Randomly Extruding [Voronoi] Surfaces

I am wanting to extrude surfaces to random heights (or ideally the heights would be indicated by image sampling - but this seems hard to come by). I have managed to sort of do this, expect only two of the surfaces randomly extrude, and the rest remain the same height. I have tried multiplication/jittering etc but nothing has seemed to help.

Any ideas/suggestions would be much appreciated!

Dan

Hi Dan,

The reason you couldn't do it was because the number of random value didn't match up with the surface you have.

one way of doing it is to match the 'number of value' in random with the 'list length' of the surfaces.

I also added a part to let the surface extrude to a surface so it can be smoother.

pls take a look at the files

you also had a whole lot of duplicate surfaces in your input, make sure you file is clean otherwise the duplicate one will not only slow down your computer but create problems later if you are doing more operations like boolean.

I cleaned it for you, but you should check it your self from now on, before you reference geometries in rhino, you should, in rhino, use 'SelDup' command to select duplicate and delete them.
