Yep, I'm using the process you linked to- all works fine there. I used the "Extrude points" function to represent the variability in biomass, using 'Base Height' Type. The only problem is in adding a Legend, in the Layout view. It is simply adding a small hollow vertical column icon for the extruded points. Here's a segment of a ArcMap 2D representation, with legend (in blue dashes) as a scaled bar. I'd love to recreate this legend type, but using 3d Extrusion. Thanks!
