I Did Not Write This Blog Post



ChatGPT did. Well, let me back up; I’m writing the introduction and the AI wrote the rest. I started by asking, “Can you help me write a blog post?” It responded with some generically helpful tips to write a post. Not interesting. So, I prompted it with,

Clip art, at the first, was taken as a modest threat to commercial artists. Now, stunning art and effective logos can be produced incredible quickly by generative computing. I wonder how my profession in mechanical engineering and 3D CAD will be affected by these new technologies?

It responded with some cheeri-o optimism about how our jobs are not dead, that we professionals “bring a unique set of skills, knowledge, and experience to the table,” and that it is important to “stay up to date on developments in technology and be willing to adapt and learn new skills.” Also boring. But I kept digging. I messed around with it for hours. Then I asked it to write it up as a blog post. This is what it wrote (I stitched the pieces together):


Using AI and ML to Enhance Mechanical Engineering and 3D CAD


In recent years, artificial intelligence (AI) and machine learning (ML) have become increasingly important in the field of mechanical engineering and 3D computer-aided design (CAD). These technologies have the potential to streamline the design process, optimize designs for specific purposes, and automate repetitive tasks, freeing up engineers and designers to focus on more complex and creative work. In this post, we will explore some of the tools and technologies that can be used to enhance the work of mechanical engineers and 3D CAD designers.

There are a number of tools and technologies that can be used to automate tasks and optimize designs in mechanical engineering and 3D CAD. One such tool is deep learning frameworks, such as TensorFlow, PyTorch, and Keras. These frameworks can be used to build and train neural networks that can recognize patterns and make predictions based on data. For example, you could use a neural network trained with these frameworks to predict the properties of different plastic materials based on their chemical composition, or to predict the performance of a plastic part under different load conditions.

Another tool that can be used to optimize designs is neural network libraries. Neural network libraries are software libraries that provide pre-built neural network architectures and algorithms that can be used to develop custom neural network models. They can be used to optimize designs in a number of ways, such as:

  • Predicting the properties of different materials: Neural network libraries can be used to build a model that predicts the properties of different materials based on their chemical composition. This can be useful for selecting materials that have the desired properties for a specific application.

  • Optimizing the design of a product: Neural network libraries can be used to optimize the design of a product for a specific purpose, such as minimizing weight or maximizing strength. This can be done using techniques such as genetic algorithms, which involve using a computer program to generate and evaluate multiple design options in order to find the best one.

  • Automating tasks: Neural network libraries can be used to automate tasks such as creating drawings or generating part lists. This can be done using techniques such as machine learning, which involves training a computer program to recognize patterns and make decisions based on data.

Some examples of neural network libraries that can be used for these purposes include scikit-learn and Theano. These libraries are open source and widely used in the field of machine learning, and they provide a range of algorithms and tools that can be used to develop custom neural network models.


Google Cloud Vision and Amazon Rekognition are neural network APIs that provide pre-trained models for tasks such as image recognition and object detection. While these APIs are primarily designed for analyzing images and extracting information from them, they could potentially be used as part of a workflow to design the physical geometry of a plastic part. Here are a few examples of how this could be done:

  • Analyzing reference images: You could use Google Cloud Vision or Amazon Rekognition to analyze reference images of the plastic part you want to design, and extract information such as dimensions, surface features, and any other relevant details. This information could be used to create a digital model of the part, which could then be used as a starting point for further design work.

  • Identifying design errors: You could use these APIs to analyze images of a digital model of the plastic part, and identify any errors or deviations from the desired design. For example, you might use the API to detect if the part has any defects, such as cracks or warping, or if it does not meet the required specifications. This information could be used to modify the design and improve its performance.

  • Generating alternative designs: You could use these APIs to generate alternative designs for the plastic part based on a set of criteria or design constraints. For example, you might use the API to create a set of designs that minimize weight or maximize strength, and then evaluate these designs to determine the best one.

In this post, we have explored the ways in which artificial intelligence (AI) and machine learning (ML) can be used to enhance the work of mechanical engineers and 3D computer-aided design (CAD) designers. We have discussed a number of tools and technologies that can be used for this purpose, including deep learning frameworks, neural network libraries, and neural network APIs. These tools can be used to automate tasks, optimize designs for specific purposes, and predict the properties of different materials, among other things.

In particular, we have discussed how neural network APIs such as Google Cloud Vision and Amazon Rekognition could potentially be used as part of a workflow to design the physical geometry of a plastic part. These APIs can be used to analyze reference images, identify design errors, and generate alternative designs based on specific criteria.

Overall, the use of AI and ML in mechanical engineering and 3D CAD is a rapidly evolving field with great potential to enhance the work of these professionals. By staying up to date on developments in these technologies and learning how to use them effectively, mechanical engineers and 3D CAD designers can unlock new possibilities and stay ahead of the curve in their fields.
