Plans to update github for rhinocommon?

The rhinocommon github repository has been quite helpful for me,
Are there any plans to update the source code? Or is it an experiment that is discontinued with Rhino 6?

InstanceObject.Explode strips user text from object attributes
@andheum wrote:
This appears to be a problem in both Rhino 5 and 6 - Attributes-Attached User Text is missing - this same data is present in the InstanceDefinition.Objects() Attributes properties.
To reproduce, make a box, assign it attributes user text, make it into a block, and run the following C# script in grasshopper:
private void RunScript(object x, object y, ref object A, ref object B) { Rhino.DocObjects.InstanceObject block = RhinoDocument.Objects.OfType<Rhino.DocObjects.InstanceObject>().First(); RhinoObject[] objs; ObjectAttributes[] atts; Transform[] xforms; block.Explode(true, out objs, out atts, out xforms); A = atts.SelectMany(a => a.GetUserStrings().AllKeys); B = block.InstanceDefinition.GetObjects().SelectMany(o => o.Attributes.GetUserStrings().AllKeys); }You’ll see that the A output is empty, while the B output has the specified user string keys.

Changing rhino unitsystem

Hi all,
I am having troubles trying to convert one script from python to c#. I realized that I have to change all of the structure. The code is about units. I would like to have one tool that notify me which units I am using in Rhino. here there are the scripts that I made. Also, I would like to know what the syntax for units in rhino is.
and here is the python script that I want to achieve in c#
thanks in advance for your help.

Rhino 6 Plug-ins - Construction Plane error
@UtsMicke wrote:
Rhino 6 Plug-ins
I use function “doc.Objects.AddText (sText, Plane, Height, Font, False, False)”
when I import and assign Plane a value“Dim Plane As Rhino.Geometry.Plane = doc.Views.ActiveView.ActiveViewport.ConstructionPlane ()”
I get the result {Origin = 0.0.0 XAxis = 1.0.0, YAxis = 0.1.0, ZAxis = 0.0,1}
everything works well
but if I open, I get this result ‘doc.Views.ActiveView.ActiveViewport.ConstructionPlane ()’ threw an exception of type ‘System.NullReferenceException’
and the program stops

RhinoCommon: GetObjectList and NameFilter

Hi,
I am using
GetObjectListto collect Rhino Objects withObjectEnumeratorSettings.
I need to collect objects with few names.
Currently I am usingNameFilterproperty for passing one name I am looking for.
That means the following: if i have 10 names to look - I need to runGetObjectList10 times.Is it possible to add option to use array of names for
NameFilterproperty, so that GetObjectList is executed only once?Thanks,

Is there any difference in the template that we have to modify if we want to develop a Windows Form App? I know we need to add the line
using System.Windows.Forms;.

Linear Dimension behaving strangely

Inconsistent behavior when creating breps
@rnjthmhnkl wrote:
I am trying to create breps with NurbsSurfaces with data (exported) from another modeling application. I tried, creating the brep from scratch but it proved very difficult to create a valid brep from raw data. But if I try using built in methods for creating and trimming breps, I am getting validity issues like following:
strong text
"cv[0*cv_stride + 1] = -1.#IND is not valid.\nON_NurbsCurve.m_cv[] is not valid.\nON_Brep.m_C3[0] is invalid."What’s even stranger is that this issue is not consistent, roughly every 1 out of ten attempts the same code produces a valid brep, with the same raw data ! If I try to put a break point and step through the code, it creates an invalid brep, then I move the execution point to an earlier line of code and run the brep creation line again, it creates a valid brep.
Can anyone explain to me what I am doing wrong? How can I reliably create a brep from raw data of surfaces and trimming curves? Any help is appreciated, thank you very much!

Box.Contains(Box) Check for Coincident Boxes?

Hi All,
I’m attempting to implement the Box.Contains(Box) method to check for coincident boxes. The API states that this method will return:
true if the box is on the inside of or coincident with this Box.
I might be misunderstanding what exactly is meant by coincident here, but am getting a
Falsefor cases like the left one here (I did try out a bunch of higher/lower Rhino document tolerances with the same result):
180404_BoxBoxContainment_00.gh (6.0 KB)Is this the expected behavior?

Bug in ApplyUvwTransform?
@Simon_Weinberger wrote:
Hi there,
Attached is a file created with Rhino 5. Just a simple box with the default stripe material applied. ApplyUvwTransform returns false, but the UvwTransform seems to be used in the viewport. It returns true after I change the values.
I have noticed that the same file works OK when opened with Rhino 6. Can you confirm that the bug is fixed in Rhino 6? And what about any possible updates for Rhino 5?
Thanks,

Im using the template of the DigitizerPlugin for RhinoCommon v6. and adding/changing the next code

Custom RenderMaterial Dispose Function called several times even if the material is not present, and not called when intended
@alonso.rosado wrote:
Hello there!
Im sorry if the title is is a bit convoluted, and somewhat long.
Im marking the actual questions per se in bold, though I think their context is necessary.
I’ve been messing around with the rendermaterials and been trying for them to generate some custom info, in an external container, that was supposed to be deleted when the material is deleted from the scene. For that I overloaded the Dispose function to delete the external info from its container.
When I saw that the data were not deleting properly, I proceeded to debug and discovered a couple of things. First, there is a lot of calls being done to my custom RenderMaterial even if its not present in the scene, and this is messing somewhat with my external data by adding extra unnecessary instances. Why is the RenderMaterial constructor being called up to six times to generate a single render material?
This gets cleand up eventually when the corresponding dispose functions get called, but in certain cases (due to code on my side) it leads to undeleted info.
The trouble comes when, even it the material is deleted successfully from the material list on the UI, my data don’t dissapear properly.
I imagine the material might not be deleted for Undo/redo purposes, but if that is so, how would you suggest me getting my data deleted? I can manage the undo/redo on my side, but I’m somewhat confused on how would I get the proper events to signal me to do so and why the materials are created so many times.
Thanks in advance

Rhino 6 C++ How to Detect Memory Leaks?
@lukeniwranski wrote:
Hello,
What is the recommended method for finding memory leaks in a C++ plug-in written for Rhino 6?
Please correct me if I’m wrong, but for Rhino 4 and Rhino 5, the SDK provided a copy of Rhino_d.exe that was linked with the debug CRT library. But from what I can tell, Rhino 6 doesn’t do this. The manual migration guide indicates to delete the old Debug configuration and just use the PseudoDebug configuration instead (which uses the non-debug CRT library). Because Rhino now uses the non-debug CRT, all C++ plug-ins must now also use the non-debug CRT.
How can we detect memory leaks without the debug CRT and it’s suite of debug allocation/deallocation tools? Is there a workaround or alternative to this? Are there any plans to re-introduce a copy of Rhino_d.exe with the C++ SDK to allow for linking with the debug CRT?
Thanks,
-Luke
