LAD (Language-Aided Designer)

A SolidWorks add-in to design with natural language using AI

Describe your design in plain language and LAD will translate it into SolidWorks operations, creating sketches, features, and assemblies all through natural conversation. LAD uses screenshots and the feature tree to understand your model's current state, verifying operations were completed correctly and correcting mistakes.

Design from Documentation and Images

Provide documentation files, images, or examples of previous parts and assemblies, and LAD will intelligently read and use them.

Write and Run Macros

LAD can write and run VBA macros for reproducibility and niche functionality not covered by standard LAD tools. When writing macros, LAD searches SolidWorks documentation and examples to better understand the API.

Permissioning and Versioning

LAD stores checkpoints so you can revert unwanted changes, lets you control which commands run automatically, and uses rules you provide to guide the AI as it works.

Questions & Answers

LAD (Language-Aided Designer) is a system that integrates directly into SolidWorks as an Add-in and can create sketches, features, macros, and other CAD objects.
