Hi,

I add N attribute in point wrangle to a box without N attribute.

vector @N= {0,1,0};
vector @n= {0,1,0};

But the result N is not {0,1,0} , it is values by automatic calculated.
And the n is {0,1,0}.
Why?


Another question, I want set N value if no N bounded . But this code may not worked.

if(!isbound(“N”))
{
@N = {0,1,0};
}

How to do it ?

Thanks!
