You can change the information about fields in the Groups Tables in the Library Window. To change the name of the field, click on its current name, type in a new name and press the enter key.
The units for the field may also be modified. In the units column, type in the name of the units you want to use to store properties in this field. For example, if you added a field named Iw for a warping constant your units might be in^6 (inches to the sixth power) so you should type this into the units column. You should also type in a factor to convert the fields values into Section Maker's internal units system. This will allow you or another user to change units and still have the properties displayed correctly. The factor is the number the entered value must be multiplied by to convert it into a Newton, meter, kilogram units system. i.e. in the case where Iw will be entered in units of in^6, the factor will be 6.820907E-12 (i.e. 1/39.37 to the power of six as there are 39.37 inches in a meter)
