Revit 2021 - W Shapes-Column Family is Missing

The stock imperial architecture template has the W Shapes-Column family loaded with two types: W10X33 and W10X49. I was experimenting with new features and noticed the family isn't part of the 2021 content deployment, weird. I had to reload from the 2020 version to add a size.


If it's not one thing it's another.

Structural Column Disappears in Detail View Type

When we create a Callout within a plan view we can choose between Floor plan and Detail. A structural column that uses a negative offset won't show up when a wall exists in the same location when a Detail view type is used. It works fine in a Floor plan view type.

Here are some example images. The first one is showing the negative offset used. If the offset is zero then there is no graphical issue, the column shows up.


This image shows both callouts in the overall floor plan, Detail on the left and Floor on the right.


This is the Floor Plan Callout, column shows up as expected.


This is the Detail Callout, no column is visible.


This is the same Detail Callout but my cursor is hovering over the column and Revit sees it, highlights it despite not being visible. The wall is masking the column.


This is the same Detail Callout but the view is changed to use Wireframe and the column appears.


It boils down to the negative offset applied to the column. The graphics hierarchy does not respect the full height of the column and the wall element is drawn over the structural column. We can also get around the issue if we edit the column family and remove the option: Show family pre-cut in plan views.

Structural Plan View - Column Symbolic Offset

From the Dept. of Subtle we only find this parameter in Structural Plan views.


The help documentation says we can use this to "Specify the offset of a beam join to a slanted structural column. This only applies to coarse detail levels.". I've mocked up some framing to see what it does.


In this next image I've changed the offset value to 5'-0". You'll notice that the column symbol moved down toward the bottom of the column.


In this next image I've changed the offset value to -5'-0". You'll notice that the column symbol moved up toward the top of the column.


If a column doesn't pass beyond the view's level a negative value doesn't do anything to change that column's symbol location. Pretty subtle...
