In the NCVAR Geometric Variable dialog box, there is a button labeled Notes. This will allow you to read or input any notes you may have regarding the variable you wish to change. This can be helpful if you need to change an NCVAR to a specific value, and then change it back later. Entering the value, and the reason for the change will make it much easier to change back later. There will usually be notes in the box already.
Click on a blank line in the Information Editor box, then click on the input line just below the Current Edit Line, enter the text you wish to input, and then click on Insert. The line will be input.
If there is information you wish to delete, highlight it in the Information Editor box, then click on Delete. The information will be removed.
