The unbraced length is automatically determined from the column length specified by the user and the bracing status for the column line determined by the program or specified by the user. It also accounts for any changes made to the column height from sloping framing created by the user with the Layout – Columns – Modify Elevation command, the Layout – Foundations – Spread – Modify Elevation command, or the Layout – Foundations – Continuous – Modify Elevation command in the Modeler. The unbraced length is the sum of the column lengths between braced levels and it is determined independently for the X axis and Y axis.
