Self Intersection PolyLine To Multi Region
« on: April 06, 2016, 05:32:43 AM »
Hi everybody,
Here I've meet a problem which is below
the image is attached below
In my situation, I have a  self-intersecting PolyLine(I User two in example and may have more in usage)
And I tried to explode the polyline and I get a DBObjectCollection and the count of the dbobjectcollection is 8.
So I wanna Know how I can get the total region of the polyline(in the sample ,I wanna get the 2 region in both 1 and 2
and also How can I get two new poly line use the dbobjectcollection)?

Wish to get help from you!

Hi,

You cannot create regions from self intersecting polylines.
If you explode the polyline into lines, you have to "cut" each intersecting line at intersection point, then you should be able to create regions from the lines.
