I have seen many maps made for portal and wondered What Program should I use to map:?: And What is the best tutorial for mapping for portal:?:

Any Help will be rewarded with a companion cube.

also there is a search button at the top of the page
and its a good idea to do some leg work before posting on this forum, we are a very friendly community but don't take too kindly to laziness... from the man himself

As it has been stated probably 100 times or more here, this is honestly not the best place to start if you have never done any sort of Source mapping before. If you are a complete newbie to Hammer, I would recommend visiting sites like Interlopers or Halfwit-2 and reading the tutorials they have there. We are centered around Portal specifically, not about how to do the basics. Sorry.
