Importing DEMS
-
Hello All,
I am using Sketchup Pro 2015 (MacBook Pro, OS Yosemite) and would like to import a DEM. I downloaded a DEM based on contours produced from LiDAR (from MNtopo website). First attempt download option was open-source and extensions were .bil, .xml, .hdr.......) I could not import. Second download attempt (same website) was an ESRI-based DEM with a bunch of different extensions. Still could not import. Any suggestions? I saw some advice that said to change the extension to .dem, but not sure which file I should apply this change to. Thank you in advance! Best, Jeff

OK - I now know the the process. Here it is:
- From web-based topographic server (MnTopo in my case), zoom in to subject area, download "Contours" (not DEM).
- Zipped file e-mailed to you containing shapeless. Open in ArcGIS and back save to AutoCAD 2010 or earlier.
- Open file in Auto CAD, create bounding box, and clean up stray contours. Save as a .dwg .
- Open .dwg in SU and save as .skp
- et voila!
Cheers, Jeff
