Winzip pro will unzip a gz/tar. Winzip un-gz's then un-tars in one shot, and spits out a bunch of .ddf files. The main one is xxxxCATD.ddf (xxxx is some number)gregb wrote:John, how did you un gz the DEM file? Could you explain it in detail. Thanks.

So will 7-zip. 7-zip is open source.

With 7-zip, I think you have to run it first on the .gz file, then it will spit out a .tar file. Run it on the .tar file and it will spit out a bunch of .ddf files. Accutrans will read the main .ddf file (xxxxCATD.ddf). From there you can export out of accutrans 3d into whatever file type floats your boat. I picked .obj because I know a few different programs like .objs. It will also export .stl files too.

--btw, 7-zip is really nice too.
