Dear Yanhua,
Thank you for contacting SolidWorks Technical Support.
As we talked on the phone, currently there is no direct way to move origin and workaround can be moving body feature or inserting this part into a new part as reference file.
Enhancement requests are handled by the Product Definition team and should be submitted directly to them via the following form on the SolidWorks web site:
