LLMs and CAD: Can AI Design Our Future?

Large Language Models (LLMs) like ChatGPT and DeepSeek have been showing off their talents across various fields. Yet, until now, we've not seen a thorough review of how these models mesh with Computer-Aided Design (CAD). CAD is the backbone of 3D modeling, important for designing everything from consumer gadgets to industrial machinery. With designs getting more complicated, the idea of LLMs enhancing CAD workflows is tantalizing. But are they ready to deliver? Or are they just the latest AI buzzword?

The CAD Conundrum

CAD is no small player. It's the industry standard for 3D modeling and a powerhouse in product design. As technology evolves, the demands on CAD systems increase, pushing complexity to new heights. Enter LLMs, offering a supposed edge to simplify and innovate. The question is: can they live up to the promise? Show me the product that proves LLMs can enhance these workflows, and I'm in. Until then, skepticism remains my default setting.

LLMs: The Good, the Bad, and the Closed Source

Understanding LLMs is important before integrating them into CAD. The survey dives into both closed-source giants and open models, examining their core foundations. While many tout the wonders of closed-source models, open-source options are gaining ground, offering transparency and adaptability. But let's be real. If these models don't translate into tangible improvements in CAD, they're just shiny toys in a toolbox.

Applications and Future Directions

The review identifies six key areas where LLMs could impact CAD significantly. From automating repetitive tasks to simulating complex scenarios, the potential is undeniable. However, potential doesn't always equal product-market fit. Will these advancements reduce design churn or just add another layer of complexity?

Looking ahead, the roadmap for LLMs in CAD is full of possibilities. Future directions are proposed, painting a picture of endless innovation. But I'd wager that until we see retention numbers proving LLMs' worth in CAD workflows, it's all just speculation.

So, what does this mean for the future of design? Are we on the brink of a revolution, or is it just another week, another AI wrapper? The jury is still out, but it's a storyline worth watching.
