NX Journal Python:: Creating List of All Components Loaded Into an Assembly

Journaling / NXOpen API

Hello all,

I have a quick question. Does anyone know how to construct an array of all components loaded into an assembly in NXOpen's Python API? Everything I have tried leads to the same error:

"TypeError: 'NXOpen.Assemblies.Component' object is not iterable"

I've tried code such as:


import NXOpen
theSession = NXOpen.Session.GetSession()

for x in theSession.Parts.Work.Bodies:
if x.IsSolidBody:
theBodyTags.append(x.Tag)

but this only gives me one component tag for some reason. Any help or insight on this issue would be greatly appreciated!

Thanks so much for your help!

The code above looks for solid bodies in the current work part; the tag it returns is NOT a component tag.

The code below will write the display name of each top level component contained in the current display part.

import NXOpen
import NXOpen.UF

theSession = NXOpen.Session.GetSession()
theLw = theSession.ListingWindow
theUfSession = NXOpen.UF.UFSession.GetUFSession()

def main():

workPart = theSession.Parts.Work
displayPart = theSession.Parts.Display

markId1 = theSession.SetUndoMark(NXOpen.Session.MarkVisibility.Visible, "body feature group")
theLw.Open()

# initialize list to hold components
comps = theSession.Parts.Display.ComponentAssembly.RootComponent.GetChildren()

for x in comps:
theLw.WriteLine(x.DisplayName)

theLw.Close()

if __name__ == '__main__':
main()

If you need sub components, you will need to write a recursive function to process all the assembly levels. The code in the link below is Visual Basic, but the overall strategy also applies to Python.
