OpenSCAD is not good for I/O. The way you probably want to handle this is by using a script to convert the file into an OpenSCAD library that reads something like: Mydata = [ [1, 1, 1] 10, 1, 25] 1, 2, 3] 5, 2, 3] ... ]; Then use "include" or "use" in your OpenSCAD file to pull in the data. There are various tools you can use to do the conversion or you can do it with a reasonably powerful text editor. I favour sed <https://www.gnu.org/software/sed/manual/sed.html> myself, but it does have a learning curve. -- View this message in context: http://forum.openscad.org/Import-data-in-a-txt-file-tp18914p18915.html Sent from the OpenSCAD mailing list archive at Nabble.com.
