Delete Useless Elements 3

[CAD2015]

Hi,

Catia V5 has a tool named "Delete Useless Elements".
It deletes usless elements (like curves, points, etc).
I was wondering if NX has a similar tool......
It helps a lot, especially when we update a file previously built by someone else.,,,,,,,,,,,,,,,,

Go To: File (pull-down) -> Utilities -> Part Clean-Up
expand everything, and see if what is there if what you want.

File -> Utilities -> Part Cleanup...
In the moderate delete actions section there is an option for "Delete Unused Objects".

Also, in the part navigator, switch out of timestamp mode and you will see a folder called "Unused Items". These objects can generally be deleted without affecting the model.

Thanks,
Part Cleanup doesn't do anything (I've made a simply line, for evidence and than runned Part Cleanup; it didn't delete that line).
Any other option?................

This is a good time to look at the "Unused Items" folder. In the part navigator right click in some white space to the left of the tree and make sure "Timestamp Order" is unchecked. Open the unused items folder and see if you line is listed in there.

The 'Delete Unused Objects' option under the Part Cleanup utility does NOT apply of geometric objects, but rather to internal objects created during other modeling operations which are not always purged from the part file once they are no longer needed.

The best approach is the second one suggested by cowski as that will show you all the geometeric objects whic have not yet been referenced (i.e. 'used') by some other object and therefore are, by definition, 'unused'.

Just a comment in passing; I was amused by the use of the term 'Useless Elements' by the people at Dassault Systèmes as the word 'useless' is subjective while 'unused' is purely objective. In other words, to say something is 'useless' is to make a judgment about the value of something which I don't think we are quite ready yet to turnover to a software application

This one works!
Thanks!

So why does "Timestamp order" need to be unchecked for "unused objects" to work?

 

[JohnRBaker]

In 'Timestamp Order' ALL objects (at least those which are features) are already shown under 'Model History', even those which are at the moment 'unused', however when not in the 'Timestamp Order' mode, only Solid Bodies and their parent objects are shown in the main part of the Navigator and therefore without a separate folder for any sheet bodies or nonreferanced curves and/or sketches there would be no way of knowing that they even existed in the part file, at least not when looking at the Part Navigator. Granted, I guess we could have included an 'Unused Items' folder when in 'Timestamp Order' mode as well, but it would be redundant and perhaps even a bit confusing to some people.
