hi guys who use PID in AP3D

As you konw,when we create a PID drawing,we we select a title block with format *.dwt
But sometimes when we have created some drawings using this title block,
we want to modify it.
But then system will prompt the attached info and can't save it.
So we can't update the old title block.
So any solution.

thanks

May be you could save it another location and use Windows Explorer to copy and overwrite the original file?
