Is is possible to run Grasshopper in other IDEs like PyCharm?
@eduszh wrote:
Hello developers @piac,
I am not a big fan of the RhinoPythonEditor, so I am wondering if it is possible to let PyChamr do the same job? I followed the directions outlined in the following post:
However, when I run:
from Rhino import RhinoApp, RhinoDoc gh = RhinoApp.GetPlugInObject("Grasshopper")I get:
"C:\Program Files\IronPython 2.7\ipy.exe" E:/TEST_PROJECT_PYCHARM/TEST Traceback (most recent call last): File "E:/TEST_PROJECT_PYCHARM/TEST", line 6, in <module> SystemError: Unable to load DLL 'rhcommon_c': A dynamic link library (DLL) initialization routine failed. (Exception from HRESULT: 0x8007045A) Process finished with exit code 1May I know if this error is solvable?

How to unregister a python command
@cokepe wrote:
Hello
I´m getting this error. I know why happened, I change the name of the file command, so now rhino can´t find it.
The question is how can I fix this, so Rhino is able to find the correct file.
And also related, how do I delete a command…Thanks.

Trying to Delete selected Extrusions
@dylanbahnan wrote:
Hi, I’m sure this is a very basic question but I can’t seem to figure it out. I’m trying to modify an existing script to delete the extrusions from groups after it’s converted them from blocks (I’m using Dale Fugiers Script). At the moment it will convert the blocks to groups but then it deletes everything. Any help is appreciated. Here’s what I’ve got.
’ Local variables
Dim arrBlocks, strBlock, arrObjects(), nBound, strObject, arrExtrusions’ Get blocks to explode
arrBlocks = Rhino.GetObjects(“Select blocks to convert”, 4096, True, True)
If IsNull(arrBlocks) Then Exit Sub’ Explode the blocks
For Each strBlock In arrBlocks
’ Reset our array of objects
ReDim arrObjects(-1)
’ Explode the block
Call BlockExplode(strBlock, arrObjects)
’ See if any objects were added to our array
On Error Resume Next
nBound = UBound(arrObjects)
If (Err.Number = 0) Then
’ Group the objects
Call Rhino.AddObjectsToGroup(arrObjects, Rhino.AddGroup())
End If'Defines arrExtrusions' arrExtrusions = Rhino.ObjectsByType(1073741824, True) For Each arrExtrusions In arrBlocks 'Deletes Extrusions' Call Rhino.DeleteObjects(Rhino.ObjectsByType(1073741824, True)) NextNext
End Sub

Batch convert 2000 rhino files to 3ds and obj files respectively
@uaremycaptain wrote:
Hi~I am puzzled by the problem to convert around 2000 rhino files to obj and 3ds files respectively
I try to use AHK window automatic script to simulate the human click operation,e.g click ‘import’, assign path, click ok, and then wait for a few seconds to totally import, and then click ‘export’, well this is a little fool and clumsy, especially low efficientIs there any more efficient way to convert a huge amount of files?like 500 rhino files or even 2000 rhino files?The target format is 3ds and obj,I know to convert them in the same open file can be a disaster for CPU,this way i tried is inconvenient and anti-human-and-computer,if one step crash,all crash,and so do i
The core thought should be converting each of them one by one in queue aumatically by script .
Below is a simple example i want to show:
![rhino_convert_3ds]()
i think there must be some script to help me,BTW,i master python,so if you have any direction or good suggestion ,please tell me ,thanks !!!

Reduce Mesh - Export OBJ

Hi All,
I am extremely new at scripting and found a script online that does almost everything I am looking for…
The problem is that I need to work through a folder of files, opening each one individually and then reducing the mesh, and then Exporting to OBJ format.
I look at trying to find other script command and combining them, but was unsuccessful!
Can anyone assist with modifying the script below so it will automate the script process through an entire repository:

Importing layers via Rhino.FileIO
@Helvetosaur wrote:
Hi there,
I’m toying around with an “import layers from file” function. I am able to successfully import layers (including tree hierarchy, which is good) using the following code:
import rhinoscriptsyntax as rs import scriptcontext as sc import Rhino def ImportLayersFromFileTest(): filename=rs.OpenFileName("Choose file to import layers") if not filename: return #optional, doesn't change much #tbl_filt=Rhino.FileIO.File3dm.TableTypeFilter.None #no_obj=Rhino.FileIO.File3dm.ObjectTypeFilter.None #read_file=Rhino.FileIO.File3dm.Read(filename,tbl_filt,no_obj) read_file=Rhino.FileIO.File3dm.Read(filename) if read_file: layer_list=read_file.AllLayers for layer in layer_list: sc.doc.Layers.Add(layer) ImportLayersFromFileTest()This does work to import the layer arrangement without objects, which is what I want. But, some of the layer characteristics are not imported - notably the layer material assignment if any the linetype. OTOH, layer print color and print width are imported.
So the question is this: is there some easy trick I’m missing or do I also need to get the material table separately, add the materials to the file if they do not already exist, and then re-assign them to the imported layers? Same for the linetypes?
I also understand that I will need to do some checking for existing layers and possible conflict resolution, but that’s for later…

Reverse an equation
@Helvetosaur wrote:
Hi all,
I have the following formula for calculating the “scallop height” (h) with a spherical cutter of radius ®, given the “stepover” (x).
h=r-\sqrt{r^2-(x^2/4})
With my remnants of high-school algebra, I tried to “reverse” the formula to solve for x given a desired h. However, my formula does not give me an accurate result, so I must have done something wrong…
x=\sqrt{8*h*r-h^2}
So, does anyone know how to do this correctly?
TIA, --Mitch
