NX6 - Drafting, detail view hatching is inconsistent

[Kasey7]

I am having issues with detail views taken from a section view.
Some of the detail views may be hatched, some not, and some partially hatched. The models (it occurs in more than one drawing) are quite simple, and all the detail views should be fully hatched. There appears to be no rhyme nor reason why this is happening. Changes to a model that should have no bearing on a detail view, will often cause a detail view to loose or gain its hatching after the drawing is updated.

Could you at least provide some images showing what you're experiencing?

To an Engineer, the glass is twice as big as it needs to be.

Sure.
Here ya go.

The hatching in this one was not removed (via view independant view, nor hidden). The model was edited one day and the hatching disappeared after being updated.

The issue with the first example may be a tolerance problem. I would tighten the Preferences tolerance for crosshatching before creating the original sectioned model.

Which beings me to the question, in both examples, was the Crosshatch automatically added to the original section view as part of a create section view operation?

I have seen this happen before really quite rarely and have always found some minor tinkering will cause it to correct itself.

I suspect that if you adjust your hatching adjacency tolerances and/or the general tolerances for the hatched detail views and then perhaps turn the hatching off and on again that it may decide to behave. It appears to be problematic on occasion that the original view being say half the size does create itself okay, but when you add a detail view you are taking a copy and doubling the size apparently without re-evaluating the tolerances really carefully.

It may also be something to do with trying to blow up the hatching with the other elements of the view so if all else fails tinker with the spacing in the cross-hatching style.

Yes, in both examples the crosshatch is generated automatically to the original section view.

I'll try adjusting the tolerances as has been suggested. Unfortunately, I'm not at my desk today so I'll have to get back later in the week with the results.

 

[Kasey7]

Well, I was going to write that I was stumped, but I found out what was wrong (or at least what has solved my problem).
Selecting a view, then editing the View Style allowed me to tweak the Crosshatch Adjacency Tolerance. However nothing seemed to work, even after toggling the Crosshatch checkbox.
What did work however, was turning on Hidden Line Hatching, then toggling the Crosshatch checkbox. I have never used Hidden Line Hatching, and frankly I don't know why it do anything in this case (there are no hidden lines). It did though, so I'm a happy camper now.

 

[Kasey7]

Sorry, I should have added that everything was in View Style>Section (tab).

 

[JohnRBaker]

That is odd as it really was designed to address a totally different situation, one involving the hatching on 3D Breakout sections. It would be useful if we could have a copy of the file/drawing in which this was the solution to your problem.

And by 'we', I assume he means Siemens. Send your file to GTAC, don't post proprietary files willy nilly to this forum.

 

[Kasey7]

How to I go about sending the file the GTAC? I have a webkey, but I've never used the service.
My supervisor was luke warm to the idea of uploading the model, but I've modified I sufficiently to avoid any hassles. I quickly recreated the drawing example (the one with 3 sectioned details) and the same hiccup occurs, namely the detail crosshatch does not always appear. Again, toggling the Hidden Line Hatching in the Section tab of View Style solves my problem.
I was unable to replicate the detail view that had the incomplete crosshatch (the detail view on the right side of the example I submitted to this thread). Possibly because I simplified the model?
Anyways, I'm away all next week. Provided I get some info, (perhaps a link to a FAQ) on how to submit the files to GTAC, I'll upload them the first week of August.

 

[JohnRBaker]

Just call GTAC's 800-number, they will open an IR and take you through the steps needed to upload your file(s) to a secure server.
