Question
CAD(polyline) to GIS(polygon) conversion
I have CAD floorplans (DWG) as polylines and I want to convert them into individual room polygons with the appripriate attributes (room number, size, etc.) to be used in ArcGIS (shapefiles or geodatabase feature classes). If possible I would like to have automated updates for when an AutoCAD file is updated. Is this possible? How would I go about setting something like this up? Thanks.

Hi,
I would try the following assuming the lines are topologically correct and have a common id per polygon:
- Use the area builder with a group by (polygon id) (any topology inconsistencies will fail)
- Set the polygon list name to gather all features attributes
- Manipulate attributes/lists to desired configuration.
- Writting the data.

Once DWG to SHP or GDB conversion is set up, u can use windows scheduler in batchfile. (http://ss64.com/nt/at.html)
In wich u can set up an changedetect in fme or tru filechangedetect cmd/database.
If u load em in a databes u can ofcourse use the appropirate scheduler instead.
