Help to connect to the Robot COM, what to write here where the question marks?

app = System.Runtime.InteropServices.Marshal.GetActiveObject(???)

Hi @Anonymous

Help to connect to the Robot COM, what to write here where the question marks?
app = System.Runtime.InteropServices.Marshal.GetActiveObject(???)
“Robot.Application”

Here is a sample code which I hope should create a node label using IronPython

import clr

# add Robot Structural Analysis API reference

clr.AddReferenceToFileAndPath(path to interop.RobotOM.dll")

# add needed import to be able to use Robot Structural Analysis objects

from RobotOM import *

from System import Object

# Connect to the running instance of Robot Structural Analysis

application = RobotApplicationClass()

# Get a reference of the current project

project = application.Project

# Get a reference of the current model

structure = project.Structure

# Get a reference of the label server

labels = structure.Labels

nodeSupportName = ”testName”

# create a new label of type support node with the name

out = labels.Create(IRobotLabelType.I_LT_NODE_SUPPORT, nodeSupportName)

# assign the node support definition to the Robot Structural Analysis object

out.Data.UX = false

out.Data.UY = false

out.Data.UZ = false

out.Data.RX = false

out.Data.RY = false

out.Data.RZ = false

# store the new created label in the open document

labels.Store(out)

I hope this helps.

Don`t work

import System
app = System.Runtime.InteropServices.Marshal.GetActiveObject(“Robot.Application”)

print app

Traceback (most recent call last):
File "I:\PythonScripts\WORK\0022 RobotVariants.py", line 6, in <module>

But this is not a problem, because you showed me how to connect to the open ROBOT project. Thank you very much!

My first Python script for Robot

import clr
# add Robot Structural Analysis API reference
clr.AddReferenceToFileAndPath("c:/Program Files/Autodesk/Autodesk Robot Structural Analysis Professional 2016/System/Exe/Interop.RobotOM.dll")
# add needed import to be able to use Robot Structural Analysis objects
from RobotOM import *
# Connect to the running instance of Robot Structural Analysis
Robapp = RobotApplicationClass()
# Get a reference of the current project
Robproj = Robapp.Project
# Get a reference of the current model
rStruct = Robproj.Structure
n1 = rStruct.Nodes.FreeNumber
rStruct.Nodes.Create(n1,0.0,0.0,0.0)
for i in range(5):
	nn = rStruct.Nodes.FreeNumber
	rStruct.Nodes.Create(nn,5.0,0.40*i,0.0)
	nb = rStruct.bars.FreeNumber
	rStruct.bars.Create(nb, n1, nn)

@Anonymous Is this working? I'm getting the following error .please comment

clr.AddReferenceToFileAndPath('C:\Program Files\Autodesk\Robot Structural Analysis Professional 2023\Exe\Interop.RobotOM.dll') AttributeError: module 'clr' has no attribute 'AddReferenceToFileAndPath'

There seems to be multiple clr modules and it could be, that you aren't using the correct module. Have you tried the following:

pip uninstall clr pip install pythonnet

Then import clr as you have been (strange, I know). Using the clr from pip install clr and printing the directories:

print(dir(clr)) ['StyleBuilder', '__builtins__', '__cached__', '__doc__', '__file__', '__loader__', '__module__', '__name__', '__package__', '__path__', '__spec__', '_styles', 'black', 'blue', 'bold', 'cyan', 'dim', 'green', 'hidden', 'inverse', 'italic', 'key', 'light_black', 'light_blue', 'light_cyan', 'light_green', 'light_magenta', 'light_red', 'light_white', 'light_yellow', 'magenta', 'on_black', 'on_blue', 'on_cyan', 'on_green', 'on_light_black', 'on_light_blue', 'on_light_cyan', 'on_light_green', 'on_light_magenta', 'on_light_red', 'on_light_white', 'on_light_yellow', 'on_magenta', 'on_red', 'on_white', 'on_yellow', 'red', 'strikethrough', 'style_builder', 'sys', 'underline', 'value', 'white', 'yellow']

Then uninstalling clr and installing pythonnet:

import clr print(dir(clr)) ['AddReference', 'FindAssembly', 'GetClrType', 'ListAssemblies', '__class__', '__doc__', '__file__', '__loader__', '__name__', '__package__', '__spec__', '__version__', '_add_pending_namespaces', '_available_namespaces', '_extras', '_load_clr_module', 'clrmethod', 'clrproperty', 'getPreload', 'loader', 'setPreload']

It seems the function name has changed to AddReference(). However, this should work.

Let me know!

How is this library being called in Python? I don't know of the System.Runtime. ... in Python? What library / module is that? 🙂
