algorithmic modeling for Rhino
hi all,
i try to setup an expression like this: (Attach File)
if a < 500 then b, and if a between 500 and 600 then c, and if a>600 then d .
but i don't know the syntax which can handle this.
hope you can help me.
thx.

If(A < 500, b, If(A > 600, d, c))
It's not very clean, but for a three-way split it's not too bad. This expression works as follows:
If(A < 500, b, If(A > 600, d, c))
If A is larger than 600, then the result of the bold part is equal to d, otherwise the result is equal to c. Let's call this result c|d, meaning it's either c or d, depending on the value of A. We can now rewrite the original expression and simplify it:
If(A < 500, b, c|d)
This is just a single If...Then construction where the Then part is the already partially solved result.

In the original post, "if a between 500 and 600 then c", I can't decide if that should be taken as 'inclusive', ie. 500<=a<=600, or 'exclusive', ie. 500<a<600, of the end points. I'm tending to think it generally means exclusive but the more I think about the less clear it becomes.

thx,
that works fine :)
@chris: thx for the definition, i will try it also.
