i'm not sure i know what you mean by ripping. 2.59 is free and stable btw and only takes a few minuets to download and install.

joining works like parenting, only it's control j instead of p. the joined meshes or other objects then behave, for all practical purposes have become, one single object, which may be useful for building complex shapes, but then the same texture is applied to all of it, unless you do different texture on different faces with multi-texture materials thing. (which is easier to understand, from how explictly they're treated seperately, materials and textures, in 2.5x)

There only good for blender 2.49b http://www.youtube.com/watch?v=8w88B7F7v_k and I don't understand how begin one.

well it takes a while to get into it. there's links to a tun of tutorials from the blender.org website. there's also a couple of books you can buy, but yah, most of the documentation you can find is still mostly for 2.49 and earlier. 2.5x groups controls a bit more logically. which means a lot of things are no longer in quite the same place, or done entirely the same way, but most of the old keyboard shortcuts still work and do the same things. with some exceptions of course. there are a lot of really useful new things though. like the sqorus and landscape primatives. and much more complete sculpt support, among other things.

the book "mastering blender" was written before 2.5x was stabilized, but it (2.5x, which is now up to 2.59 and stable) fallows most of what its authors recomended"

Yes one thing problem 2.5 is limit import and export. 2.49b is lot select import and export.

2.5 has them, you just have to go into user preferences to turn them on. it has everything set up so you have to turn it on individually, because a very few of them are still unstable.
there's a tab bar in the preferences dialog box that says "add-ons" on it. click that and you'll find them. then click the check box beside the ones you want to enable. the ones that are unstable have a little warning icon in them to indicate this.

Where can I find Preferences on menu?

There link

ok, you see the little icon in the header of each window that tells you what kind of a window it is, that gives you the menu of what kind of window you want it to be? well, user preferences is now right there on that menu. you can do this with any blender window you have open or open one to do so. the next option above properties is outliner. the next item above outliner is user preferences.

when you open that, you'll see a row of tabs across the top of it. (it comes up in "system"). click on the "add-ons"; its the one in the middle. that comes up in "all" and there you are.
you can then click on "import export". or just scroll down to it.

Thank you for tell me and I find one User Preferences and not really clear direct.

1. very small (object) of menu next to (View, Select, Object)
2. popmenu and click User Preferences
3. ... ... ... etc.

that's it. there you are. with preferences open, there are tabs across the top of it. the one in the middle is "add-ons"

in that you can select every feature you want to enable or disable, all the py scripts that came with it, including all the import and export ones. and a lot of other nice useful things. like the landscape and squorus primatives which i find very useful.

Yes true many thanks.
