I’ve tried everything to create a 3D sketchup model from arcmap data. Every plugin, everything, I’m obviously missing something. The dataset is huge, several acres with severe topography. I'm not understanding how to get the end result of a DEM file. Once before I created a 3D terrain model in sketchup from going throughs everal steps of taking LAS dataset and eventually getting it to a collada file on arcmap, but I've lost my bookmark on how to do that and can't figure that out. Any help is appreciated!
