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.
Depending on the frequency of updates you can either establish a standard frequency update (say once a month/week/day file> batch deploy), or monitor the data in case of a high frequency update cycle.

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.
