This is what the Flux documentation says about Smart Vias:
"Overview
In traditional PCB design, designers are required to select the appropriate via type for each connection, which can be challenging and prone to errors, especially in multi-layered boards. Flux simplifies this process by automatically determining the optimal via configurations and applying them where needed.
For example, if you need to connect a trace from mid-layer 2 to the top copper layer, Flux's Smart Vias feature allows you to select the start and end layers, and it will automatically place the necessary vias and adjust the layout
Wirelessly connects nets on schematic. Used to organize schematics and separate functional blocks. To wirelessly connect net portals, give them same designator. #portal
