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,
David

Hello
I’m using QGIS 3.12
I have a poly shapefile named building.shp in the zip file, and a line
shapefile, named line.shp.
I’m using the geoprocessing function ‘split polygon by line’ using
poly.shp as input, and line.shp as divide layer.
I obtain the ‘split_by_line.shp’. But, in this splitted file, the
polygon was not divided considering all the lines present, but only
some of them, as visible in ‘split_by_line.shp’.
Is there something wrong?
Regards
