CAD or Doc files Association with WT part

Hi all,

I have a small question to reduce the manual work.  I have given a work to change the association of WT parts from doc files to CAD files.  I have 100's of files to associate.

In the progress of work, I need to associate all the CAD files and change the association type of each individual, later I need to delete the related document object.  As there are 100's of file, I am taking more than 05 to 10 days to complete the task.  But I don't want to waste my time working on it.

FYKI, I am using Windchill 10.2

Please provide some suggestions.

Thanks
