ey eventually recover and you can continue to working normally. This however is not very practical...
(Additional information: We have a virtualized Windows SPS environment, might this be the problem? Locally - on my hard drive - it works fine.)
Futhermore we've discovered the following bug/feature:
We export a cluster and reference it back into our .gh file, then copy the .ghcluster file to a different location and rename the copy (without opening or changing it), then also reference the copied version back into the .gh file. Now Grasshopper shows two clusters with two different file paths, but claims that they both are the same ("this cluster occurs twice in this document"). If I double click one of them, make a change and save, both clusters get changed, even though they are separate .ghcluster files.
This would follow the logic that David laid out in this entry (http://www.grasshopper3d.com/page/clusters09), that GH identifies a cluster not by its file name or location but by its internal ID.
An addition we would very much appreciate for the next GH update, would be the option to right click a referenced cluster and then not only be able to "update" it but to also to "relink" it to a new or different source.
Right now you have to rename or delete the .ghcluster file in order to relink a cluster via the update option. You can also overwrite the old cluster und update. However, sometimes we want to keep the old version or disentangle one of a clusters many instances and relink just one, with out loosing its various inputs and outputs by referencing the new version and reconnecting it.

f my list.I don't understand why, but I guess I must be too young user ^^In the original list, i have a path {0;0;0;4} with two index and after the random node, {0;0;0;4} has 88 index.Items are not correct?I would have a comparable structure has the right list on my jpg (photomontage...)How I can do that?Thank you in advance

akes the linear regression of the Schroeder integral over 30 dB worth of decay. Whether it is T-15 or T-30, they all seek to estimate the RT, which is always always the time it takes for sound to decay 60 decibels.
The website has benchmarks, for your reference. You can find them under the 'Pachyderm' drop down menu, under 'Benchmarks'.
Your model may well require millions of rays to be accurate. It sounds like a very large space. I'm sorry if that is an unpleasant answer. Sometimes it does help to have a computer with more cores to help with this. I have gotten up to 90% processor usage on a 12 core machine before.

hat differ in shapes, sizes and height the facade would be a mess. Some spaces need some light while other can't have any. I would like to have full freedom of creation inside the building, to make it as functional as possible. Thats why i decided the parametric "skin" solution would be best. Since the location has industrial past (factories made of brick) i decided that brick would give interesting result.
I tried creating the definition on my own but since i lack skill in GH i got some problems (especially multiplication of bricks and the diffrence between each "level" (half a brick on y axis) caused problems for me.
I post my simple sketch explaining the idea of definition i would like to create (sorry about quality):
1 - Brep - I would like to use 25x12x6cm (classic brick) but as well experiment with diffrent shapes - like the one on the right with hole inside - that would give more light. Thats why i think the best solution would be using brep for this definition.
2- Multiplication - biggest problem for me - I don't know how tall the wall would be, what will be the final shape of Brep (brick) and that's why i would like to manipulate this with sliders as well. All the walls are flat (maybe it would be easier to use surface?). As i managed to multiply the bricks easy way i don't know how to gain control over height of the wall - for example that it is 30 bricks high, but has each second row moved on x axis by the distance of 1/2 brick. I tried using Series but with no success. Could you help me with that please?
3 - Rotation - i would like to use image sampler for that so i can "paint" where i want more sun and where i dont need it at all (black and white). The rotation has to be limited to 180 degrees as well. Obviously i didn't get here yet, but i never used image sampler so if you could give me some advice how to use component and how to create such images i would be really grateful.
4 - More of a concept thing - since the connection angles differ from 90 degrees i will have to figure out how to connect the parts of the wall at sides ;).
I would like to ask you for help with the defintion, since i am totally stuck at step 2. I post what i came up with so far. Thank you for your time and help!
PS. I post an image that is pretty similar to one of options i would like to check for my building.

