[Portugal] Re: Fw: duvida com edição de vectores

Venina...

Isso é feito mais facilmente... se percebi bem o que pretendes...

"The option "Enable topological 
editing" is for editing and maintaining common boundaries in polygon 
mosaics. QGIS "detects" a shared boundary in a polygon mosaic and you 
only have to move the vertex once and QGIS would take care about 
updating the other boundary. 

There is also another option that avoids overlaps in polygon mosaics, 
called "Avoid intersection of new polygons". It is for quicker 
digitizing of adjacent polygons. If you already have one polygon, it is 
possible with this option to digitise the second one such that both 
intersect and qgis then cuts the second polygon to the common boundary. 
The advantage is that users don't have to digitize all vertices of the 
common boundary (quoted from a previous thread on this topic)."

Podes ver no manual do QGIS 1.7:
