After a concrete column design, right-click on any designed concrete column and then select "Concrete Column Design Results" from the popup menu that appears. The scrollable results form shown below displays a useful summary of the design results for the column you selected.
While the form is open, you can simply click on any other columns to have their design results displayed.
To get a fully detailed concrete column design report, refer to "Output", "Creating and editing concrete columns" or "The concrete manager".
