# Fretboard / Decreasing Distance Over Space in Pattern Expression

Creator

Trying to go about making a guitar fretboard using the pattern feature and an expression - however I'm not sure how the expression would go.   Any advice would be great.  Ultimately would like to do something like this: http://www.mykaguitars.com/instruments/121/121-010.jpg

thanks!

What version of NX are you running?

If you have a simple increment you can just key in the "growth rate". This means that the distance between every pattern instance will grow by 20 (mm).

Spoken in math it will be something like d(n+1) = d(n) + x; x is my 20 and d(n0) is my first distance set up in the pattern dialog.

Thanks for this - I understand the concept but not sure how to set up the expression in NX - any chance for a screen capture/share?

Having entered your desired count and a starting pitch value, select the Pattern Increment icon:

Highlight the Pattern direction parameter and select "Add new set":

Enter in the desired incremental value and choose OK to return to the Pattern Feature dialog:

hey @josch and @BenBroad - thanks for the responses!  I was looking at your replies via email and I didn't see the screen captures - totally appreciate it!  I'm using NX for MAC and it doesn't appear to have the increment option in pattern feature.  Am I missing it somehow?

Click on the Dialog Options icon at the bottom of the dialog and choose "Pattern Feature (More)":

Ok I see it now.  Cool - a couple more questions: is there a way to have it decrement instead of increment?  Also, how could you have this affect other properties - like scaling or rotation?  thanks

Just use a negative value.
