Please does exist some basic start tutorials how to make that maps?? another guestion does exist some export import to 3ds max and how can i decomprimate bsp file. Please can somebody help me with starting thank you very much

Well for mapping you must download the Source SDK from steam. After that open up Source SDK and double click on the SDK reference docs. They have a good starting tutorial. Further knowledge can be found there or here in the tutorials section.

I don't really understand the second question. It's another thing you're going to have to learn if you want to continue to post here. You need to take the extra time to make your posts legible, it helps people help you.

As far as I can guess though; Export your 3ds max creation to Milkshape and then to HL2. Or get XSI and the Valve addon.

Enjoy your stay here at the Snarkpit!

If you can wait another week or so I will start realesing a 3 or 4 part newbie first map tutorial.
