To create the concrete column member, double-click the vertical line in the center (no. 9).
Select the Member option. The 'New Member' dialog box opens. The CIRCLE_M1 12 section is preset, which is appropriate.
Click OK twice to close the two dialog boxes.

Nonetheless, the results are sufficiently accurate. The design of the circular member is demonstrated in Part 2 of the tutorial.
