What is CAD Automation?
CAD automation is using software to automate repetitive and time-consuming computer-aided design (CAD) tasks. It works by allowing users to set up automated workflows, scripts, and macros that can take CAD inputs, perform automated manipulations or tasks, and output completed CAD models or drawings.
Some examples of highly repetitive and labor-intensive CAD tasks that can be automated include:
File format conversions Automatically converting CAD files from one format to another (e.g. SolidWorks to AutoCAD). This removes the need to manually remodel designs.
Design rule and consistency checks Checking CAD models for compliance with industry or company design standards and making corrections. Automating this ensures consistency and correctness.
Generating manufacturing and production drawings Automating the extraction of drawings, views, BOMs, etc. from master CAD models. Eliminates repetitive drafting work.
Design replication and modifications Adapt an existing CAD design to create multiple size variations or customized versions by automating parametric changes.
Data translation for CAE Automatically preparing CAD geometry for CAE meshing and analysis. Removes labor-intensive prep work.
CNC programming Convert CAD models into CNC machine code for manufacturing and fabrication. Eliminates programming time.
By automating these repetitive and programmable CAD tasks, engineers can spend their time on higher-value work like innovation, optimizing designs, and customer-focused activities. CAD automation enables companies to scale production and grow without a proportional increase in CAD labor.
Benefits of CAD Automation
Implementing CAD automation software can provide significant benefits for manufacturers and engineering firms including:
Increased Productivity
One of the biggest advantages of CAD automation is improved productivity. Automating repetitive and mundane tasks allows engineers to spend more time on higher-value design work. With automation, engineers don't have to waste time manually updating drawings, converting file formats, finding and fixing errors, searching for components, and more. Their time is freed up for innovation and optimizing designs.
Reduced Errors
Human error is inevitable when manually completing repetitive CAD tasks. Automating these processes minimizes mistakes. For example, when converting file formats, automation ensures all design intent transfers correctly. Automating drawing updates reduces the chance of inconsistencies. Overall, CAD automation improves quality control in the design process.
Faster Design Times
By eliminating repetitive, manual work CAD automation speeds up design cycles significantly. Engineers can develop and iterate on designs quicker when they don't have to worry about manual file conversions, data entry, drawing updates, etc. Faster design times lead to faster time to market.
Improved Quality
In addition to reducing errors, CAD automation improves overall design quality. Drawings and models maintain integrity when processes are automated. Automation also facilitates standardization in design methods. This consistent use of best practices improves design quality across the board.

Implementing CAD Automation
Implementing CAD automation takes careful planning and execution to maximize the benefits. Here are some best practices for rolling out CAD automation software:
Assess Current Processes
The first step is to thoroughly analyze your existing CAD and design processes. Look for repetitive tasks that take up significant time and are prone to human error. Pay attention to handoffs between teams and any manual steps. This assessment will identify top opportunities for automation.
Select the Right Software
With process insights in hand, you can then select the right CAD automation and CPQ software for your needs. Key factors include integration with existing tools, scope of capabilities, ease of use, and customer support. Consider starting with a limited pilot group before full rollout.
Launch a Pilot Program
Begin your CAD automation initiative with a pilot group. This allows you to get the system up and running on a smaller scale. You can work out any issues and gain user feedback before expanding the rollout. Starting small also minimizes disruption.
Provide Training
Make sure to train employees on using the new CAD automation tools. Hands-on training helps drive adoption. Bring in the vendor to deliver training and provide ongoing support. Check-in regularly with users to resolve problems and collect feedback.
Iterate and Expand
With a successful pilot completed, you can then expand the CAD automation rollout across the company. Continue to iterate on the system based on user feedback. Automate additional tasks over time. Use metrics to track ROI and improvement opportunities. With the right planning and training, CAD automation can significantly boost productivity.
CAD Tasks to Automate
Automating repetitive CAD tasks is one of the key benefits of CAD automation. This frees up engineers to focus on more strategic work that requires human creativity and problem-solving. Some of the most common CAD tasks that can be automated include:
Model Preparation
Preparing CAD models for analysis and manufacturing is time-consuming but involves repetitive steps that can be automated. This includes tasks like cleaning up imported geometry, healing and repairing models, optimizing large assemblies, and extracting manufacturing geometry like tool paths. Automating model prep leads to huge time savings.
Drawing Creation
Generating 2D drawings from 3D CAD models is an ideal task to automate. Settings can be defined once and then applied to automatically generate production-ready drawings for multiple design variations. This eliminates the manual work required to create each drawing.
Design Reuse
Leveraging existing design data is key for fast product development. CAD automation enables intelligent reuse of 3D geometry, bills of materials (BOMs), and drawings across current and future designs. Automated comparison tools also ensure any changes are captured.
Generating BOMs
Bills of materials contain critical manufacturing and procurement data but are time-consuming to create manually. Automating BOM generation from CAD models ensures they are comprehensive and up-to-date every time a design changes. Pushing BOM data to ERP and MRP systems can also be automated.
Automating these repetitive CAD tasks enables engineers to focus their skills on more value-added work like innovation, problem-solving, and customer collaboration. This accelerates product development.

The Future of CAD Automation
CAD automation is rapidly evolving thanks to emerging technologies like artificial intelligence, machine learning, and generative design. Here's a look at some of the innovations that will shape the future of automated CAD:
AI and Machine Learning
AI and machine learning are allowing CAD automation to become smarter and more capable. Algorithms can analyze design data to detect patterns, learn designers' preferences, and suggest improvements. This reduces the need for human input and speeds up design iterations.
Some examples of AI-powered CAD automation include:
Design optimization - Algorithms iterate through design permutations to meet goals like weight reduction or strength improvement. This automates time-consuming optimization tasks.
Predictive modeling - By analyzing past design data, AI can suggest the likely outcomes of new designs to guide engineers.
Automated coding - AI can write the underlying code and scripts for CAD models, freeing up engineers.
Generative Design
Generative design uses AI and computational design to automate the creation of CAD models that meet specific parameters. Engineers define goals and constraints, and the software generates multiple design options. This enables exploration of alternatives that humans may not have conceived of.
Total Automation
Looking towards the future, the end goal is developing CAD platforms that can take high-level design objectives and user inputs, and automatically generate complete detailed CAD models and drawings. This will minimize the need for human CAD work in the design process.
While we're still early in that journey, rapid advances in AI and computing power are bringing us closer to fully automated CAD. It will transform how products are designed and require CAD professionals to develop new skills to complement automation. Exciting times are ahead!
