'IF' 'THEN' statement question

Hey guys,I have a loop from lets say: i as int32 = 0 to 50. I am trying to make an IF THEN statement, where: IF i = even integer THEN it does something ELSE it does something else. However I cannot figure out the right syntax to write this statement. Does anyone know how to do this? Any help would be appreciated.Thanks.See More

CA Script help!

Hey guys,I am trying to write a script which produces an aggregation of boxes according to a random number that has been generated through a loop. I want the boxes that have not been generated in the first loop to be generated in the second loop, or third..(depending on how many iterations I give it.) However, for each loop my script has been giving me a new set of boxes, instead filling in the boxes which where not generated from the loop before it. Can anyone help me with this?!Thanks in…See More

VB script to making a surface from a list of curves.

David Rutten replied to John Li's discussion Help with iterating Curves in VB

"There are several problems with your code. One of them is that the Random class should really be created either only once, or each time with a different seed. Another problem is that it is not possible to output a List(Of Point3d) which represents a…"

Help with iterating Curves in VB

Hi, I am new to scripting and grasshopper and have been trying to write a script for a simple vb button, which iterates a simple four point curve using loop. However, my script is only iterates one curve and then repeats it. The random numbers don't iterate themselves after each loop.
