Finding top 3 values

What version of PC-DMIS are you using? This is possible with Constructed Extreme Point

2020 R2

Try the code above for right now, I'm working on something. When arrays get too long you can't fit them together. And I forgot how to get 3 arrays to be considered as individual values. Here's the shorter version. Change your statements to whatever your feature name is.

ASSIGN/V1=ARRAY(SQRT((1CR1.HIT[1].X^2)+(1CR1.HIT[1].Z^2)),SQRT((1CR1.HIT[2].X^2)+(1CR1.HIT[2].Z^2)),SQRT((1CR1.HIT[3].X^2)+(1CR1.HIT[3].Z^2)),SQRT((1CR1.HIT[4].X^2)+(1CR1.HIT[4].Z^2)))
ASSIGN/V2=ARRAY(SQRT((1CR1.HIT[5].X^2)+(1CR1.HIT[5].Z^2)),SQRT((1CR1.HIT[6].X^2)+(1CR1.HIT[6].Z^2)),SQRT((1CR1.HIT[7].X^2)+(1CR1.HIT[7].Z^2)),SQRT((1CR1.HIT[8].X^2)+(1CR1.HIT[8].Z^2)))
ASSIGN/V3=MAXINDICES(ARRAY(V1[1], V1[2], V1[3], V1[4], V2[1], V2[2], V2[3], V2[4]))
ASSIGN/V4=SORTDOWN(ARRAY(V1[1], V1[2], V1[3], V1[4], V2[1], V2[2], V2[3], V2[4]))

SORTDOWN tells you their exact Polar Radius so you can verify that their values are for certain the highest

gablega Let me know if you need more help. I only did 8 hits because character limits, and didn't wanna add an extra variable for an example.

I have 2023 installed on my desktop as an offline version just to see if it's worth transitioning all of our machines to. Have never used extreme point though.

If you don't have thousands of points you can use a commonly known function called 'bubble sort'; inefficient but easy to setup. Much better would be 'quickSort' but I have no idea how hard it would be to program in PCDMIS... Otherwise I'd give you the functions lol. Easy to look up tho.
