Question

Are there any 'magical' attributes to check Autocad features version?

We keep data in commercial geodatabase but need to communicate with subcontractor via Autocad format. Subcontractor makes some changes in original file. Is it possible to handle in FME only changes in efficient way? Are there any smart way to get which features were changed/added? Any native (Autocad) flag to store feature version or else good practice? We don't want to make geometry matching with original and revised data.

I usually like to use the crc change detection method for this, you do however need a common id for it to be used.

Thanks @itay. I know crc change method. So what is the good practice to store source geodatabase ids in autocad files? Extended entity data or keep additional table on the side with e.g. ids and autocad_entitiy_handle values or something else?

my preference would be to store the data on the Autocad file, to minimize that dependencies on external files.
