[EC8 & Python code]

xroguiez — Wed, 14 Dec 2022 20:39:44 GMT

Hello
I am trying to transform VBA code into Python from the example provided here: https://forums.autodesk.com/t5/robot-structural-analysis-forum/api-seismic-case-definition/m-p/3357839/highlight/true#M3137
But I can't access the GetAnalysisParams() methods :

caseEdX = structure.Cases.CreateSimple(6, "Ed+X", RobotOM.IRobotCaseNature.I_CN_SEISMIC , RobotOM.IRobotCaseAnalizeType.I_CAT_DYNAMIC_SEISMIC) num_EdX1 = caseEdX.GetSeismicCode #is empty #doesn't work num_EdX1 = caseEdX.Records.New(RobotOM.IRobotSeismicAnalysis_EC8_General_Params) #a validate EC8params = caseEdX.GetAnalysisParams #is empty too

Can someone help me?
Thanks for any help

Hi @xroguiez

You must declare your variable types

Hello

I agree with you but how to do it (in Python) ? I couldn't do it

Thanks

> To declare a variable

Variable = Type_of_Variable (Class / Interface)

Example:

thData = IRobotThicknessData

> To Cast

Variable_0 = Type_of_Variable(Variable_1)

b = 125.3
print(int(b))
Output
125

Example:

label = RobotLabel(labels.Create(IRobotLabelType.I_LT_PANEL_THICKNESS,"25mm"))

therefore, you must declare the types of variables when necessary and check the output types of the functions according to the variables types to perform the casts

Best Regards

Thank you for all your advice.

I took the example in the link on the first 4 lines

VBA Source :

Dim ECParams As RobotSeismicAnalysis_EC8_General_Params Set EQLoad = Robapp.Project.Structure.Cases.CreateSimple(200, "EarthQuake+X", I_CN_SEISMIC, I_CAT_DYNAMIC_SEISMIC) Set ECParams = EQLoad.GetAnalysisParams ECParams.Ag = Foglio2.Range("F9")

And then a partial version of Python transcription that works perfectly:

ECParams = RobotOM.RobotSeismicAnalysis_EC8_General_Params ModalParams = RobotOM.RobotModalAnalysisParams #I'm using different namespaces, but it's the same syntax EQLoad = structure.Cases.CreateSimple(6, "Ed+X", RobotOM.IRobotCaseNature.I_CN_SEISMIC , RobotOM.IRobotCaseAnalizeType.I_CAT_DYNAMIC_SEISMIC)

The console proof, :

>>> dir(ECParams) ['Ag', 'B', 'BehaviorFactor', 'Direction', 'DirectionType', 'ExcitationDir', 'Filter', 'ResidualMode', 'S', 'Spectrum', 'Tb', 'Tc', 'Td', '__doc__', '__repr__'] dir(EQLoad) ['AnalizeType', 'CreateObjRef', 'Equals', 'GetAnalysisParams', 'GetHashCode', 'GetLifetimeService', 'GetSeismicCode', 'GetType', 'InitializeLifetimeService', 'IsAuxiliary', 'MainMode', 'MemberwiseClone', 'ModesCount', 'Name', 'Nature', 'NatureName', 'Number', 'Records', 'ReferenceEquals', 'SetAnalysisParams', 'SetNatureExt', 'TimeStepCount', 'ToString', 'Type', 'UniqueId', 'UserId', '__class__', '__delattr__', '__doc__', '__format__', '__getattribute__', '__hash__', '__init__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__', 'label']

But the next point is completely blocking, i don't understand how to cast :, in this attempt, the intial variable is erasing

#### here is my main cast problem... ECParams = EQLoad.GetAnalysisParams >>> ECParams = EQLoad.GetAnalysisParams >>> dir(ECParams) ['Equals', 'GetHashCode', 'GetType', 'MemberwiseClone', 'ReferenceEquals', 'ToString', '__class__', '__delattr__', '__doc__', '__format__', '__getattribute__', '__hash__', '__init__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__']

Another clumsy attempt :

>>> EQLoad.SetAnalysisParams(ECParams) Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: Le cast spécifié n'est pas valide. >>> EQLoad.SetAnalysisParams(ECParams()) Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: Cannot create instances of RobotSeismicAnalysis_EC8_General_Params because it is abstract >>> ECParams.Ag = 1. Traceback (most recent call last): File "<stdin>", line 1, in <module> AttributeError: static property 'Ag' of 'IRobotSeismicAnalysis_EC8_General_Params' can only be assigned to through a type, not an instance

To be honest, i don't know in this how to cast it ? Could you help me ?

