Hi. A new Problem have found:
Why he masked out me also the other Side of my Model?
See:

I´m not sure about your doubt. All Masking from rectangle, circle, curves etc will be all around your model including backfaces as allways. If you don´t want that to happen you can Hide your back part of the mesh and draw again your rect mask
AaaAh yeah, thx. That works. Nice, thanks…
