I am trying to visualize lithology data in ArcGlobe, i.e, the representation of different types of soil data under the earth. This I have done properly by creating Z aware featureclass and extrusion properties. I have attached a picture, a representation in Globe. In this diagram each color in the 3D bars is one feature representing the type of soil. Here I want to show the labels from the attribute table having the depth information of each feature. But when I am applying extrusion automatically, the Show Labels menu gets disabled. Is there any way to add labels programmatically (vertically next to each feature) like 3D text elements etc?
