentation.

• CAD Customization: This involves tailoring CAD software to fit your specific project needs and simplify the product development process. Tools like Siemens NX X Design allow users to automate routine tasks and create custom scripts and macros, enhancing productivity and accuracy.
• Rule-Based Automation: Though EDA aims to minimize the human element of design, automated systems still need to be taught how to think. Doing so involves Implementing rules and logic to facilitate computer-made design decisions. For instance, most CAD software programs enable the creation of rule-based models where parameters and components adjust automatically based on predefined rules.
• API Integration: Application programming interfaces, or APIs, allow seamless integration of design automation tools with other systems, such as ERP (enterprise resource planning) and PLM (project lifecycle management) software. This integration ensures consistent data flow and enhances collaboration across different platforms.
• Parametric Modeling: Parametric models are design elements linked together by relationships and constraints. When one part of the model or drawing changes, other similar elements automatically update, reducing errors.

Parametric modeling often exists within BIM (building information modeling). For example, in Autodesk Revit, parametric model groups are called families, which can be created, imported, or modified at any point in the design process to ensure consistency.

• Automated Documentation: EDAs can automatically generate detailed design documentation, including drawings, BOMs (bill of materials), and assembly instructions. This feature significantly reduces manual effort and helps guarantee accuracy.

How to Implement Design Automation

Successfully implementing design automation into a design workflow requires a strategic approach. Here are five steps engineering teams can take to get started with EDA.

Step 1: Assess Your Current Design Process

Start by evaluating your existing design workflows to identify areas that can benefit from automation. This assessment should include:

• Mapping Current Processes: Document each step in your design workflows, focusing on repetitive tasks that could be automated.
• Identifying Pain Points: Determine which time-consuming tasks or inefficiencies could benefit the most from electronic design automation.

Step 2: Choose the Right Tools

Selecting appropriate design automation tools can make or break design automation. Before purchasing software, consider the following:

• Industry-Specific Solutions: Choose tools that cater to your industry’s specific needs. For example, Autodesk’s Design Automation API is excellent for automating AutoCAD and Inventor designs, making it ideal for product development.
• Customization Capabilities: Ensure the tools you’re considering support custom scripts, macros, and rule-based automation so you can tailor them to your specific needs.
• Integration: Opt for tools that seamlessly integrate with your existing software systems, ensuring a smooth data flow and enhanced collaboration.

Step 3: Develop Custom Automation Scripts

Custom automation scripts are central to CAD customization. Start with the following steps:

• Define Automation Goals: Clearly outline the tasks you want to automate and the desired outcomes.
• Leverage Built-In Tools: Use built-in tools and features of your chosen software, such as the DriveWorks Solo, for rule-based design automation in SolidWorks.
• Custom Scripting: Create custom scripts using programming languages like Python or VBScript to automate specific tasks within your CAD software.

Step 4: Train Your Team

Training your engineers and CAD technicians is crucial for successfully implementing design automation. An effective training program includes:

• Hands-On Training Sessions: Conduct practical training sessions focused on using the new tools and custom scripts.
• Continuous Learning: Provide access to ongoing training resources, including online courses, webinars, and user forums, to keep your team updated with the latest advancements.

Step 5: Implement, Monitor, and Optimize

Deploy your automation tools and continuously monitor their performance. Key actions include:

• Pilot Projects: Start with pilot projects to test and refine your automation processes.
• Collect Feedback: Gather feedback from users to identify areas for improvement and make necessary adjustments.
• Optimize Workflows: Use data analytics to optimize and refine automated workflows continually.

Benefits of Design Automation

Design automation offers numerous benefits specific to the design and engineering fields. By integrating advanced tools and technologies into your daily workflows, you can significantly enhance the efficiency, accuracy, and scalability of your projects.

• Increased Efficiency: Automating repetitive tasks significantly reduces design time and effort, allowing engineers to focus on innovative aspects.
• Better Accuracy: Rule-based and parametric modeling ensures consistency and accuracy, reducing errors in design outputs.
• Cost Savings: By minimizing manual effort and optimizing workflows, design automation leads to significant cost savings.
• Rapid Prototyping: Automated tools enable quick iteration and prototyping, accelerating the design process and time-to-market.
• Scalability: Automation tools can easily scale to accommodate complex and large-scale projects without compromising efficiency.

Maximize Output Potential with Design Automation

Design automation, with its focus on CAD customization, has the potential to maximize the output of digitally designed products. One study published by SolidWorks suggested that by implementing EDA and standardizing CAD practices, some product manufacturers could accept roughly 30% more orders.
