I would like to take the contour lines that I have imported from a pdf file (which means they are all in a single plain) and spread them out by a set interval. If someone can write a python script that would take would allow the lowest and highest contour lines to be selected and then have the interval distance be specified that would save a great amount of time.
Thank you,
William
Itâs spelled plane, not plainâŚ
Hi William -
Not a script, but a way to do this somewhat quickly the manual way:
-wim
I was going to post this before my laptop gave out this morningâŚ
The problem is that in V8 currently, vertical nudge with the PageUp/PageDown keys is broken - and has been for a long time despite my repeated requests to fix it. It seems to work now with simple PageUp/Down, but not with Ctrl+ or Shift+ - which simply zoom the view. So the linked method can sorta work if one makes sure to set the interval as one needs for Nudge without Shift or Ctrl.
It does work of course with the Gumball, just less convenient and more clicking.
You must have a later version than me here. Itâs not working in SR18 (not SRC). Probably only very recently fixed.
Also not working in the current SRC 8.19.25112.13001, 2025-04-22
I donât see any indication of this having been fixed in the YouTrack item.

Hi Mitch -
I now tested on 8.16 and 8.17 on macOS and that works fine there as well.
You must be running into something else. Does this behave the same across all schemes that you have?
-wim
Iâm on Windows⌠And yes, on all of my computers. Will test on Mac 8.19 in a bit.
My screenshot and first reply were from Windows.
On macOS, I donât need to uninstall a version to run an older version and I can very quickly go back to all service releases of Rhino 8âŚ
With Fn + Ctrl + Shift, plus the up/down arrows it works here on Mac 8.19 SRC.
However, it is definitely NOT working here on any of the Windows machines I have, US English OS with Rhino running in English, French or German. I also tested on a machine that has an Italian Windows OS but running Rhino in German, same thing.
Only Nudge with no modifier key (no Shift, no Ctrl) works as it should with PageUp/Down.
As I stated previously, the Youtrack item does not say âfixedâ.
The first series is with Nudge + PageUp/Down alone. The second is with Shift+, the third is with Ctrl+, and the last again with only PageUp/Down
Looks like we have been on different pagesâŚ
From
and
⌠I assumed that only PageUP and PageDown were being used. Not in combination with other keys.
-wim
From my first postâŚ
I made a tool for this 12 years ago, but it was a mess, so I cleaned it up a bit but didnât have much time. It can be made smoother, but it isnât half bad. So please contribute if you like guys.

Thank you for info. I have had some success using the distribution command and setting a distance in the spacing option. I believe that this only works if there is a single peak and trough selected. Curves get jumbled otherwise.
I am out for beer an music now, so maybe someone else ca take a look?
Hi William -
How are you running this script?
When you run EditPythonScript and copy-paste the code from the collapsed part of Jørgenâs post, it should run.

Hi @William15
you got it working?
