"You could also maybe create a shallow duplicate of the tree. That'll be a lot faster if the tree contains things that take a long time to duplicate like Meshes or Breps. -- David Rutten david@mcneel.com Poprad, Slovakia"

Tree - list - tree

Hello all, I'm trying to write a little method which should map a list of objects onto an existing tree structure.Basically, I would like to take a tree and flatten it into a list List<IGH_Goo> treeList = tree.FlattenData();I would then like to modify the items in the list, and map the individual items into a new tree which has the same topology as the original tree. Each modified item should take the same place as it had in the original tree.I'm doing this as I have a lot of legacy…See More

Florian Frank replied to Daniel Gebreiter's discussion GUID of an object

"Hi Daniel, The guid is a property on every RhinoObject. Every RhinoObject has another Property "Geometry" that is assigned with GeometryBase information. In your case a Point3d Type information. Once you reference a geometry to GH you can…"

GUID of an object

Hello all,this might be a silly question, but is there a quick and easy way to retrieve the GUID of an object in Rhinocommon? A curve or a point for example?I guess they are only assigned once added to the document? But does the geometry store its GUID? Is there a simple way of determining it I'm not seeing, something like... Point3d pt;Guid guid = pt.Id;//points have no .Id property! How else can I get the guid of an object? Many thanks for any pointers!DSee More

Preview geometry from custom class

Hi, I’m trying to preview data from a custom class I’ve written. However, as soon as I include it in my code, Grasshopper just freezes up (it goes pale white, similar to the behavior when calling an infinite loop). Here’s what I’m doing:The custom class I derive from GH_Goo<object> and I make it inherit from IGH_PreviewObject. I override IsPreviewCapable, ClippingBox, Hidden, DrawViewportWires and I create some PreviewArgs from some lines created by the class, as shown in the code…See More

multiple type input/output from custom components

Hello there,I’m trying to pass an array of object arrays which contain different data types between two grasshopper components. Not sure if I should be doing this at all, but I thought I'd try! COMPONENT 1: - the user inputs a line (curve) and a length (double). It stores the start point of the curve and the length in an object[]Input parameters:pManager.Register_CurveParam( "Line", "Line", "Line to get start point of"); pManager.Register_DoubleParam("Length", "Line Length", "Length of Line to…See More
