topic LAS Dataset to TIN Failed in ArcGIS Pro in 3D Questions https://community.esri.com/t5/3d-questions/las-dataset-to-tin-failed-in-arcgis-pro/m-p/376140#M2257 <HTML><HEAD></HEAD><BODY><P>I have been trying this operation for several days now and have look through some of the GeoNet answers, but I still can't get it to work. Basically, I have a LAS Dataset from a UAS which was processed and exported from DroneDeploy. I want to create a raster or TIN from the LAS Dataset. I can create the TIN if I set the Thinning Value to 7900, but if I use any value above that, I just get a generic Error 999999 message.&nbsp; Below is the result window.
