I am proud to announce the first release of Grasshopper components to output GCode for 5-axis machines. At the moment it is simply a collection of clusters and scripted components, but it will become…Continue

I am proud to announce the first release of Grasshopper components to output GCode for 5-axis machines. At the moment it is simply a collection of clusters and scripted components, but it will become a proper plugin. This is joint work with Santiago Perez. There is a lot more information to be found here:…See More
Edmund Harriss replied to Edmund Harriss's discussion 2d list culling and accessing mid levels of trees"Dear Danny
Thanks for your help with this. I agree that there are work arounds, and you have been very helpful with showing me what they might be. I do feel however that there are more elegant ways to deal with some of this. I believe my next…"
Danny Boyes replied to Edmund Harriss's discussion 2d list culling and accessing mid levels of trees"Hi Edmund,
My personal preference would be to try and change the geometry further up the chain before it got so convoluted eg flipping the direction of a curve before dividing etc.
But if I had to try and manipulate…"
Edmund Harriss replied to Edmund Harriss's discussion 2d list culling and accessing mid levels of trees"I am certainly learning a lot with this! Thanks for helping out.
I hadn't played with accessing the addresses directly like that. It could be powerful. Unfortunately the output is simply a list of addresses, loosing all the structure…"
Danny Boyes replied to Edmund Harriss's discussion 2d list culling and accessing mid levels of trees"A List of [Lists of Lists] is the output of the Param Viewer component. You can manipulate this with cull patterns, dispatches and Nths etc. like any other list. and put the results back into a Tree Branch component to select only those…"
Edmund Harriss replied to Edmund Harriss's discussion 2d list culling and accessing mid levels of trees"OK, so the rule is:
Compatible tree structures: map equivalent branches.
Incompatible Tree structures: forget structure and just count elements.
Is there any way to think about lists within the tree at different levels? In other words…"
Danny Boyes replied to Edmund Harriss's discussion 2d list culling and accessing mid levels of trees"Grasshopper will try and match the order of the list not necessarily the Paths. {0;0} first in list A, {0;1} second in list A. {0;0} first in list B, {1;0} second in list B.
I suppose its that way so that you can supply lists with vastly different…"
Edmund Harriss replied to Edmund Harriss's discussion 2d list culling and accessing mid levels of trees"Thanks for the comments, especially the work around, I had missed that trick with the path mapper. Also apologies for the bad use of language with "reverse", I was thinking about the order of indices.
In the final section,…"

I am a mathematician, raised on the list handling in Mathematica, and am working on getting my head round the list model of grasshopper. This has a lot to recommend it, especially simplicity; however there are some things that I feel should be easy, but I where I cannot find an elegant solution. I have attached an illustrative example, what am I missing?The idea is that I have a list of lists and want to cull each, but want a sequence of cull patterns for the lists. Say the cull pattern for the…See More
