I'm thinking this should be in the maps forum, and I cannot quite understand what you are asking.
If your wondering on how to attach weapons to models in maps through attachment points, it would belong in the map section.
If your wondering on how to make weapon attachment points on models, I can help you if you are using the Art Tools and 3dsMax5. Create a simple geometry (a 10x10x10 box is what I use), goto the Utilities Tab, click more, then User Defined Properties. Expand the Geometry Setting (I forget what it is called, I believe it is the third from the top), and click attachment points. Give it a name appropriate to the position it is at.
