I’d like to extract the light weight mesh from an extrusion.
I see a GetMesh method, but I seem to get null for every enumeration value.
Refer attached. I haven’t found any other method to get mesh without converting to a brep.
Thanks in advance for any assistance.

I need to generate a large amount of color swatches (bitmaps) to be used in a GridView. In order to create them, i tried to build the bitmap like this:
bitmap = Eto.Drawing.Bitmap(20, 20, Eto.Drawing.PixelFormat.Format32bppRgb)
color = Eto.Drawing.Colors.AliceBlue
graphics = Eto.Drawing.Graphics(bitmap)
graphics.Clear(color)
The process to create 6 empty bitmaps (20x20 pixels) like above, takes 6 seconds which cannot be right. So i tried to clear the graphics with a solid brush like this:
bitmap = Eto.Drawing.Bitmap(20, 20, Eto.Drawing.PixelFormat.Format32bppRgb)
color = Eto.Drawing.Colors.AliceBlue
brush = Eto.Drawing.SolidBrush(color)
graphics = Eto.Drawing.Graphics(bitmap)
graphics.Clear(brush)
without any change in speed. So i tried to draw a rectangle in my color into the graphics object which seems to work very fast:
bitmap = Eto.Drawing.Bitmap(20, 20, Eto.Drawing.PixelFormat.Format32bppRgb)
color = Eto.Drawing.Colors.Red
brush = Eto.Drawing.SolidBrush(color)
graphics = Eto.Drawing.Graphics(bitmap)
rectangle = Eto.Drawing.Rectangle(0, 0, 12, 12)
graphics.FillRectangle(brush, rectangle)
but the result is a black bitmap unless i add this at the end:
graphics.Dispose()
As soon as this line is added, the bitmap creation process runs as slow as before. Running out of ideas, i’ve used bitmap.SetPixel(x,y,color) in a double nested loop as reported here which seems to run slightly faster but with more than 100 swatches to generate, takes too long to be usable.
How can i generate these color swatches fast enough ?
thanks,
c.

Hi, I’m trying to get an Eto form to show called by a script, but I get an “empty” form:
Here’s are the excerpts from the three scripts I’m using.
I’m importing all the necessary modules (designated by “import ...”).
I created dialogs before that did work, but in one script, so not divided over several scripts.
I think therein lies the problem …
Can anybody help me fix this?
MAIN SCRIPT
import points as p
p.add_points()
POINTS MODULE
import ...
import interface as i
points_list = []
def add_points():
...
create_point()
def create_point():
dialog = AddPoint()
dialog.ShowModal(Rhino.UI.RhinoEtoApp.MainWindow)
print points_list
class AddPoint(Eto.Forms.Dialog):
def __INIT__(self):
...
self.point_name = i.txb(None)
button_ok = i.btn('OK')
botton_ok.Click += self.button_ok_click
...
layout = i.dyn()
layout.AddSeparateRow(i.lbl('Name:', self.point_name)
layout.AddSeparateRow(button_ok, ...)
self.Content = layout
def button_ok_click():
global points_list
name = self.point_name.Text
points_list.append(name)
self.Close()
INTERFACE SCRIPT
import ...
def btn(...):
# define button
def dyn(...):
# define dynamic layout
def lbl(...):
# define label
def txb(...):
# define text box
@nathanletwory, @curtisw, I hope you don’t mind me adding you to my post, but you helped me a lot in the past and I hope one of you can tell me what I’m doing wrong. Thanks.

Hi everyone,
I was trying to use some grasshopper-based analysis results in my native Rhino Plugin. Let’s assume I want to use this data as some Head-Up Display using with DisplayConduits.
When I try to reach values using with this code; (It was just for test)
string componentName = "";
RhinoGet.GetString("Which component do you want to search?", false, ref componentName);
ComponentFunctionInfo component = Components.FindComponent(componentName);
string result = component.OutputDescriptions[0];
Console.WriteLine(result );
When I debug this code lines in Rhino typing componentName,
Although component exist in Grasshopper with its name, Components.FindComponent function returns null.
What am I missing?
Thanks in advence,

Hi Team,
we have a Rhino common plugin developed using c#.
we use to zip all the depended configuration files along with the rhp to create the installer .rhi extension by renaming it , installation works perfectly fine.
Our plugin need to connect to our api every time it launches and download and write a xml file .
There are some users those who are not admin on their machines, plugin is crashing for them.
The plugin is crashing because it not able to write file in the rhino folder “C:\Users******\AppData\Roaming\McNeel\Rhinoceros\6.0\Plug-inspluginname (6cef8511-a474-4679-af71-f4e919de7a76)\s”
is there any way we can customise the rhino installer to install it on a different drive or folder.
we cant get rid of this api call and downloading file at the moment.
can anyone suggest how to make installer which can point to custom location while installing?
if not , is there any other way to handle this apart from manual installation?
thanks,
Nevin

