Dear Experts.

When I reuse the drawing files, I replace the part and fix them.

However, center line problems occur most of the time. (current Solidworks ver. is 2021 sp3  Japanese JIS standard)

The problems are...

1. centerline disappear ,after the replacement

2. Automatic insert doesn’t work after the replacement. (it appears first ,but after the "ctrl + Q ", or saving, it disappears) 

3. Center line which is drown manually become too short after the replacement. (pls check the attached file)

Does anybody know how to fix this problem , pls advice me how to fix them. Thank you .

BRGDs.
