File Already Exists Error
If you receive the above message while trying to save your drawing, it means that you don't have enough privileges to save to the Drive/Folder where your EFD file is stored.
You can fix this in 2 ways:
Get your IT dept. to change the privileges of the folder so you are able to move, edit and delete files (recommended).
Save the drawing to another location where you are not restricted, such as your local hard drive.
