Ok because Piktor made a tutorial on makinjg curved meshes with Wings 3d, i wanted to do this.

1. Make a cube any size.



2. Now go to select. And make sure your on faces.



3. Now select one side of the cube.



4. Go to Extrude.



5. Now move the face on the cube. The extrude tool will make a new face every single time you move it.



6. Now go back to select, and then uncheck "ignore backfaces" and go to select verticies. Then select whats in the picture below.



7. Now rotate a bit so its on an angle.



8. Now move the selected area up a bit.



9. Now repeat steps 6-8 to get a curve like this one:

Thanks for this! =3

steps 6 till 9 are best done with rotating arround 0,0,0 so all are the same.(rotate from origin)
In the menutab you also find extrude edges wich works similar but with more options.

Default extrude also removes any bone assignments you may have had on the selected faces. At least it does for me (on both my computers)
