New Vision Algorithm

In reference to the above, I'm looking to start trying to make a hopefully temporary 'work-in' for this. Does any one know if there is a way to calculate T-Value of individual points of a Line? I want to index them into an array.

Any help is appreciated.

Perhaps this? Can't test ATM.

(dot(array(lin1.hit(1..lin1.numhits).xyz-lin1.txyz),lin1.tijk)

I then need to figure out how to re-associate that with the point index, then filter out the indexs accordingly.

Here it's not the dot product to use like this.
You seach the distance to the line, so it's a double cross product.
ASSIGN/V1=CROSS(CROSS(LIN1.HIT[1..LIN1.NUMHITS].XYZ-LIN1.SXYZ,LIN1.IJK),LIN1.IJK)
ASSIGN/T_VAL=DOT((LIN1.HIT[1..LIN1.NUMHITS].XYZ-LIN1.SXYZ),V1)

I'm not at the cmm to check, so I use SXYZ to use start point instead of centroid.
I do it because the result of the cross product could change of direction from a side to another of the centroid.

This should help :
ASSIGN/V1=CROSS(CROSS(LIN1.HIT[1..LIN1.NUMHITS].XYZ-LIN1.SXYZ,LIN1.IJK),LIN1.IJK)
ASSIGN/T_VAL=DOT((LIN1.HIT[1..LIN1.NUMHITS].XYZ-LIN1.SXYZ),V1)
