Asunto: [Qgis-user] SPLIT POLYGONS INTO 3 PARTS (similar size) 

Dear List, 
please I would like to have any suggestion regarding this topic: I have several 
polygons (all different shapes and not regular geometry) and I need to split 
every single polygon into 3 parts of similar size. 
I have tried with Split polygons but it is working very well only with regular 
geometries (square, rectangle etc.) and so I can not use it in this case. 

Do you have any suggestions? 

THANK YOU, AZZURRA
