SW PCB: linking NET between schematic and design?

 Hello community, I hope to wake up the few electronics engineers who sleep there.

I'm starting out on Solidworks PCB (2020). I created my schematic (*. SchDoc), but in the PCB design document (*. SWPcbDoc) no NET class appears.

Why aren't the NET classes in my schematic automatically bound to the project's PCB? What do I need to do to link the 2 documents?

Thank you

I finally found the solution;

Home tab > Project > Import changes from *. PrjPcb then [Validate changes] and finally [Execute changes].

The NETs and components are then imported onto the document.

A word to the wise.
