Hello,
I am trying to import a DEM into SU Pro 2015 (MacBook Pro, OS Yosemite) and am having difficulties. I downloaded elevation data from web-site (search for "Mntopo' web site) in the form of a DEM. The resulting files were of extensions .bil, .hdr, .xml,.....I had no luck importing. I tried downloading from the same web site in a different format , the extensions were different (and many). Still, I had no luck importing. Any suggestions? I am trying to create a 3D model of a wetland mitigation site. Thank you! Best, Jeff
