Grasshopper

algorithmic modeling for Rhino

Odd...

...I seem to be having trouble with some simple native functions, such as Sin(x), Cos(x), sqrt(x), for example...I'm getting a "Cos is not declared" (or Sin, or sqrt) error when I try to use these...I'm pretty reliant on trig functions, so this is a bit alarming to me.  All my old VB.NET components simply aren't running now.

I recently loaded the most recent build, but did so at the same time I moved from Vista to Windows 7...anyone have any clue what might be happening?

thanks,

Dave

You need to either type "Math.Sin(x)"
or import the math namespace, then you can use just sin(x)

Thanks, Daniel! math.xxx will completely work.

But...if I'm using the coder in GH, the "imports" section is greyed out and I can't add or edit text there. I'm curious: how do I go about importing the namespace in that arena?

Why and when did the requirement for this Math prefix become active.


Many thanks

I just noticed this as well. Hmmm as far as i can tell this was active since version 43, but i'm not sure. Is it possible to import the namespace?

Yea, I forgot that we can't simply type in "Imports System.Math" up there ourselves.
Maybe David can add this when he gets back.
