CII made many giant steps forward in the eighties. It also made a giant step backwards in not being able to add comments. 25 years ago you could add comments to text based input.

Following an old calc is virtually impossible. Was that restraint assumed to be a hanger rod or did I forget to add friction ? If you can't understand what you or anybody else did 3 months ago, the calc is worthless.

The "excuse" for not including a comment field was that nobody would agree on its length. I would want about 40-50 Chars. Enough for "Dimension estimated", "Guide support assumed", "Trial dimension". Any longer notes could be covered by a cross reference "See Note 1" etc.

Ok, it is possible to add comments to the title sheet. This is labour of love because you have to move to the front sheet, find a place to make the note, cross refer you comment to the element and then get back to the element you started from. A week later you merge the calc and renumber nodes. Your comments are now ratsh*t.

Any insurer or public body inspector doing serious QA on calcs as opposed to simply checking signatures should demand full annotation and comments of every calculation.
