If the options 2 or 3 are selected on the first page of the interface the calculation does not check the capacity of the column for any applied loading.

Solution

This is intentional. To check the capacity for the applied loading the 'Check capacity of a column for specified loading' box on the first page of the interface should be checked in which case the interaction diagrams are not created.The reason the calculation is set up like this is that to either produce the interaction diagrams or check a column for the specified loading requires iteration which can be a lengthy process however to determine the the actual design moments is very quick as this doesn't require iteration. Therefore if the user obtains the interaction diagrams they can quickly check many identical columns (same size and reinforcement) for several loadcases by plotting the design loads on the interaction diagrams. To run the same information through the capacity check route would take much longer.
