      The earlier one was Deep exploration, the above was Vue, I simply imported the dxf and painted terrain by elevation. No need to reduce as Vue can handle billions of poly's without glitch. However I can reduce in Vue and export to SU if needed.

      I have Deep Exploration and have tried to replicate the reduction results you achieved earlier but without success. Can you tell me how you did it?

        Sure.

        Open dxf in SU, then save as SU6 version.
        Open it up in DE, and select reduce, process and select 90 percent. Then select heal and save as SU model.

        That's all.

          Oh, I see. So you were only removing 10% of the triangles. No wonder I was having issues, I was clicking 10%, thus removing 90% of the triangles.

            No, remove 90 percent. see file size from 35MB to 2.6MB

              Then there is hope for it still. I am doing the same, or so I thought, but the results are not like yours. I wonder what it could be? My version comes out with strange patches or blotches all over it..

                Other filtering approaches using MeshLab again but this time doing Vertex Clustering Decimation. SU edges 25625,16900 faces and file size 2599K. The filters it includes are some developers have incorporated in their apps. .Vertex Clustering Decimation.jpg[/attachment]
                IMO trying to take this model and editing is not the way to go based on the goal of your OP. To create a virtual tour you must get to the point of selective editing only portions of the map along the lines bjornkn discusses This can be in the decimation or interpolation sense โ“
                Next step, layers and selective edits?

                  Those results look quite promising and seem to retain much of the fine detail.

                  I completely agree about only editing certain portions along the line. Given the sample I uploaded, a true sense of perspective is lost. Here is a set of 3 meter contours for the entire area involved. I would upload the full resolution version but the file size exceeds the attachment limits. The small patch I uploaded is located near the lower portion of the midpoint. See attachment:

                    Got that in a DEM file? or even .obj, dxf.

                      Yes. I am actually using a DEM file as the source for the sample DXF I uploaded.

                        If you can upload it, or part of it, I'd like to try something with Terragen.

                          I tried uploading it earlier and it was rejected because the file was too large.

                                  I'll go create an account now. What format do you prefer the data to be in? I am currently extracting it to a DXF mesh, is that ok?

                                      The DXF mesh extract was huge and is still uploading to my dropbox but the DEM extract was surprisingly small. See attached:

                                        You may want to check the dem file, it's kinda wierd, hard to explain, lacks all detail.

                                          I looked at it and see what you mean. I must have inadvertently selected the wrong scale when I exported it. The DXF file just finished uploading, here is the link:
