There is a tool for DEM to Raster in ArcGIS but I need to convert my ArcGIS DEM rasters (mostly LiDAR) into USGS DEM. The idea is to import this DEM into Sketchup and create a "sandbox" TIN surface and for this SketchUp needs the data to be in this particular format.
In the past I mostly used the Sketchup Plugin to export TIN from ArcGIS to Sketchup which worked great but since the plugin no longer works in version 10. I am trying to create a new workflow but I am not having much success. The "Collada method" does not work well for complex surfaces. It requires to first create a multipatch and there is the first issue as described here. Besides, it is painfully slow if the conversion even succeeds at all.
