Terrain from Borehole Lithology which has multiple samples of the same materialhttps://communities.bentley.com/products/geotechnical1/f/geotechnical-forum/158207/terrain-from-borehole-lithology-which-has-multiple-samples-of-the-same-materialI&#39;m trying to create a terrain using borehole lithology. The borehole data is quite detailed and in many instances contains multiple layers of the same material (albeit with different notes etc). When I create a terrain it doesn&#39;t select the top layeren-USTelligent Community 12RE: Terrain from Borehole Lithology which has multiple samples of the same materialhttps://communities.bentley.com/thread/471938?ContentTypeID=1Fri, 20 Jul 2018 17:28:20 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:4a09baf1-4d53-42c9-b086-b13f4f3f0ad1Kirk Johnson<p>Ok Great will look into. If I find an issue I will create a service ticket and we will handle at the development level.

Send me the project file you are using and I will try it.</p><div style="clear:both;"></div>
