Hi Luigi,
I think you can proceed this way:
- using the "Polygons to lines" tool, convert your the polygon layer
(building.shp) to lines
- using the "Merge vector layers" tool, merge your line layer (line.shp) and
the layer generated by the previous step
- using the "Polygonize" tool, create a
Luigi,
I see the problem now, I would suggest:
1. Polygons to Lines (on the Buildings layer)
2. Merge vector Layers (lines-from-buildings, and line layer)
3. Polygonize (merged layer)
4. Join Attributes from Location (New polygons, building layer)
(Geometric predicate = within)

Luigi,
The lines must fully transect the polygon in order to split. The dotted
lines in the image are examples of such lines.
Hope this helps,
