boundingBox,

Hi TF360,

I am receiving validation error:

'Traceback (most recent call last):\n File "C:\\Users\\MichaelT\\.vscode\\extensions\\ms-python.python-2023.20.0\\pythonFiles\\lib\\python\\debugpy\\_vendored\\pydevd\\_pydevd_bundle\\pydevd_resolver.py", line 189, in _get_py_dictionary\n attr = getattr(var, name)\n ^^^^^^^^^^^^^^^^^^\n File "C:\\Users/MichaelT/AppData/Local/Autodesk/webdeploy/production/????????????/Api/Python/packages\\adsk\\fusion.py", line 18463, in _get_boundingBox\n return _fusion.CustomGraphicsEntity__get_boundingBox(self)\n ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^\nRuntimeError: 2 : InternalValidationError : pNode\n'

The supplementary calculation of boundingBox from:

cgEnt.coordinates.coordinates

gives a proper result.

Any thoughts?

After additional investigation ... the additional info.

Code works on one data but for some reason does not on the another.

Creation of customGraphics line seems to be a problem.

coords = adsk.fusion.CustomGraphicsCoordinates.create( vecCoords )

isLineStrip = True

cgEnt = cgGroup.addLines( coords, [], isLineStrip, vecStrip ) # isLineStrip = True

The types and lengths of arrays are the same,

type(vecStrip[0]) = <class 'int'>

type(vecCoords[0]) = <class 'float'>

The only difference that I can spot is that in failed data set vecCoords array contains very small absolute numbers

5.064522930128136e-32
-9.192413888621255e-32

The rest is the same.

Regards

Michael

Hi TF360,

I squeezed/simplified the problem to three points only, invoking them via two independent paths.
They produced identical results in the log file! But one bBox always failed!

Then, I closed the F360 application, rebooted the computer, and started grilling the problem again.

Surprise, surprise .... all started working as required. I am still perplexed about the cause of the problem, but I am relieved that things went back to normal, if there is such a thing!

So Sleep Well TF360!

Regards

H TF360,

Unfortunately, the problem has returned!

It is intermittent. The failed process can be successfully executed after restarting F360.

The cause is probably embedded deep in the F360 kernel ... like a rogue variable, memory leaking, etc.

Could it be possible to look 'under magnifying glasses' on CustomGraphicsEntity__get_boundingBox(self) code?

Regards

What kind of custom graphics entities are you creating? The problem might be dependent on that.

Hi Mr Ekins,

... as stated in my first post:

coords = adsk.fusion.CustomGraphicsCoordinates.create( vecCoords )

isLineStrip = True

cgEnt = cgGroup.addLines( coords, [], isLineStrip, vecStrip ) # isLineStrip = True

Regards
