Hi everyone, I could be wrong, but I thought they were asking how to use an object to clip another object in the same layer. Ftools can only use all the objects in a layer to clip all the objects in a different layer, producing a new layer. This can obviously still be used to achieve the desired outcome, but it will require the use of several temporary files and copying and pasting objects between files. It would be very nice if features like clipping were implemented kind of as advanced digitising features, so they could operate with/on selected features. But I imagine this would need a reasonable amount of work from someone. Alister