he concept, moving on to decision making and continuing with digital and generative design tools TO GET THE BEST SOLUTION for each problem.
WHY? The world is complex and ever-changing and we need to be able to handle the volume of information we receive and, of course, to find and choose the best solution. Therefore, we direct our ATTENTION TO THE CAUSE, and not only on the effects/solutions.
We will learn from NATURE, the only “company” that has not gone bankrupt in over 4000M years, and it’s GENERATIVE SOLUTIONS.
> OBJECTIVES <
The participants will work in multidisciplinary groups (ex. architect + designer + business manager + constructor + communication specialist etc.) applying knowledge management tools, different approaches and nature-based optimization methods.
Listed objectives:
1. Improving the generative way of TURNING AN IDEA INTO A PROJECT through problem-solving thinking
2. Discovering nature’s ways of shaping evolutionary solutions
3. Getting out from our comfort zone and working together with other professionals in groups in order to achieve better solutions: Multidisciplinary Design Optimization
4. Learning to use technology to manage information in the decision making process

Can anyone help me?…
ou will see all of the available components on a ribbon at once so there is no need to keep clicking drop down menus.
It's all about discoverability with GH. What if you're a beginner and don't know about the Create Facility (dbl click canvas) how can you find Extr?
Even if you hover over every component or use the drop down lists you will not see the name Extr appear anywhere.
Sure it makes sense that Extr is short for Extrude but it's also the Nick Name of Extrude to Point component
So you can easily miss the fact that one has a Distance Input verses a Point Input.
I think I made the move to Icons around about the move from version 0.5 to 0.6, possibly before. I initially thought that I would go back to text because I loved the mono chromatic look of the text but I soon realised that Icons were the way forward. The greatest benefit is speed. You don't need to digest and decipher every component (which is written 90 degrees to the norm).
I'm not saying you should move to Icons forthwith but at least consider that once you have a better knowledge and understanding of GH, Icons will set you free.
My top ten tips that I would highly recommend to anyone wanting to better themselves with GH.
1) Turn on Draw Icons
2) Turn on Draw Fancy Wires
3) Turn on Obscure Components
4) Use the Create Facility like a Command Line eg "Slider=-1<0.75<2" or "Shiftlist=-1"
5) Use Component Aliases to customise your use of the Create Facility eg giving the Point XYZ component an alias of XYZ will bring it up as the first option on the Create Facility as opposed to the other possibilities.
6) Try to answer other people's questions even if it's not relevant to your own area. By looking into solving a problem outside of your comfort zone and then posting your results it is very rewarding but it also lets you see the other approaches that get posted in a new light.
7) Take the time to understand Data/Path structures.
8) Buy a second monitor - There is nothing that can compare to real estate when working in Grasshopper.
9) Read Rajaa Issa's Essential Mathematics
10) Pick a panel in a tab on the ribbon and get to know every component inside and out and then move on. Start with the Sets Tab > List Panel…
even (0, 2, 4) then that means the point either never hit it, or went in and out again, meaning it's outside. If it hits an odd number of times, then it must have come from within originally.
The method implements this approach using the mesh bounding box, and then striking a polyline from your test point along a vector that is defined by the upper right corner of the bounding box + a vector of (100,100,100). In the case of your failing points, this is a result of their striking an edge very precisely, which gets counted as 2 hits instead of 1 (as it should be getting captured) and passing false:
Your best bet is probably to roll your own implementation, that tests for multiple vectors:
private void RunScript(List<Point3d> P, Mesh M, ref object A, ref object B, ref object C) {
BoundingBox bb = M.GetBoundingBox(false);
List<bool> inside = new List<bool>();
for (int i = 0; i < P.Count; i++) {
Polyline a = new Polyline(); Polyline b = new Polyline();
a.Add(P[i]); b.Add(P[i]);
a.Add(bb.Max + new Vector3d(100, 100, 100)); b.Add(bb.Max + new Vector3d(100, 150, 150));
int[] fa; int[] fb;
Point3d[] xa = Rhino.Geometry.Intersect.Intersection.MeshPolyline(M, new PolylineCurve(a), out fa); Point3d[] xb = Rhino.Geometry.Intersect.Intersection.MeshPolyline(M, new PolylineCurve(b), out fb);
inside.Add(xa.Length % 2 == 1 || xb.Length % 2 == 1);
checkA.AddRange(xa, new GH_Path(i)); checkB.AddRange(xb, new GH_Path(i));
}
A = inside;
}
