 How to reduce number of triangles in existing terrain model? I can not import point cloud again. 
 Is there an option to filter triangles after the slope to merge triangles with similar slope?</description><dc:language>en-US</dc:language><generator>Telligent Community 12</generator><item><title>RE: How to reduce number of triangles in terrain model on openroads?</title><link>https://communities.bentley.com/thread/776956?ContentTypeID=1</link><pubDate>Wed, 09 Aug 2023 05:17:55 GMT</pubDate><guid isPermaLink="false">6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:08b66f74-4017-41d5-97cf-f343426c75da</guid><dc:creator>Marek Demczyna</dc:creator><description>&lt;p&gt;Thank you for your advice.&lt;/p&gt;

&lt;p&gt;Actually, if you&amp;#39;re working with Point Clouds using a large dataset, you can reduce the density of the POD to as little as 2% and create the terrain from that reduction.&amp;nbsp; Additionally, you can export that reduced POD file, then&amp;nbsp;remove the original and reimport the reduced POD version allowing you to refine it down further from 100% of the reduced density.&amp;nbsp;&amp;nbsp;&lt;/p&gt;

&lt;p&gt;I&amp;#39;m not aware of such a process in ORD.&amp;nbsp;&amp;nbsp;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
