How to convert Autocad lines to Esri polygon shapefiles using FME?

Question

I am using FME to transform a dwg file into a polygon shapefile (.shp).

The dwg file is an urban plan of a city consisting of building blocks (type: polylines) and the properties within each block (type : line).

I used the GeometryCoercer transformer to convert type:line to type:polygon but it does not seem to work. I have also tried AreaBuilder, no success.

For those familiar with the FME software can you suggest Any solutions?

UPDATE

I attach an image of the dwg file (INPUT)

green closed polylines represent building blocks orange lines represent properties

I used the workspace as provided by @Mapperz, but it didnt work out. I set the geometry coercer *type : fme_line* , then 2dForcer and AREA BUILDER writing to a .shp with attributed geometry *shape_polygon*. This is what I get.

When I set the output .shp geometry to *shape_polyline* I get the following

I need a shapefile where all buildings and all properties will have a polygon geometry in order to add attributes to each polygon.

Answer 1

Using FME 2013 beta here

read the CAD [DXF] control the geometry - GeometryCoercer (FMEline) control the geometry - Force 2D (2d line only)

Build the Polygons

Output port AREA

Write Shapefile

See Image - as proof of concept.

Answer 2

with autocad map this can be accomplished fairly easily.
Perhaps the first thing you should do is to close the polylines that may give you a better polygon result.
