Apply loads to load cases, RSA 2024

stefanyC6JZ7 — Mon, 07 Aug 2023 14:49:33 GMT

Hello everyone,

I am trying to use RSA 2024 with the extention Dynamo to run the following script. My objective is to get the bars loaded with the input values as the first figure on the left shows. However the python script gives me an error.

The error is "PythonEvaluator.Evaluate operation failed/ IndentationError : ('Expected an indented block',('<string>',37,5,' Uniform = []\n'))". occurs when running the script.

The Python script is also attached.

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.dll") 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 objects = IN[0] LoadCaseID = IN[1] ILRT = IN[2] LoadPX = IN[3] LoadPY = IN[4] LoadPZ = IN[5] application = RobotApplicationClass() project = application.Project structure = project.Structure labels = structure.Labels loads = structure.Cases CreatedLoads = [] case = structure.Cases.Get(LoadCaseID) simplecase = IRobotSimpleCase(case) rec = IRobotLoadRecordMngr(simplecase.Records) count = rec.Count for i in range(count+1)[::-1]: rec.Delete(i) for j in range(len(objects)): for k in range(len(objects[j])): Uniform = [] Uniform.append(rec.New(ILRT)) LoadRecord = IRobotLoadRecordLinear3D(rec.Get(Uniform[0])) LoadRecord.SetValue(0,LoadPX) LoadRecord.SetValue(1,LoadPY) LoadRecord.SetValue(2,LoadPZ[j]) LoadRecord.Objects.FromText(' '.join(str(objects[j]) for el in objects)) CreatedLoads.append(LoadRecord.UniqueID) #LoadRecord.Objects.FromText(str(objects[j][k])) application.Visible = True application.Interactive = True application.Project.ViewMngr.Refresh() OUT = objects

Could you help me to solve this issue?

Thank you beforehand for your help.

Hi all,

Identation error is gone. But now we get the com object error.

This is the result we get when we run the script with RSA2022 and dynamo 2.11

input and script view

List input part 2

code

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.dll") 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 objects = IN[0] LoadCaseID = IN[1] ILRT = IN[2] LoadPX = IN[3] LoadPY = IN[4] LoadPZ = IN[5] application = RobotApplicationClass() project = application.Project structure = project.Structure labels = structure.Labels loads = structure.Cases CreatedLoads = [] case = structure.Cases.Get(LoadCaseID) simplecase = IRobotSimpleCase(case) rec = IRobotLoadRecordMngr(simplecase.Records) count = rec.Count for i in range(count+1)[::-1]: rec.Delete(i) for j in range(len(objects)): #for k in range(len(objects[j])): Uniform = [] Uniform.append(rec.New(ILRT)) LoadRecord = IRobotLoadRecord(rec.Get(Uniform[0])) LoadRecord.SetValue(0,LoadPX) LoadRecord.SetValue(1,LoadPY) LoadRecord.SetValue(2,LoadPZ[j]) LoadRecord.Objects.FromText(' '.join(str(objects[j]) for el in objects)) #CreatedLoads.append(LoadRecord.UniqueId) #LoadRecord.Objects.FromText(str(objects[j][k])) application.Visible = True application.Interactive = True application.Project.ViewMngr.Refresh() OUT = objects

With the code above we get at line 40 the _COM object error. when using RSA2024. Could someone explain us why this is happening, both languages/settings are CPython3

Hope some of you may help us out? @cool.stuff @vise92 @Stephane.kapetanovic @JacquesGaudin

hi @1234eddie, @stefanyC6JZ7

I can't see what's in the ILRT variable and if it can match with IRobotLoadRecord.

Best Regards

It's the number 5 of the 'list 2'.

hi @1234eddie

try the loop like this and inspect the num and LoadRecord values

LoadRecord = IRobotLoadRecord for j in range(len(objects)): Uniform = [] num = rec.New(ILRT) Uniform.append(num) LoadRecord = rec.Get(num) LoadRecord.SetValue(0,LoadPX) # ...

