Hi Alan Apologies for that- I thought if I could see it ok.... anyways here it is reattached. impressive spaghetti but no information can be ascertained as its too small detail but its from this original thread https://groups.google.com/forum/?fromgroups=#!searchin/xsi_list/convex$20hull/xsi_list/HcwOCOr2b_c/azmTxe3zlK8J hope that works Best Rob On 7 September 2012 16:47, Alan Fregtman <alan.fregt...@gmail.com> wrote: Hey Rob, You're linking to a private url for your Gmail pointing to an attachment.

Pretty sure there was a compound once, if not you might try Mr. LaForge's Convex Hull ICE node.

Polygoniser takes the nulls but gives blobs rather then a single mesh! Thanks for looking though! Cheers Lawrence On Wed, Sep 5, 2012 at 9:42 AM, Rob Chapman <tekano....@gmail.com> wrote: oh! ICE topo should be able to do this, :) but not sure how you are to build the polygon description from a set of random positions!? not so easy what kind of mesh are you after? if its not just a regular clean topology then you could simply put all nulls into a group and use the global.kini.pointpositions to feed into a polygoniser mesh. hth On 5 September 2012 09:17, Lawrence Pankhurst <lp3ds...@gmail.com> wrote: Hi guys, I thought I remembered a nulls2mesh script knocking about, can't find it anywhere! I've got a set of nulls and want to turn them into a mesh, ie position of each null becomes a vertex in said mesh! So anyone now where the script is or is there an ICE tool? Had a look on http://rray.de/xsi/ but couldn't see what I was after! Any help appreciated. Cheers Lawrence -- - Ciaran
