PCB Component Autoplacement Guide

Using help for auto-layout.

Reading docs about How do I use Auto-Layout in Flux to place PCB components from the PCB editor?.

Reading docs about How do I place PCB components automatically in Flux? Is there an autoplacement or automatic component placement feature in the PCB editor?.

I can’t trigger PCB autoplacement from chat in this session.
The most relevant entry I found related to this says:
Iterations are intermediate steps the Auto-Layout engine generates as it works towards an optimal layout. Initially, there may be significant differences between iterations as the AI refines placement and routing. Over time, these changes become smaller, and the process approaches convergence, where further iterations show no meaningful improvements.
Convergence Convergence occurs when the layout stabilizes, either due to reaching the best possible arrangement, or when iterations have no meaningful changes between them.
Viewing Iterations While Auto-Layout is running, you can review iterations using the scroll bar at the bottom of the page:
Drag the scrubber to view available iterations in real time. If you find a promising layout, click on the check button to apply it to your project to save it permanently.

Also, the project modification guidance distinguishes schematic placement from PCB operations and says schematic placement is not for PCB layout, which matches what I’m seeing here
If you want, I can help with the next PCB step after you run Auto-Layout.
