You mentioned benchmarks don’t mean much in this area. What are the best models you found in this area?

Personally, I’ve had the most success with GPT models using MCP servers for this task.

Surprisingly Gemini models. Spatial understanding seems to be the best for the price and speed.

Same here. 5.5 would sometimes oneshot relatively complex models even without MCP. Opus, however, even with Fusion 360 MCP access would usually make comically bad models. It seemed that Opus tried to reason through the problem while GPT would come up with a general plan of using whatever tools were available to solve the problem. In chat, it would use the available Python and trimesh. It was also the only time I had ChatGPT work on something for over 30 min without giving up.
