Fillet problems in NX
Fillet problems in NX
(OP)
I'm having trouble with a design when I try to make a fillet, part of it disappears. I used a sheet to do the split of the solid and when I added the fillet the middle part disappears. I've attached a power-point giving step by step on what I'm doing. Somebody let me know what I'm doing wrong if you know as this is not the first time I've run into this problem.





RE: Fillet problems in NX
Go to Edit - Object Display, and select your object. Make sure the translucency is set to 0. Expand the settings portion of the dialog box and check "Apply to all faces of selected body". Click ok or apply and see if that works.
If that is what fixes the problem I'd be interested in hearing from anyone else on why this occurs sometimes. I've had this issue in the past and been able to fix it with the above method, but just wondering why it happens in the first place or if there is a setting that needs to be changed?

Also, after applying the blend, run the examine geometry command. This will help determine if it is a geometry or display only issue.
To run the examine geometry command:
Analysis -> Examine geometry
Turn on all the body and face checks, window select around your entire model (to be sure you select all faces and edges as well as the body object itself) and press examine geometry. If one or more of the tests doesn't report as "passed", there is a geometry problem. If all the tests pass, it is probably a display driver problem.

Do you do that too ?
Usually an NX reboot will fix the issue.

Maybe it has something to do with using a sheet to cut the main body. I should approach this another way.
RE: Fillet problems in NX
This is a valid modeling technique and shouldn't cause this type of problem.
Is it possible to post your NX file (or a similar example file that shows the same issue)?

First movie just shows, that the model actually is a solid body. And it also show the information, where I can see, that there is a problem with geoemtry.
The second movie shows, how I have searched for the problem area.
The third movie shows, how I have fixed this problem. The problem can also bi fixed with some extrude on this area. Subtract or Unite. It was enough just to perform a change on this problematic area.
I hope, that the movies will help you in finding the problem and solving it.

Are you using a certified computer?
Do you have a certified graphics card?
I have seen this with a gaming graphics card in the past.

SvenBom: I did not have any luck playing any of those AVI files. I wonder what the problem is there? Don't all computers play AVI files?
looslib: I'm new at the design game so I have a question to each of your questions. I won't be discouraged if you don't have time to deal with the elementary questions. But I am trying to learn.
1. How do I find the hardware spec?
2. How do I know if I'm using a certified computer?
3. How do I find out what kind of graphics card I am using?

Thanks. I was able to install the codec and watch the videos. Even though I have changed my approach to the model, I am sure I can use the analysis tools and those Syncronizing Tools is a whole new venture for me as well.

Before the blend is applied, the model does not pass body consistency or face self-intersection tests. I suspect the same for the OP's model...

I have attached the image, that shows the problem. In the zip file, there is also a part in NX7.5, that is fixed.
An there was no need for some strange edit with sync tech like in my movies.
RE: Fillet problems in NX
Later today I would like to work on the model a bit
RE: Fillet problems in NX
RE: Fillet problems in NX
It is in NX7.5
RE: Fillet problems in NX
Another good practice is to enable self-intersecting alerts in feature creation. This is on by default but I've gotten native NX files where it was all turned off allowing the modeler to create bad geometry.
