Feature tree in NX 9.0

[Karlis]

Hello, I am having some hard time understanding the feature tree.
What I have is a model part, that has two things imported in it. Facet body and IGES curves. I find it strange that I can not see these features anywhere in the feature tree, I would like to group the IGES curves for easier show/hide operation. I even performed a section analysis on the facet body, and the feature never popped up. Only the curves did. Can someone please explain this to me?
And also I have another question.
Suppose my IGES curve is a spline generated from performing a section analysis on a facet body. Now since the facet body is crippled a bit, the output curve is spiky and unpleasant. Is there a way to smoothen this spline? If there is a command, please tell me where to find it.
Thanks a lot

The imported curves and faceted body are not a feature, so that is why they do not appear.
Try either of these however:
Menu -> Format -> Group -> New Group. You can then select the curves, add them to your new group and the group will appear in the feature tree to hide/show (see image).

or

Change the part navigator to timestamp order (see image).

Faceted bodies are exactly that, faceted, so the section results will never be entirely smooth.
You can however use the Menu -> Edit -> Curve -> Smooth Spline to smooth the curves.

Thanks for thehelp PhoeNX.
The weird part is why arent facet bodies and iges splines considered features. Its really messy to find and erase teenie tiny lines in the model that have been generated from facet scrap. In solidworks, every spline showed up in the feature tree, so did the facet body (though not entirely supported). It may be just my opinion, but it was a lot easier to handle the model.
Another thing, I do not seem to have the folder "model1" in my part navigator, even though the timestamp order is active.
Is there anything else I need to set before it shows up?

That is probably a Reference Set and I'm going to assume you've not added anything to a Reference Set if it's not showing up OR the Reference Set is being filtered out.

In NX, a 'Feature', at least as far as the Part Navigator is concerned, is either a Solid or Sheet body or any NX object which has what we call an imbedded 'method', sometimes called a 'history record', which means that it can be associatively created, can be edited parametrically, participates in model updates, etc. Simple curves, either created in NX or imported, as well as things like faceted bodies, are examples of items which are NOT considered to be 'features' and thus will not show up in the 'Model History' section of the Part Navigator, when in 'Timestamp Mode'. Now when NOT in 'Timestamp Mode', some of these non-features may be be accessible from the Part Navigator main body or from a folder titled 'Unused Items'.

I say this only in case......and if you're able to remember this, in the future please do not change the Part Navigator when in Timestamp mode to show non-associative entities like curves and/or points. I'll never have any interest in seeing a clutter of non-associative geometry in my Part Navigator. If you do change ever change it, please leave an option to exclude these items.

Trust me, we're not considering that, at least I've never heard of any serious proposal to do so. Note that I just spent a couple of days reading project specs for the next full version of NX and I saw nothing remotely similar to this.
