    Think I'll add links inside the spreadsheet to the 3 forums where I update the threads so people can find them.

    Hi Woodee,

    I posted in Emery's thread how to do it, I'll repeat below with some tweaks to that original post:

    1. open Blender
    2. download and install the CSV Mesh Importer add-on from here: https://sourceforge.net/projects/csv-me-importer/
    3. open the asc file for the area you want in notepad or similar.
    4. delete:
    “ncols 500nrows 500xllcorner650000yllcorner 306000cellsize 2 NODATA_value -9999” for example.
    5. save the file with it's current asc or txt extension.

    6. in blender go to the scene tab, click Metric and scroll down to the CSV Mesh Importer.
    7. Change to Point XY 2D table (matrix), comma and spaces ticked, create vertices and faces and set the cell size for X and Y to the resolution of the LiDAR file : 1 for 1m, 0.5 for 0.5m etc. Leave the Z scale at 1.
    8. choose your asc/text under File Path: and click IMPORT, and wait
    9. Once it has imported, select the object, press CONTROL & M, and then press Y and ENTER. It imports mirrored incorrectly so the above puts it right.
    10. And that’s it!

    If you import more than one tile, note that there should be a gap between them, 1m for 1m data etc.... (see image below).

    It's really simple and the results are great to see.
