API RDm engine solver error

Hi all,

I'm currently working on a script to do the steel verification using the API. Im working with this inside a python schript.

I got some good examples(excel vba) but my script won't work. This is the error i get:

this is what is written inside the API SDK document of the steel design(written for C#)

This is how i have written it in my code:

Line 48 RDmEngine.Solve()

I guess that i'm missing the part which says 'Nothing' but dont know how to write it/how to add it.

This is the full code i'm using.

import clr clr.AddReference('ProtoGeometry') from Autodesk.DesignScript.Geometry import * from System import Environment user = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData) clr.AddReferenceToFileAndPath(user +r"\Dynamo\Dynamo Core\1.3\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 RDmEngine = RDMServer.CalculEngine #optional use it if you want to set calculation parameters by the code RDMCalpar = IRDimCalcParam RDMCalCnf = IRDimCalcConf RDMCalpar = RDmEngine.GetCalcParam() RDMCalCnf = RDmEngine.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("1to6") RDMCalpar.SetLoadsList(RdmStream) RDmEngine.Solve() RdmAllResObjType = IRDimAllResObjectType RdmAllRes = IRDimAllRes RdmDetRes = IRDimDetailedRes RdmAllRes = RDmEngine.Results() RdmAllResObjType = 1 #RdmAllResObjType = RdmAllRes.ObjectsType(IRDimAllResObjectType.I_DAROT_VERIFIED_MEMBER) #ObjCnt = RdmAllRes.ObjectsCount UsrNo = RdmAllRes.ObjectsUsrNo(1) RDmRetValue = IRDimMembCalcRetValue RDmRetRes = IRDimDetailedRes RdmDetRes = RdmAllRes.Get(1) Case = RdmDetRes.GovernCaseName Ratio = RdmDetRes.Ratio OUT = RdmAllRes, Case, Ratio #OUT = "goed bezig"

Maybe @Rafal.Gaweda or others know a solution?

All files are attached.

Thanks in advance

@JacquesGaudin @Anonymous @Anonymous @klavs @chjpcoi

I have seen your names in some related topics to API.

I hope someone of you recognise my problem and maybe how to solve it?

or know others who can.

tanks in advance

I would try this:

RDmEngine.Solve(None)

@JacquesGaudin thanks for your reply.

i tried your option, but it's gives the same error.

But i found the solution(don't know why it's working).

RDmEngine.Solve(RdmStream)

with this it's running and i get the results i want.

File is attached.
