Sometimes I am getting text files that contain only XYZ (easting, northing, and height) with 10-15GB size (points or polylines). If I need to interpolate that file or create fishnet, adjust Z value of data or etc. in ArcMap it stops or taking forever. My comp specs I7,32GB RAM, working on SSD, GeForce GTX 1080, 4.20GHZ.
Please, if you have any suggestions let me know, thank you for your attention.
