KNOW THE DURATION OF TIME WORKING IN AUTOCAD

Here is a trick to know the statistics of an image on whatever version of AutoCAD. Higher versions can open the file version is lower, lower version can not open files of higher version. (I use version 2007). The goal of knowing how long a person complete a picture
Open the program AutoCad point the mouse pointer to the file and then click again and the pointer to point and click drawing properties (Figure 1)
(figure 1)

In the drawing properties window pointer to point and click taabulasi statistics (Figure 2). There can be seen the length of time of processing an image.
(figure 2)

So hopefully useful.
