For those who are wondering, next steps (which will be shown in the 2nd Draft) for my spatial planning work are:1. To show in graphics / visualizations the shadow analysis of the buildings that I was doing when placing the buildings on the landscape.2. To place trees on the site and cast their shadows on the landscape.I need to do this in Sketchup, but have never used it before. Also, my model is currently in ArcScene (the GIS tool for doing 3D visualizations), so if anyone can help with importing GIS files into Sketchup, or with using Sketchup, I would be most grateful.Francesca