Hi @curtisw, all, I’m struggling to bind some custom class -CustomObj- properties to gridView DataCells in IronPython.
CustomObj class looks like this:
class CustomObj(System.Object):
def __init__(self,name=None,obj=None,active=False,type=None):
self._name = name
self._obj = obj
self._active = active
self.type = type
@property
def name(self):
return self._name
@name.setter
def name(self,value):
self._name = value
@property
def obj(self):
return self._obj
@obj.setter
def obj(self,value):
self._obj = value
@property
def active(self):
return self._active
@active.setter
def active(self,value):
self._active = value
CustomObjs are stored in an instance of MyModel class, in various properties that are .net BindableCollections.
class MyModel():
def __init__(self):
self.views = System.Collections.ObjectModel.ObservableCollection[type(CustomObj())]()
self.versions = System.Collections.ObjectModel.ObservableCollection[type(CustomObj())]()
def add(self,customObj):
if customObj.type == 'view':
self.views.Add(customObj)
elif customObj.type == 'version':
self.versions.Add(customObj)
I finally create a dialogClass with a gridView, and assign one of the MyModels observableCollections as gridView’s DataStore. Now, I’m struggling to figure out how I can bind a property of each item of the observableCollection to DataCells.
I tried with Binding.Property as follows:
class MyDialog(forms.Dialog[bool]):
def __init__(self,myModel):
self.cm = myModel
self.gridView = forms.GridView()
self.gridView.ShowHeader = True
self.gridView.DataStore = self.cm.views #set a bindableCollection as gridView DataStore
col_01 = forms.GridColumn()
col_01.HeaderText = 'view'
col_01.Editable = False
col_01.DataCell = forms.TextBoxCell(Binding = forms.Binding.Property[type(CustomObj()),System.String]('name')) ##NOT WORKING CODE!!
col_02 = forms.GridColumn()
col_02.Editable = True
col_02.DataCell = forms.CheckBoxCell(Binding=forms.Binding.Property[type(CustomObj()),System.Boolean]('active')) ##NOT WORKING CODE!!
#[code follows...]
Alternative, I tried using delegates as the example shared by @dale here . With this tecnique, it seems that TextBoxCell is correctly binding to ‘name’ property, but it fails to bing to the other DataCell of type CheckBoxCell.
class MyDialog(forms.Dialog[bool]):
def __init__(self,myModel):
self.cm = myModel
self.gridView = forms.GridView()
self.gridView.ShowHeader = True
self.gridView.DataStore = self.cm.views #set a bindableCollection as gridView DataStore
col_01 = forms.GridColumn()
col_01.HeaderText = 'view'
col_01.Editable = False
col_01.DataCell = forms.TextBoxCell(Binding = forms.Binding.Delegate[CustomObj,System.String] (self.myNameDelegate)) #THIS BINDING WORKS!!!
col_02 = forms.GridColumn()
col_02.Editable = True
col_02.DataCell = forms.CheckBoxCell(Binding = forms.Binding.Delegate[CustomObj,System.Boolean](self.myActiveDelegate)) #THIS MISERABLY FAILS!!! WHY. THE OTHER BINDING WORKS SO NICELY...
#[code follows... complete code at the end of the post]
def myNameDelegate(self,customObj):
return customObj.name
def myActiveDelegate(self,customObj):
nullableBool = clr.Convert(customObj.active,System.Nullable)
return nullableBool
I really can’t figure out how is done this with IronPython. All examples found out there were for C# and I can’t figure out how to translate them to IronPython.
Any help would be appreciated. Let me share the full code. Thanks!

How is this C# lambda translated into an IronPython lambda?
(PropertyListViewModel avm) => avm.SelectedProperty
The necessity of explicitly indicating the type is driving me nuts…

It is awesome to have in-place editing working for material content children, whether material-based or texture-based. Thanks for that.
However, from a user standpoint I think the material preview should remain focused on the current top-level material, rather than switching to preview a texture, or worse, a conceptually non-material content that is necessarily implemented as a material.
The idea being, if I am editing a material, and select a texture, I don’t prefer to see the texture previewed in 2D, but would rather continue to see my material, which of course will also reflect any changes I am making to the texture.
In the case of a non-material content, this is even more desirable. For example, we have a topcoat layer type of node that can be placed over various material substrates, and it would be far preferable, when selecting it to edit its attributes, for the top-level material to continue to be shown. In other cases, the content simply has no visual representation on its own.
Perhaps the last point suggests a need for there to be a fourth “utility” type of content, in addition to the existing texture/environment/material ones, but even in that case, this wish about keeping the top-level material in the preview would still stand.

I want cage edit command that can adapt to any form automatically.
As pic show, it is very hard to edit the form freely after bending.
Any idea?
Grasshopper can do that?
Thank you!

Dear all,
i’m new to scripting in rhino and don’t know the right syntax yet.
Perhaps someone could help with one inconvenience. 
I like to work with worksessions, but i am really bad in properly organizing the used materials in each file.
When it comes to combine them in a worksession there are multiple materials with names like “custom 01”. The first “custom 01” is a carpet, the next wood, the next simple black, and so on…
The problem is, that rhino assigns one material (texture, glossyness, whatever) to all “custom 01s”. So that now all “custom 01s” get a carpet texture.
Is there a simple way scripting a prefix to all file materials?
Means, i have file named 01_floor, 02_walls, 03_ceiling and i can rename all used materials in each file with the number prefix of the file, in order to get “01 custom 01” for the carpet, “02 custom 01” for the wood, “03 custom 01” for the simple black…
Thank you very much!
Seb.

I can see something weird happened inside openNurbs. I don’t know if it’s because Tibidabo’s anti-debugger code.

Some xNURBS customers ask Grasshoper because they need to automatically generate a lot of surfaces based on xNURBS on the fly and to speed up their designing process based on xNURBS. Only three simple APIs from xNURBS plug-in are needed to implement xNURBS GH, which can be used to develop a ton of surfacing tools (It is possible to combine the three APIs into one API.). If we export the C APIs, could xNURBS customers use these C APIs?

Is there a ghPython equivalent in RhinoCommon for the Grasshopper Linear Array component (or other Array components)?
I currently access the Linear Array component from Grasshopper using the ghpythonlib.components.LinearArray but I will probably not be able to use this Node in Code functionality once I refactor the Python code to C#. I want to make this original code future proof for the next phase.
If there isn’t a RhinoCommon equivalent, could somebody from McNeel post the definition from Linear Array that I can plug into my Python code using RhinoCommon?
Thanks.
