What you can do

Function

AI assistant

Written by a model from the evidence it cites · not reviewed

Answers use only what was read of this design: its BOM lines, the function hits, the parsed nets around your selection and the part's catalogue record. Every statement links to its evidence.

The AI assistant is not available here: no model is set up for it. The design, its BOM and the viewer work as usual.
