breaking a list item down

i imported a csv file of x,y,z values into grasshopper and wanted to create points out of it. however, when i try to break the list down (say, to get just x values), it still gives me all three values in each list item. how can i break the list item down further.

image attached: the csv values are in the panel on the right, and i can't seem to break the list item on the left down anymore.

thanks.

Read through this discussion for an explanation and if you specifically want x values try the following expression:

format("{0}", x.x)

thanks for the reply.

the expression formatting has no effect on the list. i think it's because my list is being read as strings rather than numbers. is there a workaround to this? i've attached the csv too. thanks.

Shahed,

The file will be read as loose String (one per line).

If you feed them through a Point component, do you actually get the points on screen?

Hi David.

the file does read as loose strings, but it gives me an error (data conversion failed from string to point) when i feed it through the point component.

i couldn't get it to work with the exact setup, taz. so i reinstalled grasshopper and it works now..

thanks for helping out.

I think I made the string->point converter smarter in one of the more recent versions. You probably had an older version.
