Does anyone know how do I create the "aoi_park" as mentioned in the tutorial? You can see the "aoi_park" I refer to at the beginning of below video. https://www.youtube.com/watch?v=H-pi7Eih-5I
I have not viewed the tutorial, but you could use 3D Analyst Tools >> Functional Surface >> Interpolate Shape to add z information from a surface. The default sampling distance is your raster cell size, or you could set it to 1/2 your cell size. As and aside, you can set an offset of 1 (or more) map units to bring your dataset above your other data.

Hi Jim, thanks a lot for your reply. I tried the method you suggested, it worked to convert the 2D AOI to 3D AOI. However, I'm confused with the resulted 3D AOI. It appears a little higher than DTM. When I turn on DTM and 3D buildings layers, it looks normal. However, when I turn on 3D AOI and 3D buildings, some short buildings disappear (hidden under 3D AOI). Would you know how possibly I can fix this? Thanks
