If what you are saying is that you would like to catch a swarm from your own hive then you will need a lot of luck - it does happen but it's by no means a certainty. The catching of swarms is pretty much a matter of luck - I find that one or two arrive in my front garden, more or less in the same vicinity, every year and they are certainly not from my hives.
Perhaps read this:
Bees and Energy (Ley?) Lines
However, if all you want to do is make increase and you have an existing colony it's very easy to make another colony from the one you have ... rather than waiting for them to swam you can either wait until you find a queen cell (or ten !) in your hive and split them or just split the colony and the queenless half will make a queen cell or few and bob's yer uncle you have another colony (assuming that the newly created queen gets mated).
Looking back over your posts it looks like you have come into the craft after a course 10 years ago and taken delivery of a Nuc in January ... it's time for a bit of reading - Did you get hold of a copy of the Haynes Manual of Beekeeping because you are going to need it shortly.