Thanks for all

How did you define EQLoad ? EQLoad = RobotSimpleCase ?

Re: [EC8 & Python code]

xroguiez — Thu, 15 Dec 2022 14:17:02 GMT

Hi again

Anothers attempts of casting :

>>> ECParams = RobotOM.IRobotSeismicAnalysis_EC_8_General_Params(caseEdX.GetAnalysis()) Traceback (most recent call last): File "<stdin>", line 1, in <module> AttributeError: attribute 'IRobotSeismicAnalysis_EC_8_General_Params' of 'namespace#' object is read-only >>> ECParams = RobotOM.RobotSeismicAnalysis_EC_8_General_Params(caseEdX.GetAnalysis) Traceback (most recent call last): File "<stdin>", line 1, in <module> AttributeError: attribute 'RobotSeismicAnalysis_EC_8_General_Params' of 'namespace#' object is read-only

The thing i don't really understand is the main difference between the two path... for the modal load, it's works :

caseMod = loads.CreateSimple(5, "Modale", RobotOM.IRobotCaseNature.I_CN_EXPLOATATION , RobotOM.IRobotCaseAnalizeType.I_CAT_DYNAMIC_MODAL) num_Mod1 = caseMod.Records.New(RobotOM.IRobotLoadRecordType.I_LRT_SPECTRUM_VALUE) #a valider #loadRec = caseMod.Records.Get(num_Mod) #pas utile ici on l'applique au projet modParams = caseMod.GetAnalysisParams() modParams.Mode = RobotOM.IRobotModalAnalysisMode.I_MAM_MODAL modParams.ModesCount = 50 modParams.Damping = 5e-2 ... caseMod.SetAnalysisParams(modParams)

These commands worked in Robot for the modal analysis and not for the seismic analysis

Hello

Like this ?

EQLoad = structure.Cases.CreateSimple(6, "Ed+X", RobotOM.IRobotCaseNature.I_CN_SEISMIC , RobotOM.IRobotCaseAnalizeType.I_CAT_DYNAMIC_SEISMIC)

Is it right ?

I've used the following shortcuts

Re: [EC8 & Python code]

Stephane.kapetanovic — Thu, 15 Dec 2022 14:44:51 GMT

Before answer to other post

Code fail ↓

ECParams = EQLoad.GetAnalysisParams

3 possible reasons :

- EcParams not defined as IRobotSeismicAnalysis_EC_8_General_Params type

- EqLoad not defined as a RobotSimpleCase type

EQLoad = RobotSimpleCase EQLoad = structure.Cases.CreateSimple(6, "Ed+X", RobotOM.IRobotCaseNature.I_CN_SEISMIC , RobotOM.IRobotCaseAnalizeType.I_CAT_DYNAMIC_SEISMIC)

- Try also

ECParams = EQLoad.GetAnalysisParams()

try to set preferences by SetActiveCode function as explain by cris.bac

there is also a remarks by Rafal Gaweda in your link

aaa = RCase.GetSeismicCode ' this is check only line, for EC codes there is no name returned here

'RobotSeismicAnalysis_EC_8_Params refers to ENV 1998-1-1:1994 DAN francaise, which is currently unused - if you are interested I can tell you how to enable this unused code

Hello

Thanks again for your help

If I understand correctly for the first point, it works for me ?

>>> ECParams = RobotOM.RobotSeismicAnalysis_EC8_General_Params

- EcParams not defined as IRobotSeismicAnalysis_EC_8_General_Params type, it seems to be right ?

>>> dir(ECParams) ['Ag', 'B', 'BehaviorFactor', 'Direction', 'DirectionType', 'ExcitationDir', 'Filter', 'ResidualMode', 'S', 'Spectrum', 'Tb', 'Tc', 'Td', '__doc__', '__repr__']

- EqLoad not defined as a RobotSimpleCase type, same conclusion ?

