ct rotate by 360 degrees,
the fourth object rotate by 270 degrees,
the fiveth....
all objects rotate with multiples of 90 degrees at random sequence..
Can you help me?
Thanks a lot

" (idiomatic) and easy way of doing things.So here come some basic questions:
Is there a way to create custom components by grouping an existing sub-network together? I'm looking for a way to re-use parts of a program (something similar to subroutines), and to make the network look less cluttered. I found that it is possible to group components (ctrl-g), but this still displays them as separate blocks (too much clutter), and provides no way to re-use a sub-network in such a way that if it is modified in one place, all it's instances (all the places where it is re-used) also get modified.
Is there a component that does nothing, just passes a signal through? Suppose I need to connect block A to blocks B1, B2, B3 (all three get the same input). Then I change my mind, and I decide to connect block C to these three, not A. In this case it will be necessary to change three connections, not just one. I'm looking for an easy way to do this by a single rewiring, not three. (This came up in a practical situation).
Finally, a related question: is there a component that acts as a switch, so I can choose which signal it passes through out of a possible set of choices? For example, suppose that a set of objects can be coloured based on a number of different properties (size, positions, rotation, etc.) I'm looking for a way to switch between these very easily, without the need to do much rewiring.
Thank you in advance for any replies / useful comments, even general ones on how to easily structure a large Grasshopper program/network.…
see in my bottom post image there is only one isocurve showing in U and V.
In Grasshopper there's no surface rebuild? Well, the same old Grasshopper Patch command will let you specify spans I guess, to make a surface from a planar curve, but it won't work for things with holes since they will just fill in!
You can recreate a surface painfully by untrimming, adding many UV points, rebuilding from those points, then retrimming with the original surface info, but the retrimming simply fails.
If you make a planar surface from a curve in Rhino, you end up with utterly no point editability:
No wonder my CreatePatch tests were a failure. The starting surface could not be distorted except in the extreme case of moving four corner points!
I have no idea how to successfully rebuild a surface akin to the Rhino rebuild command. It's great to be able to prototype in Grasshopper, but with Python I can rebuild easily ( http://4.rhino3d.com/5/rhinocommon/?topic=html/M_Rhino_Geometry_Surface_Rebuild.htm ;), so I guess I should start a collection, like peter, of little script components for prototyping with.…

Simpsons episode were Bart goes into a mall and in the time he goes in and out of a shop all others have been turned into Starbucks.
I personally don't like it but you can't say they are crushing all competitors because, as far as i know, all owners of those software packages voluntarily sold their property for a good price. I would actually be more worried that an antitrust lawsuit was filed against Autodesk.
For example, this is what happened with Rockefeller's Standard Oil:
The antitrust case against Standard Oil also seems absurd because its share of the petroleum products market had actually dropped significantly over the years. From a high of 88 percent in 1890, Standard Oil's market share had fallen to 64 percent by 1911, the year in which the US Supreme Court reaffirmed the lower court finding that Standard Oil was guilty of monopolizing the petroleum products industry.[32]
The court argued, in essence, that Standard Oil was a "large" company with many divisions, and if those divisions were in reality separate companies, there would be more competition. The court made no mention at all of the industry's economic performance; of supposed predatory pricing; of whether industry output had been restrained, as monopoly theory holds; or of any other economic factors relevant to determining harm to consumers. The mere fact that Standard Oil had organized some thirty separate divisions under one consolidated management structure (a trust) was sufficient reason to label it a monopoly and force the company to break up into a number of smaller units.
To economists, "predatory pricing" is theoretical nonsense and has no empirical validity, either.
In other words, the organizational structure that was responsible for the company's great efficiencies and decades-long price cutting and product improving was seriously damaged. Standard Oil became much less efficient as a result, to the benefit of its less efficient rivals and to the detriment of consumers.

