Show HN: AI in SolidWorks
Show HN: AI in SolidWorks Hey HN! We’re Will and Jorge, and we’ve built LAD (Language-Aided Design), a SolidWorks add-in that uses LLMs to create sketches, features, assemblies, and macros from conversational inputs (<a href="https://www.trylad.com/" rel="nofollow">https://www.trylad.com/</a>).<p>We come from software engineering backgrounds where tools like Claude Code and Cursor have come to dominate, but when poking around CAD systems a few months back we realized there's no way to go from a text prompt input to a modeling output in any of the major CAD systems. In our testing, the LLMs aren't as good at making 3D objects as they are are writing code, but we think they'll get a lot better in the upcoming months and years.<p>To bridge this gap, we've created LAD, an add-in in SolidWorks to turn conversational input and uploaded documents/images into parts, assemblies, and macros. It includes:<p>- Dozens of tools the LLM can call to create sketches, features, and other objects in parts.<p>- Assembly tools the LLM can call to turn parts into assemblies.<p>- File system tools the LLM can use to create, save, search, and read SolidWorks files and documentation.<p>- Macro writing/running tools plus a SolidWorks API documentation search so the LLM can use macros.<p>- Automatic screenshots and feature tree parsing to provide the LLM context on the current state.<p>- Checkpointing to roll back unwanted edits and permissioning to determine which commands wait for user permission.<p>You can try LAD at <a href="https://www.trylad.com/" rel="nofollow">https://www.trylad.com/</a> and let us know what features would make it more useful for your work. To be honest, the LLMs aren't great at CAD right now, but we're mostly curious to hear if people would want and use this if it worked well.

Show HN: I built an 8-bit CPU simulator in Python from scratch
Show HN: I built an 8-bit CPU simulator in Python from scratch I built a tiny 8-bit CPU simulator in Python to better understand how computers work at a low level. It visualizes registers, memory, and instructions in real-time, so you can actually see each operation as it happens. You can write simple assembly code and watch how the CPU executes it step by step.<p>The project is mainly for learning and experimentation, but I’d love feedback or ideas for improvement.
