@MarkRamos7211 AutoCAD never showed total length for different objects. If you have a single polyline, or you use the JOIN command to make them a single polyline you will get the length of that polyline. but if you select multiple objects you will get either the length value if all objects have exactly the same length, or the *Varies* value if some of the objects have a different length.
It is more likely you had some customization work done, or you had an app or plugin active that added that information to your properties palette.
You can use a lisp routine to get the total length of lines. The routine in attachment will let you pick multiple objects and give you an alert window with the total calculated length. The routine is not mine, I picked it up somewhere in these forums several years ago.
You can use the APPLOAD command to load it into your drawing, and once you have done so you can use the TLEN command to start.