(Beware, that site is very ideologically charged)…
points within the bounds of the site boundary and use each location as an attractor point controlling a variable at each point in the grid (radius of a circle/height of a cube/colour based on a gradient etc.).This would be based on proximity to the attractor points with the effect of each attractor point essentially scaled by the percentage associated with it. For example a location with 88% visitor rates would have a more dramatic effect than a location with 26% visitor rates.
I've had a bit of a play around but can't seem to get beyond the point of what is shown in basic point attractor tutorials online. I'm definitely a novice.
Here's how I figured it would be done:
1) Create a grid of source points within a boundary curve.
2) Select 18 pre-defined attractor points.
2) Measure the distance between the source points and the attractor points.
3) Invert this data so that variables increase with proximity rather than decrease.
4) Give each of the attractor points a strength value from 1-100% based on the visitor rates.
5) Use the scaled data to control a variable at each of the source points.
6) Create some way to control the drop-off rate of the effect from each point.
It is at step 3 that I get completely lost.
I hope my description is clear. Any help would be greatly appreciated,
Adam

vided with U and V into line segments (i'd prefer to use that method instead of rectangular grid). These segments in U direction would then be rotated around V lines segments with min value of 0 and max value of 90 degrees, according to attractor (i'd like it to be image sampler in the end but for now im trying with point/multiple points). These lines would then be lofted
I post the definition below
Here are my problems (i marked them in definition):
1)i managed to get U direction line in every second row, i dont know how to get the lines between the rest (i tried shifting list, but didnt manage to get the right result).
2)Harder part - id like to measure distance between attractor point and a bottom point of lines. Than i would like to transfer it to rotation this way (distances used just as example): distance 0-20 - angle of rotation 0degrees; distance 20-30 - angle of rotation 1-90 degrees. I have no idea how to transfer it into definition. I also have problems remapping numbers to 0-90 value.
3)I'd like to do that later but i'd also like to use black-white image sampler as white - 0 angle of rotation, black - 90 degrees. I never experimented with image sampler and would be grateful for some advice how transfer colors into degree values.
I politely ask you to help me (especially with first two points i mentioned). I'm not asking for a ready definition - I would like to understand where my mistakes are.
Below i post a picture of something simmilar (although im trying to rotate it by edge, not by center line)
Pardon my english, thank you for your time and help.

ectural context.
We will work with 5 projects that meet the conditions to be re-thinked nowadays in parametrical terms. { FOA : World Trade Center / MAD OFFICE : 800M Tower / TOYO ITO : Relaxation Park / FOSTER & PARTNERS : Gherkin Tower / FREE : Soumaya Museum }
We will produce dynamic objects defined by parameters and modified in realtime.
We will learn to discretize, facet and panel in a non homogeneous way.
We will work with restrictions to determine our shapes, obtaining unpredictable results.
And we will take the control of what we produce : by measuring , visualizing and optimizing our parametric forms.

the most advanced surfacing commands. In addition, you'll learn concepts and features of Grasshopper at an accelerated pace in an instructor-led hands-on instruction environment. The advantages of using Grasshopper in preliminary design and concept development come to life since the students will be able to create their models on a 3D printer and a laser machine.

nd it was revolutionary at that time (3rails and then 4 rails and no naked edges whatsoever, and it could Boolean 1000 stones in less than 2 seconds!) I made my living and an office at Madison Avenue because of it and it is still not understood because of its simplicity and lack of sophisticated tools, but the power is all behind the veil.
Now I'm totally in Rhino due to its evolution and conformity in the industry and....GH of course.
Just after getting SolidThinking (an Italian monster used by Bulgary, Cartier, Nike etc.) I saw for the first time the components of Explicit History (GH original name) and I knew it was going to be the one.
So more money out of the window (or I should say "out of Windows XP")
I worked at the bench for almost 30 and this has been my way out and an adventure that is ever expanding.
I started with GH by making settings and connectors. Then Shanks, bands.
I used it for repetitive simple work while exploring what the advanced users were doing with it.

is actually the different or "extra" in this profile, which is the problematic areas. (one area is exemplified with red arrows, - but it is the different as such). The offset seems to be made in 90 degrees and of course it will cross the surfaces...
I would like the object only to be shelled inside. I need a thickness to make a 3d artefact by 3d printing (which will be a container). If you suggest another approach it is just fine. If it can be done with offset I need it to executed as a solid shell.
If the "mesh thicken" tool is used it could be great if it just made it thick in one direction - inside, but it makes it at both sides of the surface..also if you work with negative numbers...
Hope you have an idea. Thanks anyway for your time and reply!
