Hello ,

I have multiple lines connecting to each other in shape file and each multiple lines has different id with increment 1 ,

as example :

multiple lines include id ‘s : 250 ,251 ,252,253 ,….

and different multiple lines include id ‘s : 4090,4091,4092,4093,….

I would like to combine the lines together that connecting to eachother and increment with one from others id

 

my target : to convert each multiple lines that looks like square to polygon and also the street lines to be together as seperate another polygon .

i am not sure how to achieve that,so i have thought that may be i combine id with increment 1 , i hope if someone has idea ,let me know please

@spiderman​ You can create polygons using an Intersector and AreaBuilder. The extra lines that don't form polygons will come out of the Incomplete port. How do you want to combine the street lines into another polygon?

Yes please ,

i would like to create polygon for any box or square that I have , some times that data has big square and inside it small square

so I need to create both of them separate polygon .

and for streets also ,it is important for me to create polygon for it .

i know ,it should be common line between every polygon and other but it is okey for me .

Thanks for help

Are you able to share some sample data and a screenshot of the polygons you'd like to create from it?

By default the AreaBuilder will create donuts and not drop the holes. So if you have nested polygons then it should great "donut holes". Then use a DonutHoleExtractor to separate the shells into overlapping polygons if that's what you're after.

Hi @spiderman​ A screenshot would help! :^) Without seeing your streets, I'd recommend trying the Snapper, AnchoredSnapper, LineExtender (maybe a Bufferer?) and an Intersector to create polygons from your remaining lines.
