Object count in Layers

Object count in Layers

Object count in Layers

(OP)
Hi,
I am using NX2 and I found the object count in different layers are more in numbers than the actual count.

For example, in one layers there is only one solid body part and if I check count in that layer, it shows 5.I tried part clean-up, but still it shows in layer.Any suggestions to clean-up these.

Thanks

RE: Object count in Layers

If you created your solid from a sketch, there are hidden datum planes on your skecth layer.

Threads also produce additional entity counts.

...And faceted bodies if you have that option turned on. A great way to check what is what on each layer, is to use SolidNX's Layer Tool. You can get it from SolidNX.com for free.

RE: Object count in Layers

Groups also appear as layer entities and components show up as two entities (for a single body component).

Also there are non-graphical entities such as groups. The objects in the group may be on one layer but the group itself can be on another.

RE: Object count in Layers

And corrupt views will appear as counts in the layer setting. The only way I know how to find out what actually is on the layer is to use inquire from GM toolkit.

Is somebody know an other way to find out what is on the layers without using GM toolkit please chip in.

RE: Object count in Layers

Suppose it's the same for NX2 (I'm on NX1), drafting objects will also increase the count.

RE: Object count in Layers

I remember when I was running the GM toolkit, when making a view I would have to temporarily move the solids to layer 253, make the views, then move the solids back to layer 1, make sure to hit the cat and folder icons (I forget what they were for, its been a year). If I didnt move the solids to 253, id get a ton of objects (drafting) on layer 1, then the file would not check and save. I sure dont miss having to make files GM compliant.

RE: Object count in Layers

Make sure you have all objects unblanked & that some of the objects aren't view dependent in model space (only visible in specific views).  Saved coordinate systems will also count as objects as well.

RE: Object count in Layers

Did you try a Part Cleanup? (File>Utilities>Part Cleanup) Sometimes deleted features / entities are retained on layers in object count. If the other suggestions did not fix the problem, this usually will. SAVE THE PART FIRST.

RE: Object count in Layers

I believe he said he tried part cleanup in his original post.

RE: Object count in Layers

If you go to Tools... Part Navigator and uncheck Timestamp order UG will list user expressions, unused items, and reference sets (and possibly a few more things I have not run across). Set up your columns to show the layer the objects are on and you can delete unneeded objects or move them to the proper layer.

RE: Object count in Layers

Nice tip cowski.  Star for you.

Thanks cowski,
Helpful tip,another star for you.

RE: Object count in Layers

Glad you found it useful, just be careful because it will occasionally report something as unused when it actually is used. Usually when I see this it is associated with a mirror body or mirror set (a solid body that is mirrored then united will sometimes report as unused). But, it will warn you if you try to delete it and if you ignore that there is always the undo command.

RE: Object count in Layers

Another star for you cowski!  That's an example of another handy tool which isn't covered well in the documentation.  These are the kind of tips that make this a very worthwhile site.

RE: Object count in Layers

suppose you create a solid in lay-1 and unite this with another solid in lay-2, the resultant solid will be in layer-2, but Ug still shows an object count in lay-1 because the solid still resides in lay-1. If you delete the unite operation the solid goes to lay-1.

This is the reason why you are seeing an object count even though the layer has no entities.

RE: Object count in Layers

Yajnas,

That is completely inaccurate in NX2 unless you are retaining the tool body.  When you Unite without retaining bodies, the tool body goes to the layer of the target body ALWAYS.

RE: Object count in Layers

Not true, solid on layer1 and solid and solid on layer2, then unite them, you end up with 1 entity on the layer of the original solid that was selected first in the unite operation.

At least in V18 it works that way. If UGS has changed it in NX, then that would be a regression.

Now, if your solid is made from a sketch, that is another story, as the sketch entitries will remain on the original layer and the solids will be combined into a single entity.

Ben,

Which are you saying isn't true?

RE: Object count in Layers

I just verified the situation on my computer.  One block on layer 1, one block on layer 2, work layer is layer 3.  Unite with layer 1 block as target solid, layer 2 block as tool solid.  The part navigator shows two items on layer 1, one item on layer two.
  The resulting solid will always be on the layer of the target body, but the tool solids remain on their initial layers.

RE: Object count in Layers

Now look at Object Count in the layer dialog box....not the same, is it?  Part navigator shows layer of creation, not layer of existence.

Tim,

We posted at the same time. I was referring to the post by san-j.

RE: Object count in Layers

ewh,

I'm not getting the same results in the Part Navigator nor Layer Dialog box in NX2.

Created a solid block on layer 1 then a sphere on layer 2, made layer 3 the work layer & united the two bodies (block target, sphere tool).  The resulting solid resides on layer 1.

Maybe there is a modeling preference or customer default that is determining these results.

RE: Object count in Layers

Ben,

Thank you for clarifying; not that I have a problem with someone demonstrating I am wrong or anything.  If I'm wrong, I wish to find out what is right.  Passing along accurate information means alot to me.

RE: Object count in Layers

Tim,
You are right again.  I was only looking at the part navigator, not the layer dialog.

RE: Object count in Layers

ewh,

Didn't mean to come off as some sort of know it all, like I probably sounded in my previous post.  Was only concerned that I might be the one misinforming other.

I think the idea that might need to be understood is that in the Part Navigator, you will see Feature or Part related information regarding layers (where created or what layer "owns" the feature or body) versus actual entity layer information, which is relayed to the user via the Layer Dialog.

Tim,
  You don't come off sounding like a know it all.  On the contrary, you have valuable experience to share with us, and have helped me out several times.
