Hello, Columns have local axes of their cats, independent of the global axes. Rotating the column while drawing also changes the direction of the column axes. If the "Draw column axes" option is checked in the general settings, an arrow is drawn at the column joint point. The direction the arrow points is the +X direction. Accordingly, the set of axes is determined, and the Y axis is the direction perpendicular to it. The values you enter in the Offset X or Y box may cause the column to shift in different axes in the global axis relative to the local axis set. Good work.
