Hello again everyone,
I have one problem and one question:
self.ses = NXOpen.Session.GetSession()
and then later:
for part in self.ses.Parts:
self.parts.update(part.Tag, Part(part, self.settings, self))
Raises >>> SystemError: create iterator on bad object
so basically PartCollection is not iterable
Am I doing this wrong? And if not:
Is this solved in the latest versions of NX or should I work around it with UFSession.Part.AskNthPart() over all of the parts and then PartCollection.FindObject()
I also have a question: Can I assume, that if I select and save externally a tag of a face, for certain operation over a given solid, the tag will stay reliably the same every time I load and edit the prt file?
Try getting the PartCollection as a separate object first. This worked for me:
theSession = NXOpen.Session.GetSession()
def echo(what) :
def main() :
# workPart = theSession.Parts.Work
theParts = theSession.Parts
for thisPart in theParts:
output = "Part: " + thisPart.Leaf
if __name__ == '__main__':
[ Sorry about the lost indenting. ]
Tags are not persistent across sessions.
I am surprised to hear that did not work. What did the failure look like? What release of NX10 are you using? I tested in NX10.0.3 MP4, I think.
The simple method to find a face of interest in a later session is to give it a custom name.
The other method is to use the handle. Handles were created to allow access to entities across sessions.
To see detailed information, look in the Open C Reference Guide, in the UF chapter, and see the various UF_TAG... functions, starting with UF_TAG_ask_handle_from_tag()
I am using 10.0.1.something
I will update and see what happens - then report back. I really hope that this Python API gets fixed for NX11 It is a nightmare of bad documentation and "things" that don't work currently ...
Thank you for the information about the handles!
I forgot this little bit: The failure is absolutely the same as the one in the first post, just this time it is about "parts" insterad of self.ses.Parts - it is attached as a picture.
what type of information are you trying to obtain? below is a variation of Steve's code. I have a lot of python documentation for NX10. I just need to find the time to organize and post it somewhere
