Calculation of Steel Design, CPython3

stefanyC6JZ7 — Mon, 22 Aug 2022 15:00:31 GMT

Hi all,

We are currently upgrading our scripts from IronPhyton 2 to CPhyton 3.

I am trying to get the calculations of steel in Robot with Dynamo, CPython3 version. I want to achieve a result like the figure shows.

But I get the following AttributeError : type object 'RDimServer' has no attribute 'IRDimCalcEngine' [' File "<string>", line 36, in <module>\n'].

import clr clr.AddReference('ProtoGeometry') from Autodesk.DesignScript.Geometry import * from System import Environment user = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData) sys.path.append(user+r"\Dynamo\Dynamo Core\2.11\packages\Structural Analysis for Dynamo\bin\RSA\Interop.RobotOM.d11") clr.AddReference('interop.RobotOM') #clr.AddReference(user+r"\Dynamo\Dynamo Core\2.11\packages\Structural Analysis for Dynamo\bin\RSA\Interop.RobotOM.dll") from RobotOM import * from System import Object #The inputs to this node will be stored as a list in the IN variables. objects = IN[0] #File = IN[1] #Location = IN[2] application = RobotApplicationClass() project = application.Project structure = project.Structure labels = structure.Labels application.Project.ViewMngr.Refresh() project.CalcEngine.AnalysisParams.IgnoreWarnings = True calcEngine = project.CalcEngine calcEngine.AutoGenerateModel = True calcEngine.UseStatusWindow = True calcEngine.Calculate() #project.SaveAs(Location+"\\"+ File +".rtd") #project.Save() #project.SaveAs("D:\\Werk\Robot\Dynamo files ontwikkeling\BFS-optimo learn\Modellen\test 7\Modeltest.rtd") RDMServer = IRDimServer RDMServer = application.Kernel.GetExtension("RDimServer") #RDMServer = (IRDimServerMode.I_DSM_STEEL)#werkt niet RDMServer.Mode = 1 RDmEngine = IRDimCalcEngine RDmEngine2 = RDimServer.IRDimCalcEngine #optional use it if you want to set calculation parameters by the code RDMCalpar = IRDimCalcParam RDMCalCnf = IRDimCalcConf RDMCalpar = RDmEngine.GetCalcParam() RDMCalCnf = RDimEngine.GetCalcConf() RdmStream = IRDimStream RdmStream = RDMServer.Connection.GetStream() RdmStream.Clear() RdmStream.WriteText("all") #RDMCalpar.SetObjsList(1,RdmStream) RDMCalpar.SetObjsList(IRDimCalcParamVerifType.I_DCPVT_MEMBERS_VERIF, RdmStream) RDMCalpar.SetLimitState(IRDimCalcParamLimitStateType.I_DCPLST_ULTIMATE,1) RdmStream.Clear() RdmStream.WriteText("1to7") RDMCalpar.SetLoadsList(RdmStream) RDmEngine.Solve(RdmStream) #RDmEngine.Solve(None) RdmAllResObjType = IRDimAllResObjectType RdmAllRes = IRDimAllRes #RdmDetRes = IRDimDetailedRes RdmAllRes = RDmEngine.Results() RdmAllResObjType = 1 #RdmAllResObjType = RdmAllRes.ObjectsType(IRDimAllResObjectType.I_DAROT_VERIFIED_MEMBER) ObjCnt = RdmAllRes.ObjectsCount RDmRetValue = IRDimMembCalcRetValue RDmDetRes = IRDimDetailedRes RDmDetRes = RdmAllRes.Get("1") #RDmRetRes = RDmEngine.Results(1) #RdmDetRes = RdmAllRes.Get(1) Case = RDmDetRes.GovernCaseName Ratio = RDmDetRes.Ratio RdmCodeRes = object RdmCodeRes = RDmDetRes.CodeResults Nbyrd = RdmCodeRes.BuckStrenNbyrd #OUT = OUT = RdmAllRes, RdmStream, Case, Ratio, Nbyrd #OUT = "goed bezig"

Could you help me to review what is wrong with the code?

Thank you in advance.

Best Regard,

Hi all,

I have seen your names in similar topics, maybe one of you can help me out?

I don't think you need this line at all. Maybe try to comment it.

RDmEngine2 = RDimServer.IRDimCalcEngine

The error says that the type `RDimServer` doesn't have any attribute named IRDimCalcEngine which is expected according to the API doc.

Did you mean this?

