RESOLVED * How to do this the most efficient way

[mvrp350]

Hi,

What I have is a list with x,y,z coordinates (I.e. x1,y1,z1,x2,y2,z2,x3,y3,z3,x4,y4,z4.. etc)

I split the list, and put the X, Y, Z coordinates in three seperate arrays: arListX, arListY, arListZ.

The problem is that some coordinates have more then one occurence in the list with coordinates. (x1,y1,z1) = (x3,y3,z3)

What I need to do is to filter out all the double occurences in my list.
And after that I need to have the list sorted.
The sorting has to be done in the order x,y,z

x1 = 50 y1 = 12 z1 = 25
x2 = 75 y2 = 12 z2 = 25
x3 = 50 y3 = 10 z3 = 25
x4 = 60 y4 = 12 z4 = 37
x5 = 30 y5 = 10 z5 = 37
x6 = 60 y6 = 10 z6 = 37
x7 = 60 y7 = 10 z7 = 25
x8 = 60 y8 = 12 z8 = 25


this should become:
x1 = 30 y1 = 10 z1 = 37
x2 = 50 y2 = 12 z2 = 25
x3 = 60 y3 = 10 z3 = 25
x4 = 60 y4 = 10 z4 = 37
x5 = 60 y5 = 12 z5 = 25
x6 = 60 y6 = 12 z6 = 37
x7 = 75 y7 = 12 z7 = 25

Thanks anyway,
