Under which tab is the column family located when placing a column?

The column family is located under the Structural tab when placing a column in a Building Information Modeling (BIM) environment. This is because structural elements, such as columns, beams, and walls, are inherently part of the building's framework and load-bearing system. The Structural tab is specifically designed to house families and components related to the structural integrity and support of the building, enabling users to easily access and place necessary structural elements in their designs.

In contrast, the Architectural tab focuses on elements related to the overall aesthetics and functionalities of the building, such as walls, doors, and windows, rather than the structural components. The MEP tab is dedicated to mechanical, electrical, and plumbing systems, which serve different purposes within the building. The Site tab involves elements related to the site layout, grading, and other external factors. Therefore, the correct location for column families is firmly within the Structural tab, aligning with their role in structural design.