RDmEngine2 = IRDimCalcEngine

But even then RDmEngine2 is not used elsewhere in the script...

Hi @JacquesGaudin.,

Thank you for your answer. You are right, it is not necessary the RDmEngine2, so I have commented those lines, to continue with the script. However, now I am stuck with line 15, I get the following error, "No method matches given arguments for WriteText: ()"

RDMServer.Mode = 1 RDmEngine = IRDimCalcEngine #RDmEngine2 = RDimServer.IRDimCalcEngine #RDmEngine2 = IRDimCalcEngine #optional use it if you want to set calculation parameters by the code RDMCalpar = IRDimCalcParam RDMCalCnf = IRDimCalcConf RDMCalpar = RDmEngine.GetCalcParam RDimCalcParam = RDmEngine.SetCalcConf RDMCalCnf = RDmEngine.GetCalcConf #RdmStream = IRDimServer.Connection.GetStream #RDmStream = IRDimMembDefData(IRDimStream) RDmStream = IRDimStream RdmStream.Clear RdmStream.WriteText("all") I_DCPVT_MEMBERS_VERIF = 1

Could you help me to check why it is not working?.

I was checking the RobotAPI documentation of steel and it says that WriteText is part of the IRDimStream interface.

Thank you in advance.

Best regards,

Stefany

You have some typos here. Could you please fix them before we have a look at what is going on?

Hi @JacquesGaudin,

Thank you for your reply. Now, I corrected the typos of the script. However, I still get the following error:

"TypeError : not enough arguments [' File "<string>", line 48, in <module>\n']", please see figure below.

There is a problem in your code with the definition of RDmStream. It assigns the type to the variable rather than an instance of the type.

In Python the methods of a class are usually called with the instance itself as a first argument, but if you call the method from the type, then the instance argument is not there and that messes up the method call.

I changed your code to the following. I hope it works.

RDmStream = IRDimStream(RDMServer.Connection.GetStream()) # Setting RDmStream to an instance of IRDim Stream

Hi @JacquesGaudin,

Thank you for your reply. I have changed the code as you suggested, but now I get the following error:

"AttributeError : '__ComObject' object has no attribute 'Connection' [' File "<string>", line 38, in <module>\n']".

I have tried to change it into two different ways but I still do not get the script working properly.

RDmStream = IRDimStream(IRDimServer.Connection.GetStream())

First I changed line 38, but I get the following error:

" instance property must be accessed through a class instance [' File "<string>", line 38, in <module>\n']"

RDmStream = IRDimStream(IRDimConnection.GetStream())

Then, I changed same line, but the following error appears:

"Warning: TypeError : not enough arguments [' File "<string>", line 38, in <module>\n']"

Could you help me to check what is going wrong with the script?

Thank you in advance.

Best regards,

Stefany

The error message says that `RDmServer` is a plain COM object and doesn't have any attribute named Connection.

"AttributeError : '__ComObject' object has no attribute 'Connection' [' File "<string>", line 38, in <module>\n']".

So, as previously explianed the fix is to cast to the expected type, in this instance IRDimServer:

RDMServer = IRDimServer(application.Kernel.GetExtension("RDimServer"))

Most of the errors you encounter are of this type. I'm going to be away for two weeks so try and understand how to fix them by yourself. If there is something you don't understand, I can answer your question until tonight.

The revised script:

Hi all,

Thank you for your reply. I could develop the code a bit further, and I got two results, the Ratio and Case Name. Please see the figure below.

The problem is that I also want the results from Eurocode3, for example, as red box shows in the next figure the Ny,b,Rd. But I get the following error: "AttributeError : '__ComObject' object has no attribute 'BuckStrenNbyrd'".

Then, I have been trying to call the attribute as line 55 shows:

RDmCodeRes = IRDimCodeResEC3(structure(RDmCodeRes(IRDimDetailedRes.CodeResults.BuckStrenNbyrd("1"))))

But, it is not working and I get the following error :" instance property must be accessed through a class instance [' File "<string>", line 55, in <module>\n']"

Could someone help me to check what is missing in the code? To get through the comObject and Class instance.

Thank you in advance.

Hi all,

Question is still goiing on.

Maybe @LionelDallenne @vise92 @Anonymous @milczarekuba @lukasz_koc1 or others know how to get this one?

Hi @JacquesGaudin,

Thank you for your reply. We have solved the script, it is working perfectly. Thank you very much for your help solving the issues and with help from dynamo forum.
