Joining polygons

Hi Luis,
With SBuilderX I can't join polygons with same properties and common side. Have I missed something?

Hello,

These are my INI settings

NameJoin=False
DirJoin=False
DisplayJoin=False

Polygons are joined if they have common points. If DisplayJoin is set to True, then 2 points are considered to be the "common" if they are closer then 3 display pixels. If DisplayJoin=False then 2 points are considered to be the same if their latitudes differ less than 1/255 times the latitude_of_the_edge_of_a_quad_LOD13 and if their longitudes differ less than ...( a very small number).

Regards,

Luis

Thanks for the explanation. I just change the INI settings and all was fine.
