I think I've used QGIS to its limits and as far as I know ArcGIS don't have any tool different that might be of help for me. Since I've heard about it a a lot yet never used it, I thought FME might have more options to do what I need. If I can do what I've got in my mind I am going to purchase the required license.
Basically I've got a very large and complex polygon road network and my main target is to divide those polygons into smaller polygons with almost equal lengths. Also divide them vertically with a centreline if the width of the polygon is above a certain length. But complexity makes things really difficult.
In two separate questions, more details on this issue are available on gis stackexchange.
