Google Image Result for. Data Matching two tree's with different structure. So I h ave two trees that have different similar structure in the {A} level, but one has a {A,B} structure, and i want the component "intersect curves" to match the curves based on {A}.
Ultimately, I want the output points to be grouped by the line they came from. So, blue rectangle intersects the 4 lines, all the points would be located in {2;0} n=2 {2;1} n=2 .... etc. Any suggestions about how I would go about doing this? Here is the image again as an original. Swing Data Tree. Data tree operations (also a small series of questions) Hello, I was wondering if there are operations on datatree as I encontered some difficulties (maybe these are dumb questions): 1) first, let's consider a datatree with 3 branches with 2 components: It could look like this in a panel question: can you operate on elements between branches?
By default, when you apply polyline, it will connect the elements inside their branch. 2)If we have 6 elements (A,B,C,D,E,F) at the same level or issued from a flatten operation, how do we create a tree like this one: Path Mapper Component - what are "placeholders"? 3D interference field question. Subdivide Down Paths With Path Mapper. Split List Every Nth. Data tree matching. Curve Parameter bug? Cross Reference; what is it, how does it work, why would I need it? As of Grasshopper 0.9 components no longer offer a Cross Reference option in their pop-up menus.
This feature was removed because I felt it was not flexible enough. Now, you can achieve Cross Reference matching with a dedicated component which creates combinations of items. You can find the [Cross Reference] component in the Sets.List panel. When Grasshopper iterates over lists of items, it will match the first item in list A with the first item in list B. Then the second item in list A with the second item in list B and so on and so forth. We can denote the behaviour of data cross referencing using a table. Sometimes however you don't want all possible permutations. If we apply this to our {A,B,C}, {X,Y,Z} example, we should expect to not see the combinations for {A,X}, {B,Y} and {C,Z}: The rule that is applied to 'diagonal' matching is: "Skip all permutations where all items have the same list index".
The four remaining matching algorithms are all variations on the same theme.
Planar Surface Component. Hi, I am a little disappointed that the planar surface component doesn´t work like the used icon is promising. The icon shows a bunge of curves and lines which are overlapping at the end. Of course they need to be planar, but in GH it does not work with overlapping curves. Is there a trick to activate this function? I hoped this component will work similiar to the "boolean" curve in Rhino which creates a closed curve based on a bunge of overlapping curves - no matter if open or closed. any tips or workarounds are welcome.... thanks Tags: closed, curves, open, planar, surface ▶ Reply to This.
Path Mapper Help. As a result of a request please find a series of examples for using the Path Mapper component.
The First installment of this is showing the Path Mapper imitating some already existing components. Flatten, Graft, Simplify and Flip Matrix. There is also an additional example showing Integer Divide to which there is no existing component. For those uninitiated in the dark arts of pathmapper the component can be found on the Sets Tab> Tree Section with the icon of a red cube. Section 8: The Garden of the Forking Path of the Grasshopper Primer 2nd Edition is dedicated to the Tree Structure implemented in GH v0.6. UPDATED to correct an error in the Flip Matrix demonstration path_count should be item_count. Updated: 2011-04-20 Replace Branches Not sure if it's right to include this here as its actually encouraging you not to use the Path Mapper, but sometimes there are benefits to being able to keep the definition free from restrictions like the Path Mapper.

Dynamic Data Tree Path Mapping? So by now I'm quite comfortable using the path mapper to manipulate data trees, but there are a couple annoying things I always find myself having to work around, and I wondered if anyone had found better approaches to either situation.
I frequently have to partially flatten a tree by discarding one or more of the branch levels. (i.e. Path Mapper help needed:Split Surface with 14 surfaces and 70 curves.
