Works for my:
From this thread (10 months old):
http://forum.librecad.org/LibreCAD-for-mapping-td4549798.htmlFile->Import->Read ascii points
Simply change "format" to "Comma separator" for CSV files
The format of the data expected by the plugin are (code not mandatory):
number,x-coordinate,y-coordinate,z-coordinate,code
like:
1,257.65,354.25,0.0,wall
2,293.58,355.98,0.0
3,315.12,357.37,door
The "format" is the most important, if you select "Comma separator" and the file
is "space separator" the plugin do not work.
