In the ArcGis PRO scene, we display pipes (e.g. fire rescue system), both horizontal and rising. For horizontal lines, we fill in the values of the elevation and the height of the pipe in the attribute table. We display the line graphically. In the scene, the pipe display (it is actually a pipe) is then assigned to the view located at the appropriate height.
The rising pipe is displayed in 2D using a point.


In the attribute table we have the values of the altitude, the height of the lower edge of the pipe and the upper edge of the riser pipe. (abs_vyska (m), vyska_1(mm), vyska_2(mm))

In the scene, we extract a point using a circle of about 30 to 50 mm in size (here the diameter does not matter so much, we modify the pipe from 1 to 100 mm with a point and from a diameter of 100 mm with a polygon), which we place at the appropriate height and then perform a "point extrusion" with the difference between the upper and lower pipe heights. The result is a sufficient visualization of the vertical pipe for us, which is impressive and effective.


When displaying pipes in an ArcGIS online scene, horizontal pipes can be displayed similarly. This is possible in the online scene. But what is problematic, or rather, we cannot display in a similar way, is the riser pipe.
How do I extrude a point to have a nice, round pipe in the online scene?

I am desperately asking for an expert or advice.
Many thanks in advance.
