Please look at this file: Dropbox: Brickwall

By my self, I don`t no why.

It appears there is no domain defined for the Range ‘D’ input?

I´m just beginning with grasshopper and i’m new in this forum. So sorry :slight_smile:
But in the youtubevideo the author does not change something at parameter D. So what domain I should choose?
Ps: and also sorry for my english…

the second problem is that the expression in the range function is fail.


#5

By default, Range ‘D’ is “0 to 1”. I have no idea how it got disabled.

The expression should be “x-1”, not “n-1”.

I could cut out the mistakes. Thank you.
Have a nice day.

In old versions of Grasshopper the variable used in parameter expressions was the parameter nickname, this was changed a while ago to always be x. Old files containing expressions are converted automatically, but if you type new expressions into new files then you need to always use x.
