Designator to a solid region polygon

[benji54]

Hi everyone,
I'm doing a footprint of a USB connector like this:

As you can see there is a Land NO.3 which is supposed to be conected to gnd I guess. To do this, I use Snap points and use a solid region (Place->Solid region)
My problem is I can't assign a designator like a pin. So I tried to put a SMD PAD over the solid region, but in my design it's considered as a problem as you can see:



Thank you very much

Ok, I find the way to do it:
Design->Netlist->Update free primitive
And the error disappears.
I don't really understand If i did it correctly, what was the problem and what "Update free primitive" does...
