Thanks.. yes, I saw your PDF export feature, it's very nice.. but what I mentioned is a little different, for example, when we create a project, this 45-inch kadi can be 5-10 meters long.. after finishing this project, saving it with a different saving format.. during this recording The pen thicknesses that we set in the original file should not be corrupted and it would be better to set an unlocking password if desired. We should be able to open the file we saved as in the WREP program and get a printout. It will be enough for the Control Only person to have the ability to add comments to the places they see wrong, as in the "Adobe Reader X" program. that is, after the person who made the project makes a different recording from his original file, another person will not be able to make any changes on the project, so a drawn plan can be sent to the necessary institutions for control over the internet without fear of using it by someone else. "The WREP program is very suitable for this, it can be done easily with a little modification." Thank you for your interest.
