Use the Grid tool to place column grid lines in the building design. You can then add columns along the column grid lines. Grid lines are finite planes. You can drag their extents in elevation views so that they do not intersect level lines. This allows you to determine whether grid lines appear in each new plan view that you create for a project. See Datum Extents and Visibility and Visibility of Arc Grids in Views.
Grids can be straight lines, arcs or multi-segmented.
You can hide grid lines after you add them. For more information, see Hiding Elements in a View.
