topic Sampling a 3D building and performing intervisibility analysis in 3D Mapping Questions https://community.esri.com/t5/3d-mapping-questions/sampling-a-3d-building-and-performing/m-p/874789#M966 <HTML><HEAD></HEAD><BODY><P>The attached figure is a snapshot of the ESRI 3D Urban Analysis. The yellow dots around the right building are the sampling points of the 3D building. I tried many ways, but failed to reproduce it. Could anyone tell me how to do it? Also, the left buildings are demonstrated as stacked grid cells and the graded color representing the degree of visibility. I very much like to do it, but I have no idea on how. Could&nbsp; anyone provide some clues?&nbsp; --- thanks</P></BODY></HTML> Thu, 05 May 2016 10:41:58 GMT PengGao3 2016-05-05T10:41:58Z Sampling a 3D building and performing intervisibility analysis https://community.esri.com/t5/3d-mapping-questions/sampling-a-3d-building-and-performing/m-p/874789#M966 <HTML><HEAD></HEAD><BODY><P>The attached figure is a snapshot of the ESRI 3D Urban Analysis.
