Refueling altitude is typically around 25000 feet (there are various altitudes, but that is a good generic one). The airplane tracks around a left turning oval, example length of straight track would be 34 nautical miles, separation of tracks (two sides of the oval) 14 NM. Speed would be around 310 knots for a KC135.
Of course the Air Force (F15) and Navy (F18) have different refueling systems. Air Force uses the boom as shown in brunobellic's picture. The to be refueled plane position itself, then the boom controller in the tanker maneuvers the boom into the refueling trap.
For Navy planes, there is either a drogue attached to the plane, or a drogue adapter attached to the boom of an Air Force Tanker. The drogue is tracking and the fighter pilots drives the plane refueling probe into the basket.
PS: Hit me if someone needs a modeling done of the drogue basket.
I think since this is purely artificial, that this is fine as is, it's close enough, and since one cannot deploy the probe on the F18 (AFAIK) then it doesn't matter that there is a proper basket, the boom will do. Just approach and fly close, and we'll call it "refueled".
