Hi what is it you are trying to do?
if you wish to bypass Iclones animation tools completely and use a CC3 rig to animate with Blenders Character tools tool then the autorig pro add-on may be a worth while investment.
If you plan to send CC3 figures over to blender and use Iclone created animation
you should use the free Blender autosetup plugin for import
and then follow this tutorial for importing/using multiple Iclone motions
