How do i get a model that already exists and edit it?

ok for all of u that done know me, i am slowly teaching myself how to 3d model, i am fairly good at modeling, i havn't begun 2 learn how to animate, and i resently figured out to do the VERY basics of uvw mapping, anyone that could help me figure out the alpha channel stuff in the Billizard art tools documentation and what they mean by "fine tuning ur uvwmaping" (how do i fine tune, to best of my knowledge only way i know how 2 uvwmap is spherical mapping, i would love to be able 2 do certain parts of the maping by hand, but i have no idea how 2 begin to do this... anyway) i just need to find the model files for all the units that are in the game, specifically the mine cart and the wheelborrow, i need to make them face the right angle, and make it so that they are well away from the origin, i am going 2 be attaching them to mules, so they need to not be inside the mule... anyone that can help in any way plz do, i will be ur best friend (lol)

thanks in advance :>

Edit: ARG sorry for putting in wrong forum, this new stuff is annoying visually 2 me, im still getting used 2 it, sorry. This should be in requests area i think.

Is this what your looking for? If not I suggest you get the program Warcraft III Viewer, you can export models, skins, etc from Warcraft III itself with that program. You should find it in the downloads section.

Ahhh thank u very much, thats all i needed, ill get to work right away :P
