Hello everybody! I need help  Is there a way to import colour along with point coordinates? For example, I have points defined in .txt format in three columns, after which I have three columns that contain RGB colour components: X Y Z R G B 100 200 300 51 153 204 So I would like to import this point in this colour into AutoCAD. Is there a way to do that? |

You'd have to use a script or some code (lisp, etc.)
For example a lisp routine could read the file, one line at a time. the first 3 items in a line would be combined to for a 3d point. The next 3 values combined to form "r,g,b".
The coordinate would be fed to a "point" command.then "change" or "chprop" command, "color" then the RGB value.
Repeat for each line in the text file.
Script would be tedious. You might first manipulate in Excel to combine the values.
A script file would look like;
point
x1,y1,z1
change
l
p
c
r1,g1,b1
point
x2,y2,z2
etc...on and on for all points
