It is common practice to store parcel data as features in a central database while new subdivisions are created in a DWG file, using AutoCAD, AutoCAD Map 3D, or AutoCAD Civil 3D. What is the best way to handle this kind of workflow?
This method uses only two formats: SDF and DWG, and only two programs: AutoCAD Map 3D and AutoCAD Civil 3D. (This is assuming that you have your parcel fabric stored in an SDF database. However, the process would be the same if the parcels were in Oracle or any other supported data store.) If you store your parcel data in DWG files, the effort involved to convert them to SDF is relatively trivial, using Export from DWG to SDF (see ).
The first step is to extract the parcel or parcels that you need to edit from the database, convert it to simple geometric objects, and save the objects as a DWG file. You can then give the DWG to the engineer who will create the subdivision design.
When the design is complete, the engineer saves the parcels for the subdivision as an SDF file. The SDF file may also contain other features such as pipes and road alignments. You can easily bring this data into AutoCAD Map 3D with a standard Data Connect operation. Because the data has retained its georeferencing information throughout the process, you can be sure that it will come in at exactly the right location.
