Switching GetPoint and GetObject
@kitjmv wrote:
Hello !
I would like to know if it is possible to switch between GetPoint and GetObject when executing a command.
For example : I have a command for draw a box. I would like run the command then pick a point or press special key for selecting a vertex corner.
Thank you,

Is there a way to prevent purge of certain blocks?
@D-W wrote:
As in the topic - i want to prevent deleting blocks which were created by my plugin on purge command is there any way for doing this?
I mean of course i can listen to commands and take action like:
Command_BeginCommand / Command_EndCommandto add those to doc and then delete them ( can’t just re-add them after purge cause guids will change ) but maybe there other better way to handle this discreetly?

Restriction of ObjectType in RhinoCommon
@kitjmv wrote:
Hello,
I can see in the source file that
ON::object_type(C ++) andRhino.DocObjects.ObjectType(.Net) is just a direct integer conversion.so I set the
ON::object_type.brepvertex_filtervalue toGetObject.GeometryFilter:var go = new GetObject (); go.SetCommandPrompt ("Select"); go.GeometryFilter = (ObjectType) 0x100000; go.GetMultiple (0, 0);And this works !
If
GetObject.GeometryFilteris just a wrapper around the c function, whyRhino.DocObjects.ObjectTypecan not set a BrepVextex ?And I have another question.
In .Net, I can not select extrusion vertices withGetObject.
How can we do that?Thank you

Usually we have the answer in the day or the next day.
Sory for my question, but i see this cathegory is very inactive.Maybe McNeel’s people went to a seminar or maybe there is another place to ask a development question with RhinoCommon?

C++ and Grasshopper passing native variables from one component to another
@Petras_Vestartas wrote:
Hi,
I am wrapping some native C++ library variables to C#.
Before I had one C# component where I had everything working fine calling CLI wrapped variables and solver. But now I want to distribute my code into multiple components.The thing is that I disposed some variables by placing them into brackets so that jointElementMatsSet and ele_link_tnl2 are deleted. I could also call Dispose method.
The small bit of code is here:{ var jointElementMatsSet = new OpenSees.Materials.Uniaxials.UniaxialMaterialWrapper[] { Axial_perimeter_long_leftMat, Shear_1_perimeter_long_leftMat, rigidmattagMat, FreemattagMat, FreemattagMat, FreemattagMat }; var ele_link_tnl2 = new OpenSees.Elements.TwoNodeLinkWrapper(2, 3, 16, 1601, dirIds2, jointElementMatsSet, new OpenSees.VectorWrapper(new double[] { 1, 0, 0 }), new OpenSees.VectorWrapper(new double[] { 0, 0, 1 }), new OpenSees.VectorWrapper(0), new OpenSees.VectorWrapper(0), 0, 0); theDomain.AddElement(ele_link_tnl2); }But now since I want to distribute different classes into different components I have a question:
Can I create one variable in one component and dispose it in another one?
More simply: when two components are connected and second component receives the variable, is it duplicated or it points to the same memory location?

Overriding Custom Curve Object Draw Function
@dks5254 wrote:
I am trying to write a class for a custom curve object that also includes custom drawing. At this phase I am still testing around and trying to become familiar with writing plugins in c++.

Here is the code:

Crash Log of Rhino
@Mat_S wrote:
I am using the rayshoot method in python on windows. After some iterations, rhino crashes.
Essentially when the code runs through a certain number of iterations it crashes. Less than this limit it works as expected. It is not running out of RAM, since I can monitor the usage and it sits around 270mb (computer has 128gb). It is not hitting an array limit (its a dict of around 900 key/value), and I checked rhino python interpreter is returning an error if it exceeds the limit (during my debugging).
When the code runs more iterations than it can (which is about 2 seconds of computation time, then on higher iteration takes 10 seconds ) and crashes, rhino just shuts off completely. There is no freezing, hanging, or windows error message, it just closes and thats it. Is there a log or way to figure out the traceback on what caused Rhino to shut off?

