When only observer points are provided, the horizon line is generated by casting a line of sight from the observer covering the azimuth range specified in the azimuth options.&nbsp; The default azimuth options are 0-360 with increments of 1 degree.</SPAN><BR /><BR /><SPAN>Best,</SPAN><BR /><SPAN>Eric</SPAN></BODY></HTML> Thu, 15 Nov 2012 16:32:42 GMT https://community.esri.com/t5/3d-questions/how-to-create-horizon-view/m-p/336696#M2051 EricRice 2012-11-15T16:32:42Z Re: How to create horizon view? https://community.esri.com/t5/3d-questions/how-to-create-horizon-view/m-p/336697#M2052 <HTML><HEAD></HEAD><BODY><BLOCKQUOTE class="jive-quote">Greetings,<BR />The <A href="http://resources.arcgis.com/en/help/main/10.1/index.html#/Skyline/00q900000056000000/">Skyline</A> tool is what you want to use.<BR /></BLOCKQUOTE><BR /><SPAN>Thanks, Eric.
