Will and Jorge have introduced LAD (Language-Aided Design), a new SolidWorks add-in that utilizes LLMs to translate conversational inputs into complex modeling operations. Recognizing a gap in the CAD market where text prompts cannot directly generate 3D objects, this tool bridges the divide between natural language and design execution. LAD functions by calling specific tools to create sketches, features, and assemblies, while also managing file systems and writing VBA macros. It provides context to the AI by parsing feature trees and capturing automatic screenshots, allowing for a conversational workflow that understands the current state of a model.

The system includes safety features like permissioning and checkpointing to revert unwanted edits. This development is significant for SolidWorks users and the broader CAD industry, as it aims to democratize design by reducing the steep learning curve associated with traditional modeling interfaces. It affects mechanical engineers and designers by potentially accelerating the prototyping phase, while also posing questions about the future role of manual command execution in engineering.

The tool is currently available for download on Windows.