Hi @Stephane.kapetanovic

Thank you for your answer.

We have followed your code, however the ComObject error is still happening. Please see figure bellow

Also the files are attached. Could you check them please?

JacquesGaudin — Tue, 08 Aug 2023 08:47:49 GMT

You don't need the list `Uniform` anymore. I would try this:

# Uniform = [] # Uniform.append(rec.New(ILRT)) LoadRecord = IRobotLoadRecord(rec.Create(ILRT)) LoadRecord.SetValue(0,LoadPX) LoadRecord.SetValue(1,LoadPY) LoadRecord.SetValue(2,LoadPZ[j])

Hi @JacquesGaudin,

Thank you for your reply. We changed the code, there was an error with line 8, so, first, we changed line 8 for 9 and it worked. Then, from line 38 to line 40, they are neglected, and I got a new error: "Attribute Error:' IRobotLoadRecord' has no attribute 'Create' line 41." Please see figure below.

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.dll") #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 objects = IN[0] LoadCaseID = IN[1] ILRT = IN[2] LoadPX = IN[3] LoadPY = IN[4] LoadPZ = IN[5] application = RobotApplicationClass() project = application.Project structure = project.Structure labels = structure.Labels loads = structure.Cases CreatedLoads = [] case = structure.Cases.Get(LoadCaseID) simplecase = IRobotSimpleCase(case) rec = IRobotLoadRecordMngr(simplecase.Records) count = rec.Count for i in range(count+1)[::-1]: rec.Delete(i) for j in range(len(objects)): #for k in range(len(objects[j])): #Uniform = [] #NUM = rec.New(ILRT) #Uniform.append(NUM) LoadRecord = IRobotLoadRecord(rec.Create(ILRT)) LoadRecord.SetValue(0,LoadPX) LoadRecord.SetValue(1,LoadPY) LoadRecord.SetValue(2,LoadPZ[j]) LoadRecord.Objects.FromText(' '.join(str(objects[j]) for el in objects)) #CreatedLoads.append(LoadRecord.UniqueId) #LoadRecord.Objects.FromText(str(objects[j][k])) application.Visible = True application.Interactive = True application.Project.ViewMngr.Refresh() OUT = objects

Could you please check it?

Strange the `Create` method used to be there.

What do you get if you insert the following command:

print(dir(rec))

Re: Apply loads to load cases, RSA 2024

stefanyC6JZ7 — Tue, 08 Aug 2023 10:11:51 GMT

@JacquesGaudin We changed the code as you suggested, however we get the error: " TypeError: object does not implement IRobotLoadRecord, line 41"

Could you check it please?

Re: Apply loads to load cases, RSA 2024

JacquesGaudin — Tue, 08 Aug 2023 10:16:14 GMT

That's why I use `Create` rather than `New`.

`Create` returns the load record object whereas `New` returns the index.

Did you try to ``print(dir(rec))``? It would be good to see the result of this command to check whether `Create` is still a method of IRobotLoadRecordMngr.

stefanyC6JZ7 — Tue, 08 Aug 2023 10:33:49 GMT

@JacquesGaudin

thanks for your reply,

we had to change the call a little bit. is this the list you mean?

Re: Apply loads to load cases, RSA 2024

JacquesGaudin — Tue, 08 Aug 2023 10:45:10 GMT

Shocking! 😉

It seems that `Create` was removed from IRobotLoadRecordMngr!

@gwizdzm Do you know anything about this?

Re: Apply loads to load cases, RSA 2024

1234eddie — Tue, 08 Aug 2023 15:04:28 GMT

@JacquesGaudin

Many thanks for your involvement already.

@okapawal @Rafal.Gaweda it seems like @gwizdzm is quite inactive, do you know any other members that coöperate with the structural analysis package?

