JointOrigin rename

[MichaelT_123]

Hi TF360 and others in the know,

Are there any restrictions put on the naming convention of JointOrigin?

The simple code (ran in DM mode):

jointOrigin.name = newName

produces:

  File "C:/Users/MichaelT/AppData/Local/Autodesk/webdeploy/production/XXX/Api/Python/packages\adsk\fusion.py", line 20405, in _set_name

    return _fusion.JointOrigin__set_name(self, value)

RuntimeError: 2 : InternalValidationError : RequestProcessor::renameObject(this, jointOrigin->asset(), value)

Hi Michael,

Is the component owning the Joint Origin in question an XRef Component?

If possible, can you please share the model and the script you are using.

Hi @MichaelT_123 .

I changed only this run function and executed it.

def run(context):
    try:

        _app = adsk.core.Application.get()
        _ui = _app.userInterface

        # create document
        _app.documents.add(adsk.core.DocumentTypes.FusionDesignDocumentType)
        des :adsk.fusion.Design = _app.activeProduct
        root :adsk.fusion.Component = des.rootComponent

        # --- try root ---
        # create box
        box = createBox(root, adsk.core.Point3D.create(0.0, 0.0, 0.0))

        # create jointOrigin
        jointOrigins = createJointOriginList(box, root)

        # rename jointOrigin
        for idx, jo in enumerate(jointOrigins):
            jo.name = '{}_{}_{}'.format(root.name, box.name, idx)


        # --- try occurrence ---
        # create occurrence
        matZero = adsk.core.Matrix3D.create()
        occ :adsk.fusion.Occurrence = root.occurrences.addNewComponent(matZero)

        # create box
        box = createBox(occ.component, adsk.core.Point3D.create(20.0, 0.0, 0.0))

        # create jointOrigin
        jointOrigins = createJointOriginList(box, occ.component)

        # rename jointOrigin
        for idx, jo in enumerate(jointOrigins):
            jo.name = '{}_{}_{}'.format(occ.component.name, box.name, idx)
        

        # finish
        _ui.messageBox('Done')
        
    except:
        if _ui:
            _ui.messageBox('Failed:\n{}'.format(traceback.format_exc()))

It was renamed without any problems.

Hi Fellows,

Thank you for reaching to help. I have found the problems. In fact, I found two of them.

The clue is in the sentence I wrote describing the problem. It is 'DM'.

I don't know if JointsOrigin related portion of F360 software is still the unfinished project, or it is closed and fully functional.

The point I want to make is that many groups of F360 elements can be targeted both in both parametric and direct modelling modes. 

It seems that JointOrigins can be created only in parametric mode. As I mentioned when creating jointOrigin, I was in DM mode. The strange thing is that the system allowed me to instantiate it. I could see it on the screen, rename it through UI, etc. It was, however, not valid F360 object, was dangling somewhere in a model structure. A document with such malformed entity crashed the whole F360 software on exit or on save,  perhaps due to a memory violation.

So, there are two problems:

- the first belongs to TF360, by allowing to create illegal jointOrigin object

- the second is obviously my stupidity, and it hurts 😫 !!!!

Regards

MichaelT

PS. If my diagnosis is correct and TF360 has some compassion ( I believe it has) it would be an excellent case to extend it by correcting the first problem and, in this way potentially saving another F360 user from deprecating himself.

HI @MichaelT_123 

Joint Origins are supported in Direct Modeling (DM) mode. Could you please share a screencast / video of the issue you are seeing in DM using UI?

Also regarding API issue you are seeing, it will be really helpful if you can share the design file and the API script, so that we can take a closer look at the problem.

Thanks

Hi, Mr Sail.V.B.

 Unfortunately, I can't supply the script nor the design.

The problem could be replicated (or not) by creating jointOrgin in two ways:

- with baseFeature inactive

- with baseFeture active

The point of failure related to the issue is specified in my previous post.

Additionally, related error reports, with memory dumps and other valuable info might help to trace the problem.

@MichaelT_123 .

