Robot load case labels(dynamo, API, Python)

Hi @tuska.marci @Rafal.Gaweda and others.

Im trying to use dynamo to create loadcases and combinations in robot,(normally a time consuming proces). i got this working (see this link ). but the problem i have now is that the loadcase label is the same as the loadcase name. In this topic it was solved, but i can't get it working.

Hopefully someone can tell me what i should change??

This is the error i get when running te script. (the loadcase is well created)

This is the python script

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.
LoadCaseName = IN[0]
LoadCaseNumber = IN[1]
LoadCaseLabel = IN[2]
application = RobotApplicationClass()
project = application.Project
structure = project.Structure
labels = structure.Labels
loads = structure.Cases
#output
Caseeigengewicht = structure.Cases.CreateSimple(LoadCaseNumber,LoadCaseName,IRobotCaseNature.I_CN_PERMANENT,IRobotCaseAnalizeType.I_CAT_STATIC_LINEAR)

label = labels.Create(IRobotSimpleCase.Label(1,"EG"))
labels.Store(label)
structure.Cases.SetLabel(1,IRobotSimpleCase.Label,"EG")

Caseeigengewicht.Records.New(IRobotLoadRecordType.I_LRT_DEAD)
LoadRecord = Caseeigengewicht.Records.Get(1)
LoadRecord.SetValue(IRobotDeadRecordValues.I_DRV_Z,-1)
LoadRecord.SetValue(IRobotDeadRecordValues.I_DRV_ENTIRE_STRUCTURE,True)
OUT = LoadCaseNumber

This is the loadcase label which should be “EG”

corresponding chapters in robot API documentation

as attachment the dynamo file(you can run it with just an empty robot file)

Thanks in advance,

Gr Edward.

@Artur.Kosakowski @Rafacascudo @Romanich

Can someone of you help me with this guys?

I would really love to solve this problem. (i want to solve because i can't sent it to a client, with te wrong labels.)

Thanks in advance.

Gr Edward

Hi @1234eddie

I hope You meant this (label is not the case name).

(VBA example but it should be clear enough to understand)

Hi @1234eddie

Short explanation: Labels created \ got by Labels server or by HasLabel \ SetLabel are objects like bar Section, Support, Releases, Materials and so on.

This label (misleading name in this case) is just a string = text.

Many thanks @Rafal.Gaweda

Your photo and explanation made it clear for me.

I have attached the corrected dynamo file.