Many thanks in advance

Hi @JacquesGaudin

We did some trial and error on our script. and figured out that the '.new' function does work. see the images below

creation of the load type does work. te green box line 13 is on our inputs list which does contain 4 list, in the red box is the answer and it says that it ended with 4. that's correct in my opinion. in line 44 'yellow arrow' the .new function is used and indeed in the second image you can see that there is 4 times a uniform load created. Below is the code we used.

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.dll") #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 objects = IN[0] LoadCaseID = IN[1] ILRT = IN[2] LoadPX = IN[3] LoadPY = IN[4] LoadPZ = IN[5] application = RobotApplicationClass() project = application.Project structure = project.Structure labels = structure.Labels loads = structure.Cases CreatedLoads = [] CreatedLoadstype = [] case = structure.Cases.Get(LoadCaseID) simplecase = IRobotSimpleCase(case) rec = IRobotLoadRecordMngr(simplecase.Records) #rec2 = IRobotLoadRecordLinear3D(simplecase.Records) count = rec.Count for i in range(count+1)[::-1]: #rec = simplecase.Records.Delete(i) rec.Delete(i) #CreatedLoads.append(dir(rec)) #OUT = print(dir(rec)) for j in range(len(objects)): #for k in range(len(objects[j])): Uniform = [] NUM = rec.New(ILRT) Uniform.append(NUM) CreatedLoadstype.append(dir(NUM)) LoadRecord = IRobotLoadRecord(rec.Get(Uniform[0])) CreatedLoads.append(dir(LoadRecord)) #LoadRecord = IRobotLoadRecordType(rec.New(ILRT)) #LoadRecord = IRobotLoadRecord2.(NUM) #LoadRecord = IRobotLoadRecordType(NUM) #LoadRecord.SetValue('I_URV_PX',LoadPX)) #LoadRecord.GetValue(1,LoadPY) #LoadRecord.GetValue(2,LoadPZ[j]) #LoadRecord.Objects.FromText(' '.join(str(objects[j]) for el in objects)) #CreatedLoads.append(LoadRecord.UniqueId) #LoadRecord.Objects.FromText(str(objects[j][k])) application.Visible = True application.Interactive = True application.Project.ViewMngr.Refresh() #OUT = CreatedLoads OUT = LoadRecord,CreatedLoads,Uniform,NUM,objects,LoadCaseID,ILRT,LoadPX,LoadPY,LoadPZ

With all this, we know need to figure out in which part/ where is "setvalue" now related?? Because the output of 'LoadRecord' is still a _com object.

Many thanks in advance

Re: Apply loads to load cases, RSA 2024

JacquesGaudin — Wed, 09 Aug 2023 08:33:10 GMT

@1234eddie Good to know the creation of the load record works. The `New` method is fine, it was just my preference to get the LoadRecord object returned rather than its index but the functionality is pretty much the same.

I'm not sure why `LoadRecord` doesn't have a `SetValue` method after casting to `IRobotLoadRecord`. Would you be able to share the exact error message?

Also I don't have Robot 2024 on my machine, just 2023. I would be curious to see what the API document says about IRobotLoadRecord and IRobotLoadRecordMngr. The document is usually in C:\Program files\Autodesk\Robot Structural Analysis Professional 2024\SDK.

Re: Apply loads to load cases, RSA 2024

1234eddie — Wed, 09 Aug 2023 09:18:14 GMT

@JacquesGaudin

this is the error message, don't know if this is exactly what you are looking for?

or could it be that we call "IRobotLoadRecord" with it's settings wrong?

Many thanks in advance, we really appreciate it.

Re: Apply loads to load cases, RSA 2024

JacquesGaudin — Wed, 09 Aug 2023 11:27:37 GMT

Thanks, that 's helpful.

The type cast to IRobotLoadRecord works but the `SetValue` method is missing on the object. It seems to be a similar problem with the `Create` method of `IRobotLoadRecordMngr`.

There's not much we can do to retrieve these methods if they're not exposed in the API, I think Autodesk has to fix it on their side.
