Univalent Singular Files Vs. Duplicates : Why is it so CRUCIAL?

In the world of CAD, Unique files are a must. It’s so important, yet it is not clear to everyone.

We are all using XREFs for many years, some times we are prompted to reload during an AutoCAD Session, sometimes the XREFs will reflect their being updated when we open a file that has another file attached to it.

Univalent Singular Files Vs. Duplicates : Danger!

What if you discover you are not working on the right file? What if you use somebody else’s design as a background and change your design according to his/her’s and then discover the real file (the one the other designer is working on) is not the one attached to your file?

The Most tricky (I consider it a crime against humanity) will be that the Name and or the Path have been modified irresponsibly so The pointer keeps pointing to the right name but in fact the file has been replaced.

Other Problems are caused by different types of Attachments &/or Overlays and different kinds of PATHS (Relative, Absolute, No Path) and finally AutoCAD (Being a network program) offers different kinds of Demand Load methods.

Univalent Singular Files Vs. Duplicates : Is there a solution?!??

There is no AutoCAD Built-In Solution but You might want to create a unique ID so the XREFs are recognized without changing the names….The solution might be manual or automatic according to your capabilities.

Univalent Singular Files
There are billion of roses in the universe but the little prince’s rose is definitely unique

The 1st thing I would recommend is to use the DWG (File) Properties to attach this Unique ID. Then it might be attached as a field to an attribute which can be extracted from a bunch of drawings on demand. Of course I think about much more efficient ways and much more reliable, using automation to avoid human error feasibility, which was adopted as my approach from the very beginning of My World of CAD.
