I have a task to upload survey areas contours for different years from dwg into polygon shape format. And I am using FME for automatic transformation of data into gdb. Sometimes my .dwg contain unnecessary data and my idea is to leave only those parts of dwg that has the majority of objects in it (let's say it's ok if I neglect 10% of data as I need just outlines of survey areas). To be more clear, I attach a picture of original data in dwg and purple margin of what I want to receive as output. Any ideas how I can achieve that? I have a few thoughts, please share your views on that, thanks a lot in advance. kkt
