Automatic uv island from hard edge

Alecc

Hey guys

I need to create a uv island from my hard edge model. 
I don't know if my request mean something... 
In other word  i would like to create a uv island, each time there is an hard edge  
A script exist for maya, but I don't find for 3dsmax.
I tried Textools, without result

Have an idea  

Thanks
