Mh if you look for other tools:
There are lots of 3d modeling tools. I give you a list of them:
1. 3ds max (very expensive, but very functional tool (VERY), Version 4-5 support warcraft art tools)
2. Gmax (light version of 3ds max, free (register needed but free), not as functional as 3ds max but still good, lots of good tutorials)
3. milkshape (not free but not expensive, GREAT tool for wc3 modeling, many tutorials)
4. Blender (open source, HUGE number of tutorials, GREAT tool, but i never saw anybody using it to create wc3 models...)
Maybe that gives you a little overview.
I would really try to use blender. If it does not work with wc3 use gmax
