The video starts by explaining the preference for working in 2D (XZ portal view) to avoid errors during the modeling of the ancillary columns. The user selects the XZ view and deactivates other elements to focus on the columns.
The next step involves drawing the ancillary columns using a specific bar type (UNP 200). Simple supports are then added at the base of these columns. The presenter corrects an oversight, ensuring all three columns, including the central one, have simple supports.
To ensure proper structural behavior against wind pressure, the orientation of the columns needs to be adjusted. The presenter re-draws one column to match the orientation of the others. The explanation highlights that the strongest inertia should be perpendicular to the wind direction. This requires changing the gamma angle of the selected bars to 90 degrees in the bar manager, ensuring the Z-axis faces outward.
Finally, the three modeled and correctly oriented ancillary columns are selected. A vertical mirror operation is performed using the XZ plan and mirror option to create the corresponding columns for the other side of the gable, maintaining the correct outward orientation.