I was able to reproduce it. Modifying the run function like this will result in an error.

def run(context):
    try:
        global _app, _ui
        _app = adsk.core.Application.get()
        _ui = _app.userInterface

        # create document
        _app.documents.add(adsk.core.DocumentTypes.FusionDesignDocumentType)
        des :adsk.fusion.Design = _app.activeProduct
        des.designType = adsk.fusion.DesignTypes.ParametricDesignType
        root :adsk.fusion.Component = des.rootComponent

        # --- try root ---
        # create box
        box = createBox(root, adsk.core.Point3D.create(0.0, 0.0, 0.0))

        # create jointOrigin
        jointOrigins = createJointOriginList(box, root)

        # Design mode change
        des.designType = adsk.fusion.DesignTypes.DirectDesignType

        # rename jointOrigin - error!!
        for idx, jo in enumerate(jointOrigins):
            jo.name = '{}_{}_{}'.format(root.name, box.name, idx)

        # finish
        _ui.messageBox('Done')
        
    except:
        if _ui:
            _ui.messageBox('Failed:\n{}'.format(traceback.format_exc()))

ParametricDesignType -> create JointOrigin -> DirectDesignType (or BaseFeature) -> JointOrigin Rename

When I referred to the thing before switching the design mode after switching the design mode like, an error occurred.
I have experienced sketching in the past.

This is not mentioned in Help, but I interpret it as a specification.

Hi @kandennti In the script if we rename the JO by general names say 

for idx, jo in enumerate(jointOrigins):
            jo.name = '{}_{}_{}'.format("hello", "world", idx)

then the renaming of JO works. Probably @MichaelT_123 is seeing some other issue. 

Thanks

@sunil.v.b .

I didn't notice.
Thank you for pointing out the mistake.

[MichaelT_123]

So, what is your verdict Mr Sunil.V.B.?

• There is a problem
• Everything is OK
• Probably Michael_123 has a wrong monitor?

Have you had a chance to look at the code surrounding the error message?

Have you investigated memory dumps in CER_s?

Regards

MichaelT

1. For your information, I have spent some time (unnecessarily) assessing the validity of each answer.

[sunil.v.b]

Hi @MichaelT_123 

Surely there is a problem, its only that we are not able to reproduce it our end through UI. Looked at the CER reports as well and tried workflows around that, unfortunately not able to reproduce. We will continue with our efforts and if we find anything will let you know.

It will be super useful for us, if you can send us a sample model, sample script if this issue is specifically API related and a screen cast showing the issue. This will help us reproduce and debug the issue at our end.

Thanks

Hi, Mr Sail.V.B.

OOOhhhh good to know that I am not totally wrong (stupid 😀).
As per the sample code, in anticipation of your follow-up (thank you for it) I have prepared it already. I hope that it shows where the problem occurs in its naked form.
As per the cause of the problem consider looking on C-side (the core of F360 under python skin) how jointOrigin.name string memory is allocated in the context of whole JO structure/class.

Thank you @MichaelT_123 for sharing the sample script. In this API script New component and Joint origin is being created in Base Feature Active mode (startEdit()). However, in Base Feature Acitive mode, we cannot create a New Component and also Joint Origin; in general assemble commands are not available in Base Feature activie mode. Please see screencast video at the end showing this.

If the intent is to create the component, Joint origin in DM, then below code could be used (I just modified the script you shared). Later this design can be converted to Parametric design as well if needed to work in PM.

# modified to DirectDesignType instead of ParametricDesignType with BaseFeature
import adsk.core, adsk.fusion, traceback
def run(context):
    ui = None
    try:
        app   = adsk.core.Application.get()

        app   = adsk.core.Application.get()
        des   = adsk.fusion.Design.cast(app.activeProduct)
        ui    = app.userInterface
        root  = des.rootComponent   
        des.designType = adsk.fusion.DesignTypes.DirectDesignType

        occ_A  = root.occurrences.addNewComponent( adsk.core.Matrix3D.create() )
        comp_A = occ_A.component
        comp_A.name = 'comp_A'
        occ_A.activate()


        sketch_A = comp_A.sketches.add( comp_A.xYConstructionPlane, occ_A )   

        line_A             = sketch_A.sketchCurves.sketchLines.addByTwoPoints( sketch_A.originPoint,  adsk.core.Point3D.create(1,0,0) )
        jointOrigins       = comp_A.jointOrigins
        jointGeometry      = adsk.fusion.JointGeometry.createByCurve( line_A, adsk.fusion.JointKeyPointTypes.StartKeyPoint ) 
        jointOriginInput   = jointOrigins.createInput(jointGeometry)
        jointOrigin_A      = jointOrigins.add(jointOriginInput)    
        # Rename jointOrigin_A
        isRename           = True
        if isRename:
            jointOrigin_A.name = 'jointOrigin_A'   

        des.activateRootComponent()
