I actually found a solution and wanted to post it for future reference.
Let’s say we have a CR1 Feature containing 10 points.
We then declare 3 real values called rl_x, rl_y and rl_z.
we can obtain the first point by typing this :
rl_x = OBTAIN/FA(CR1)[1],2
rl_y = OBTAIN/FA(CR1)[1],3
rl_z = OBTAIN/FA(CR1)[1],4
The syntax to obtain a feature’s actual values would go like this :
var = OBTAIN/FA(chFeatureName)[n] ,rlValueIndex
Where n is the point index of the feature’s individual point data.
