[GRASS-user] How to do vector elaboration only in active region

Hi all,
I am trying to use some vector operations in GRASS.
I can not understand what I am missing but it happens to me that the vector commands works on all the vector data instead of working only in the active region. I am wrong or is it so, and if so is there in GRASS the possibility to create a new vector data cropping the original one on the active region?

Thanks in advance for help

One solution that I have found to crop vectors to the region:
1)Crate a region box with v.in.region
2)Crop with v.overlay operator=and

Thank you Pablo,
unfortunately my vector is a point layer and v.overlay works only with lines and areas... :frowning:

Try v.select:
