How to use Pad Class?

lamabrew

I haven't turned up an explanation for this by searching (even in Designer). Apologies if I missed the obvious answer.

 

I want to assign a pad class to certain pins of a component so that the PCB tools knows how to connect it to a polygon. In this specific case the connector has multiple ground (shell) pins and I want them directly tied to the GND plane and not with thermal reliefs.

 

So far all I have been able to do is manually add the connector pins in PCB Class dialog. What I want to do is attach a Pad Class property to the PCB footprint in the library, or in the pin property for the part (I'm using integrated library and there is a 1:1 symbol to footprint correspondence).

 

I thought maybe after setting the pad class in PCB I could back annotate to the schematic and see what it was doing, but CS doesn't see adding a pad class as something that affects the schematic as it tells me there's nothing to do. I tried adding parameter to the pin for the component and updating in the forward direction but again CS says there's nothing to update.

 

There doesn't seem to be anything like the Directives->Net Class from the schematic side for setting Pad Class?

    Sorry but I could not find a solution, there doesn't seem to be a way to set up pad classes in libraries or similar.
