Hello José

I had take a look to the geoprocessing tools, especialy to clip function.
But the functions are mostly used for complete layers, i know that also
selected objects can be clipped against each other, but the result is a new
layer, which would produce a hugh amount of files which must be brought
together at the end of digitizing job. I am not very sure what happend to
the unselected objects in the layers which i want clip against each other.
Thank you a lot for fast answer.
At which time this function would be integrated within these great software
?

Marco
