I would like to create scribbles at specific locations on the canvas; relative to the bounds of a group.
MetaHopper does this, but I’d like to do it in a ghPython component. I cannot find the attributes, like Pivot, for Special.GH_Scribble that would set its position.Where should I look for help on this?
Thank you,

Hello,
I am trying to import .dxf file via grasshopper with c# component. Everytime I run the script dialog box is opened to select a path. What I am looking for is…a) it shall take file path as an input and import it without opening dialog box.
b) I do not know if it is possible, but I want to have the imported .dxf inside grasshopper and not in rhino so only if it is necessary i ll bake it.Any help is this regard would be great!
here is the code i used to import
Rhino.RhinoApp.RunScript("_Import", false); // and the it opens up the dialog box to select path

So I decided to try messing around with Worksessions from Grasshopper, and I was looking for a way to switch Active model, adding models, removing models etc, but RhinoCommon doesn’t seem to provide much help on this:
https://developer.rhino3d.com/api/RhinoCommon/html/T_Rhino_DocObjects_Worksession.htm
Is Worksessions something that isn’t really covered or am I just not searching hard enough?

This is maybe problem with the number slider, it has to allow more digits behind the decimal point. at least to match the capabilities of Grasshopper.

I came across a weird behavior while I was trying to make a simple C# scripted component to append data on a new branch at the end of an input data tree (supposing, for an initial simplified case, that the tree structure had just one level so the branch indices are {0}, {1}, … {n}). I’ve tried to append data with 2 methods. One works as expected, while the other acted funny: when I tested it with a ‘Series’ component, the index of its last branch (the INPUT one) increases by one each time I re-plug it in the C# one.
This is weird and to me, I tried with new Series components, copy-pasting the C# into a new definition and it still messes with the Data Tree index of the input component. I am uploading it here in case this might expose a potential bug that needs fixing. I’m using Rhino 6, latest SR as of today.
See the screenshot (and the attached gh file) below.Weird tree behavior.gh (10.0 KB)

Hi everyone!
I need to trim a mesh on specified edges, I tried creating trimming solid (mesh/brep) in several ways but it doesn’t work well. I think that the easiest way is to unweld the mesh at some edges selected by indices and then explode the mesh without unweld it again, but there isn’t any component in gh to do that operation, you can only unweld a mesh by a range of angles.
In rhino it works with “unweld mesh edges + explode”, but you have to select the edges one by one with the mouse, selecting it by indices in grasshopper it’s gonna be really easier.anyone can help me? thanks

OK, I give up on DataOutput/Datainput.
I’ve had a look at splitting my huge GH definitions using DataOutput and DataInput and yes, they would have done the job, but only if :
- I could define the File name via an input (I need to concatenate file names), and
- Save and Read back data from (default) the same directory as the Rhino model (or the GH def), or from an optional (input) Path
I need to have full control of my “data flow” (which can vary, and can be complex) so I will have to write my own Data Output/Input components for my needs.
Q: But how do I save individual GH objects (do I have to bake them first?) to file (fast & compact format?) in the most straight forward way? Are there any code examples/links? Prefered File format? Etc. A simple (C#) example would get me started.
