Have you looked at this >> http://www.pixologic.com/docs/index.php/Tool:Masking_Subpalette

Thanks dear, but I know about the mask, but I can use these mask just in the subtools, not in the main tool. I am not sure why is disabled that option.

Looks like your model needs UVs.
You should ask things like that in the Questions+Troubleshooting section btw.

Thanks, and I have found the problem. that is because when we add dynamesh, it disable this option.
