Hello,

How difficult would it be to extend v.extract to allow extraction of all vectors in the current region ?

to extract vectors which overlaps the current region would quite easy.
You mean to avoid using

v.in.region
v.overlay operator=and

?

That's it. Should have thought of that myself. Thanks !

Would be a little plus to have it directly in v.extract, but it's sufficient for me now.

v.select too. (doesn't modify areas at region boundary)
