It sounds like the structural column is not being displayed due to its positioning relative to the cut plane and top plane in your view. Here are a few suggestions to address this issue:
1. Adjust the Cut Plane: If moving the cut plane up shows the column but doesn't work for your view, try adjusting the cut plane in a way that allows the column to be visible without compromising your desired view too much. You might need to experiment with different cut plane positions.
2. Visibility Settings: Check the visibility settings for the structural column. Make sure that it is set to be visible in the view you are working with. Sometimes elements can be hidden or set to be invisible in specific views.
3. Override Graphics: If the visibility settings are correct, you can try overriding the graphics of the structural column in the view. Select the column, right-click, and choose "Override Graphics in View" to manually set its visibility.
4. View Range: Ensure that the view range settings, particularly the "Cut Plane" and "Top" values, are appropriately set to include the structural column. Adjusting these values might make the column visible in your view.
5. Element Positioning: Check if the structural column is correctly positioned in the model. Sometimes, elements may not appear in a view if they are placed slightly outside the view's boundaries or if they are not aligned with the view's plane.
6. View Discipline: Verify that the view discipline (e.g., architectural, structural) is set correctly for the view. Certain disciplines may hide or display elements differently based on their category.
If none of these suggestions work, there may be a more specific issue with your model or view settings that requires further investigation.