>>> EQLoad = RobotOM.RobotSimpleCase >>> dir(EQLoad) ['AnalizeType', 'CreateObjRef', 'Equals', 'GetAnalysisParams', 'GetHashCode', 'GetLifetimeService', 'GetSeismicCode', 'GetType', 'InitializeLifetimeService', 'IsAuxiliary', 'MainMode', 'MemberwiseClone', 'ModesCount', 'Name', 'Nature', 'NatureName', 'Number', 'Records', 'ReferenceEquals', 'SetAnalysisParams', 'SetNatureExt', 'TimeStepCount', 'ToString', 'Type', 'UniqueId', 'UserId', '__class__', '__delattr__', '__doc__', '__format__', '__getattribute__', '__hash__', '__init__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__', 'label'] >>> EQLoad = structure.Cases.CreateSimple(inumC, "Ed+X", ... RobotOM.IRobotCaseNature.I_CN_SEISMIC , ... RobotOM.IRobotCaseAnalizeType.I_CAT_DYNAMIC_SEISMIC) >>> dir(EQLoad) ['AnalizeType', 'CreateObjRef', 'Equals', 'GetAnalysisParams', 'GetHashCode', 'GetLifetimeService', 'GetSeismicCode', 'GetType', 'InitializeLifetimeService', 'IsAuxiliary', 'MainMode', 'MemberwiseClone', 'ModesCount', 'Name', 'Nature', 'NatureName', 'Number', 'Records', 'ReferenceEquals', 'SetAnalysisParams', 'SetNatureExt', 'TimeStepCount', 'ToString', 'Type', 'UniqueId', 'UserId', '__class__', '__delattr__', '__doc__', '__format__', '__getattribute__', '__hash__', '__init__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__', 'label']

-Try Also

Attempt 1 :the structure of ECParams has been deleted

>>> ECParams = EQLoad.GetAnalysisParams >>> dir(ECParams) ['Equals', 'GetHashCode', 'GetType', 'MemberwiseClone', 'ReferenceEquals', 'ToString', '__class__', '__delattr__', '__doc__', '__format__', '__getattribute__', '__hash__', '__init__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__']

Attempt 2 :the structure of ECParams has also been deleted

>>> ECParams = RobotOM.RobotSeismicAnalysis_EC8_General_Params >>> ECParams = EQLoad.GetAnalysisParams() >>> dir(ECParams) ['Equals', 'GetHashCode', 'GetType', 'MemberwiseClone', 'ReferenceEquals', 'ToString', '__class__', '__delattr__', '__doc__', '__format__', '__getattribute__', '__hash__', '__init__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__']

Attempt 3 : the structure of ECParams has also been deleted

>>> ECParams = RobotOM.RobotSeismicAnalysis_EC8_General_Params >>> aaa = EQLoad.GetSeismicCode >>> ECParams = EQLoad.GetAnalysisParams() >>> dir(ECParams) ['Equals', 'GetHashCode', 'GetType', 'MemberwiseClone', 'ReferenceEquals', 'ToString', '__class__', '__delattr__', '__doc__', '__format__', '__getattribute__', '__hash__', '__init__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__']

Is that works ?

could you write the correct integral sequence ?

Attempt 1, 2, 3 not working ?

Re: [EC8 & Python code]

xroguiez — Thu, 15 Dec 2022 15:30:59 GMT

Hello

Sorry it doesn't works.

But what do you mean with the integral sequence ? I've posted all the code and the console return

yes all code in one thread please to resume because it's hard to follow for @JacquesGaudin, @cool.stuff, @1234eddie, @Rafal.Gaweda, @napooil.

Is this conclusion still true? with Python ?

Hello

Sorry for this stream of unstructured information. I put everything in a single script ECM.txt (extension is not accepted). Is it ok ?

I'm running the script in IronPython2.7.12 and with Robot 2023. Do you have a solution to set the seismic parameters ?

Thanks for all

Xavier

Re: [EC8 & Python code]

JacquesGaudin — Fri, 16 Dec 2022 01:19:18 GMT

With the line below, you can make sure that you are using the right default:

Robapp.Project.Preferences.SetActiveCode(I_CT_SEISMIC_LOADS, "EN 1998-1:2004/A1:2013-General")

The type of seismic params depends on this setting. If you put this line before defining the seismic load case, you should get the correct type of params.

Note: In Python, you need the brackets to call a function. Without brackets, you are referring to the function / method object.

Re: [EC8 & Python code]

Stephane.kapetanovic — Wed, 23 Jul 2025 10:29:55 GMT

To obtain codes numbers and names

Preferences = RobotOM.RobotProjectPreferences Preferences = robApp.Project.Preferences #Preferences.SetActiveCodeNumber(RobotOM.IRobotCodeType.I_CT_SEISMIC_LOADS, 000) #Preferences.SetActiveCode(RobotOM.IRobotCodeType.I_CT_SEISMIC_LOADS, "XXX") CodeNumber = Preferences.GetActiveCodeNumber(RobotOM.IRobotCodeType.I_CT_SEISMIC_LOADS) Code = Preferences.GetActiveCode(RobotOM.IRobotCodeType.I_CT_SEISMIC_LOADS)

Table (to be continued) to match seismic codes and Params
