One reason for not removing the dials is that even when removed, they still work. If you remove all the rotate dials, a user can still rotate with the tools. If you set limits to zero, you can ensure that nothing can be rotated by accident, which is much safer. If you don't want to see the dials in poser, just change the line 'hidden 0' to 'hidden 1' in each channel you want to hide. Although, I personally like to leave the user as many options as possible. You can never tell what someone, somewhere will want to do. mac