Socket cannot close from script
@nathancoatney wrote:
This is probably a long-shot, but I’m hoping someone here may have some advice or workaround.
I have a rhinopython script that opens a modeless eto window and a socket server on another thread. Control and communication are via two Queue.Queue(). The general idea is the window is just for display/feedback and stopping the server/script when user wants to. External programs connect a socket to the server and send messages.
Everything works fine on the first run of the script, on a fresh start of Rhino. If I stop the script, everything seems to shut down correctly…no errors or exceptions that can see. However, upon second start of the script, no clients can connect to the server.
I have tried 2 approaches for the socketry:
Using non-blocking socket.socket()
Using SocketServer.TCPServer()
results in multiple listening handles holding the socket, according to netstat -ano|findstring
results in [Errno 10048] Only one usage of each socket address (protocol/network address/port) is normally permitted, since I can’t seem to get the reuse option set to true.
Method 2 is more overhead than I want, and isn’t solving anything for me.
Charging on with method 1, I duplicated the code as much as possible in cpython and observe with netstat that the listening handle does not linger as it is in rhino. Curiously, I also observe if I wait long enough, the listening handles from rhino.exe will disappear on their own, and clients can then connect after I start the script again.
I have taken great care to .close() all client connections after receiving data, as well as the serving socket, upon exiting of the eto window (on_form_close event). The thread is join()ed after socket is closed.
I have a feeling that the lingering listening handle exists because Rhino.exe (that is the PID associated) is still running. The only other thing I can think to try is to use .net socket/thread instead of the ironpython implementations, but haven’t been able to google up any information that may suggest that will change anything.
I can send some minimal code if anyone would like to take a look.
Thanks.

Store Array of Objects in another Objects UserDictionary
@dks5254 wrote:
I am working on a Python project using rhinocommon and have stumbled on some questions. Is it possible to store an array of geometryBase objects such as curves in the UserDictionary of another object? I see that one option is Set(String, IEnumerable<Guid>) which I have tried doing. Originally I tried simply:
branch[i][0].UserDictionary.Set("Stored",curves)Which gave me an error “Multiple targets could match: Set(str, IEnumerable[ObjRef]), Set(str, bool), Set(str, IEnumerable[Guid]), …”. So I tried the following:
branch[i][0].UserDictionary.Set.Overloads[str,IEnumerable[Guid]]("Stored",curves)However now I am receiving an error “MakeGenericType on non-generic type”. And even if I get this to work I would prefer if these curves lived only in the memory and not as a manipulable object in the document.
TL:DR: How can I store a list of curves in another objects UserDictionary? If not possible, how do I at least store a list of Guids in another objects UserDictionary?
EDIT: Solved the user dictionary of Guid (was importing System.Collections.IEnumerable as IEnumerable instead of System.Collections.Generic.IEnumerable as IEnumerable (used in “.Overloads[…”). This is fine, and I am just locking and hiding the curve objects before adding their Guids to the dictionary, however hideSwap causes them to appear still, and I am looking for these objects to not be possible to interact with in any way so this is still not ideal. However found another post about converting to byte array and and then storing strings that way, is that possible for curve objects potentially as well?

Getting objects original variable name
@samlochner wrote:
Say I create a point and add it to the doc as follows:
Dim CenterPoint = new point3d(10,10,10)
Dim CenterPointID = doc.objects.addpoint(CenterPoint)Now that the point is in the doc, is there any way for me to figure out figure out what the original name of the point’s variable was (CenterPoint). I’m asking because I am adding a huge number of objects to the doc and I haven’t set the attributes to reflect their name. And I’m trying to figure out which is which.
I’m picturing a function where, from within Rhino, I pick the object in question, and somehow I’m alerted to what the original name of it’s variable was (should be CenterPoint).
Suggestions?
Thanks,
Sam
