API Robot Python - Panel

[polylouis]

Hello everyone,

I tried to do add new label for thicknness panel :

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

thData=IRobotThicknessData

thData = label.Data

thData.MaterialName = "S235"

thData.ThicknessType = IRobotThicknessType.I_TT_HOMOGENEOUS

homo = IRobotThicknessHomoData

homo = thData.Data

homo.Thickconst = "0,025"

labels.Store(label)

same think on my python script but I have the following error : 

I have the following error : 

thData = label.Data
AttributeError: '__ComObject' object has no attribute 'Data'

Do you have a solution to fix this problem ?

Thank you in advance,

Louis

hi @polylouis 

how did you define the type label, provide previous lines.

Best regards

Hi,

Here is the definition : 

import clr

ref = clr.AddReference(

    "C:\Program Files\Autodesk\Autodesk Robot Structural Analysis Professional 2021\System\Exe\Interop.RobotOM.dll")

from RobotOM import *

from System import *

from System import Environment

app = RobotApplicationClass()

project = app.Project

project.New(IRobotProjectType.I_PT_SHELL)

labels = structure.Labels

Regards,

Louis

hi @polylouis 

As explained, your problem is probably due to not converting the label variable to a RobotLabel type, reason why you cannot access to datas.

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

Don't do implicit casting with robot API in python try setting explicitly your variable.

Hi Stephane,

Thnak you for your reply !

I have another error: 

label = IRobotLabel(labels.Create(IRobotLabelType.I_LT_PANEL_THICKNESS,"E120"))

thData=IRobotThicknessData

thData = label.Data

thData.MaterialName = "C30/37"

thData.ThicknessType = IRobotThicknessType.I_TT_HOMOGENEOUS

homo = IRobotThicknessHomoData

homo = thData.Data

homo.Thickconst = "120"

labels.Store(label)

File "testrobot.py", line 82, in <module>
homo = thData.Data
AttributeError: '__ComObject' object has no attribute 'Data'

Thank a lot for your support,

Louis

hi @polylouis 

same issue, label.data and thData.Data returns dynamics vars so cast is necessary. 

thData = IRobotThicknessData(label.Data)
[...]
homo = IRobotThicknessHomoData(thData.Data)

To understand, try to find topics on boxing/unboxing ___.data returns on multiple types and all are specific that is equal to using same object but recept it in different container declining himself into parts also.

Thanks a lot for your help. It works ! 

I would like talk about other subject. On my panel I have a to add several node forces (for example 4) 

I did like following example : 

case_number = cases.FreeNumber

dl= cases.CreateSimple(case_number, "n1", IRobotCaseNature.I_CN_EXPLOATATION, IRobotCaseAnalizeType.I_CAT_STATIC_LINEAR)

dl_record = dl.Records.Create(IRobotLoadRecordType.I_LRT_NODE_FORCE)

dl_record = IRobotLoadRecord(dl_record)

dl_record.Objects.AddOne(node1)  # select nodes

dl_record.SetValue(IRobotNodeForceRecordValues.I_NFRV_FZ,XXX)

dl_record.SetValue(IRobotNodeForceRecordValues.I_NFRV_FX,XXX)

The only solution I find is to do that for each nodes (ie x4) and combine in a "load combinaison" after 

Do you have any ideas to be more efficient about that ?

Thank you in advance,

Louis

hi @polylouis 

first close the topic and accept one or several solutions as accepted.

Second create a new thread with new questions in this category.

Hello everyone !

Alike the creation of label for thickness label I would like to do the same for Reinforcement data.

I have a problem about "Minimum Reinforcement" label :

label_slab = IRobotLabel(labels.Create(IRobotLabelType.I_LT_PANEL_REINFORCEMENT, "REINF_massif2"))

rnfData=IRConcrReinforceData(label_slab.Data)

rnfData.Cover_Bot=XXXX

rnfData.Cover_Up=YYYY

rnfData.SetMainDirection(IRConcrReinforceDirection.I_CRD_ALONG_X,1,1,1)

rnfData.MinimumReinf=IRConcrMinimumReinforcementType.I_CMRT_NONE

All is good (no error given) but the last line is not taken into account..

Do you have any ideas to fix this problem ?

Thank you in advance,

Louis

hi @polylouis 

IRConcrReinforceData interface has no property IRConcrReinforceData

IRConcrReinforceData interface has no property MinimumReinf. Sorry
