Am I Losing My Mind? (Silhoettes)

Am I Losing My Mind? (Silhoettes)

Am I Losing My Mind? (Silhoettes)


Notice the silhouettes of the large cylinder are in the right place. When you rote the bodies in modeling you will get silhouettes like what is showing on the holes in the block. Silhouettes dont automatically update.

But I would swear that I used to be able to just hit Update Display and it would clean them up when in modeling. Today it doesnt seem to work. Unfortunately everyone else I ask here seems to never use silhouettes to begin with, so they have no idea.

Am I losing my mind that I remember being able to just do something real simple and they would update?

RE: Am I Losing My Mind? (Silhoettes)

"Update display" should do the trick. If not, try "regenerate work".


RE: Am I Losing My Mind? (Silhoettes)

Yes cowski, that did work. Strange that Update Display is no longer working though. I wonder what changed here to cause that.

Thanks for the help

RE: Am I Losing My Mind? (Silhoettes)

Try render to dimm and then back to static

RE: Am I Losing My Mind? (Silhoettes)

I did that once before and it updated it, but now when I change the renderings it doesnt seem to make a difference. However I have the button for perspective right there and switching that back and forth once updates it.

RE: Am I Losing My Mind? (Silhoettes)

Years ago, 'Update Display' did almost the same thing as 'Regenerate Work View', but over time, as the display hardware got better, the 'Update Display' option was modified so as to be more efficient (IE faster) taking more advantage of the hardware. However, for some aspects of a model, such as when using the wireframe display, it still requires a full update such as what happen when you perform a 'Regenerate Work View'. Note that there is a display option, titled something like 'Shade Edge' display or something, that will also show a 'wireframe' display of the model without having to do any sort of display update. In fact, even as you rotate the model dynamically, the edges, including silhouettes, will update in real-time.

RE: Am I Losing My Mind? (Silhoettes)

I find Wireframe with dim edges. This allows the outer silhouettes to update on the fly but does not show the silhouettes for any holes. Which is better than nothing. Makes me wonder if they can update the silhouettes as you roll the part on outer silhouettes, I wonder why they dont just do that for a static wireframe rendering.

Either way I now have different options as "Update Display" doesnt do what I thought anymore.

Thanks everyone.

RE: Am I Losing My Mind? (Silhoettes)

I tested the static wireframe display on an open part I have and the "update display" worked to update the silhouettes. I'm currently using NX 10. I'd suggest trying it on a different part to see if you get the same results. Does the large cylinder interfere with the block? I know in drafting that interfering bodies can cause display issues, but I don't remember having that issue in modeling views...

Edit: I see your other thread today where you are creating a journal to change some display style stuff. If you were testing that journal before you got the display issues, I'd suggest restarting NX and trying again. Sometimes errors in journals can leave NX in an odd state where things don't work as they should, even after exiting the journal.

RE: Am I Losing My Mind? (Silhoettes)

Hi cowski

Currently we are running NX11

I went to two other people and had them test it and theirs did not update either. So I am fairly certain it is either NX11 or we just have something going on with our settings here.

Since we moved to NX11 from NX9, a year or two ago, I have not used it nearly as much. I help with figuring out problems when they have one and making buttons and such, but most of my work is outside of NX these days. So it very well could have changed with that change over and I never noticed until recently. Or an update changed a setting or something and I never noticed before.

Its not a big deal since most of them dont even seem to use silhouettes anyway. It was just something I noticed and I was wondering if I was remembering wrong.

RE: Am I Losing My Mind? (Silhoettes)

You could add the Regenerate View to the pop up dialog. That works - at least in NX11

"Makes me wonder if they can update the silhouettes as you roll the part on outer silhouettes, I wonder why they dont just do that for a static wireframe rendering.

The reason is that these display modes are handled by different parts of the computer.
The "static display" is processed by the CPU and all the other display modes processed by the graphics adapter.
And since the graphics adapter is factor n quicker handling the graphics than the CPU, more and more graphical "things" is handled by it and fewer by the CPU.
( when i started playing with this system , graphics adapters capable of spinning shaded data where so expensive that not all computers had one. Wireframe display only.)
But, notice that you can change the settings for the accelerated modes under Preferences - Display.
