+10@pranneshgeo, you will need to try out the LineBuilder to first build lines from the points and then AreaBuilder transformer for making polygons. The AreaBuilder takes a set of topologically connected linework and creates topologically correct polygon features where the linework forms closed shapes.

Hi.
1. Select all lines (tester)
2. Linebuilder, grouped by Class (I'm assuming different colors are different objectclasses) If not, group them by color.
3 Use a Intersector or a LineOnLine Overlayer . (LineOnLineOverlayer has tolerance option, you might want that if the drawing is topologically not perfect).
If topology still not ok, use 1 snapper "endpoint" maode and (maybe) 1 snapper in "segment" mode.

5. Relate the points to area using a SpatialRElator where area contains point. This way you can transfer the point info to the area.
If you need example, post the (sample) data you display in the image.
