Extruding Polygons to look like trees in ArcScene

I am pretty sure that I've seen this before.. but can't remember where. How do I symbolize my tree polygons as extruded, somewhat realistic looking trees?

Mapping Center Answer:

Extruding, at least the geoprocessing tool, won't make a tree. 

What you really need is a 3D symbol for a 3D point feature that represents the location of your tree.  You can import .3ds (3d Studio), .flt (Open Flight), .skp (SketchUp), and .wrl  (VRML)files when creating a new Marker symbol of Type "3D Symbol".

Another way, if you don't have a 3D model of a tree available in any of the above formats, you can make a 2D tree by making a 3D Character Marker Symbol that uses the glyphs in the ESRI US Forestry 2 font that was installed with ArcGIS.  Just pick the tree silhouette you want and set the properties.
