When using 'Publish selected layouts' or doing a batch plot in AutoCAD 2024, the riser nipple/vertial pipe does not display correctly.  It'll either be missing outright or a proxy bounding box will be in its place.  If you plot a single sheet, it works fine.

When plotting two viewports, one with center-to-center lengths, and the other with cut lenghts, the riser nipples/vertical pipes will show both, even if your layout tab looks fine.

User created two viewports in a layout tab of a 3D pipe drawn in the 3d_details layer.  One of the viewports plotted fine but the other didn't show the pipe at all.

possible annotative scale issue.

bad head definition, in this case Head4

When attempting to insert a pipe dimension you get the error "Invalid option keyword"

And the command prompt says "Enter an UNDO control option" with the dialog showing your choices

When attempting to insert a cap, it draws the pipe and dimensions it, but it doesn't insert a cap.

However if you draw a test pipe elsewhere, it successfully inserts the cap for you
