I request Coade members to include the following in the Caesar-II software,

The Center of Gravity of the piping system shall be shown in the graphical or 3D plot. Since the CG values are only shown at the end of error checking, and it may be useful if it is shown in 3D graphical view.

Also, i request the Coade members to tell the procedure to open the Caesar-II 5.1 version file to 4.5 or 4.4 version file. Since i dont find any option to open the file.

Showing the CG on the graphics is a good idea, but too late for Version 5.20. We can work on that for next time.

As clearly stated in the Update/Distribution letter, for many years, input files are not downward compatible. This is due to new data and new capabilities added in each version. You can go up, but you can't go down.
