Finding the sum of split.index

maziaryousefi

Hello everyone. Is there a way to get the sum of the numbers generated by the division command using split.index? For example, we have a 5-story building and if we use the split.index command, the floors start from zero and finally the 5th floor receives the number 4 and the sum is 10, that is, 0+1+2+3+4 = 10

I'm curious whether your goal is simply to compute the sum of split.index values,
or if you also want to pass that sum into other rules for further use.

If your goal is just to calculate the sum, you can use the formula  "(split.total - 1) * split.total / 2"

If you'd like to pass the calculated value to other rules and use it there, you can write it like this:

attr unitHeight = 2   // Height of each split section

@StartRule
Lot -->
    extrude(10)  // Give height to the lot
    split(y){ ~unitHeight : Section }*  // Split along Y into equal parts


// Use 'with' to define sum_n as the sum of split.index values
Section 
    with ( sum_n := (split.total - 1) * split.total / 2 ) 
-->
    case split.index == 0 :
        Something_A(sum_n)
    ..
    ...
    ....
    else :
        Something_Else(sum_n)

 There may be various ways to approach this, so please take this as a reference only.
