Yellow Triangle Alert

Yellow Triangle Alert

Yellow Triangle Alert

(OP)
I just performed the pattern feature operation in NX 8.5, and I am getting a yellow triangle alert next to it in the part navigator. The features I "patterned" were fairly complex, at least by my standards. I included 14 different features in the pattern operation. A few of those features were Subtract Operations that involved some Swept objects.

When I hover over the name in the part navigator, it tells me that " Subtract (#s) do not support changing pattern method after creation. Choose desired method carefully". I have gotten this warning in the past when I have patterned a Subtract feature, but it never resulted in a yellow triangle in the navigator when completed. That makes me think something else wrong, but I can't find any other information on it. The pattern instance seems to be exactly what I want, but I can't get the alert to disappear.

How can I verify the cause of the alert? If it is just warning me that I cannot change the pattern method (I won't ever need to) how can I get rid of the alert in the navigator? Thanks

RE: Yellow Triangle Alert

If the feedback item is 'Yellow' it's simply a warning and NOT an error. It should still work, within the limits indicate. If it were 'Red' then there was a failure of somekind.

RE: Yellow Triangle Alert

By the way. I've always found the warning "<some feature> do not support changing pattern method after creation. Choose desired method carefully" really uneeded. During the pattern options selection it creates an impression that you're doing something wrong when actually you're not. Is it possible to disable it permanently?

RE: Yellow Triangle Alert

It's possible that you may no longer see this starting with NX 9.0 are we've made some changes to Pattern Feature to support certain cases more fully. There were a few issues depending on whether you started out creating a Pattern using the 'Simple' instead of the 'Variational' method. What was done was to support more cases where you can use 'Simple' (which is more efficient in terms of model size and speed of update) versus 'Variational'. While there are still some times where 'Variational' will still be needed, there are more cases where to can start in 'Simple' and still make it work without any warnings or having to swtich to 'Variational' due to some edit later on.

RE: Yellow Triangle Alert

Thanks, John! Good to hear. Have to admit that speed of update of the Variational method is an issue.

RE: Yellow Triangle Alert

Yes, the biggest issue with the first implementation of Pattern Feature was that if you first created the Pattern using the 'Simple' mode you could NOT later edit it to change it to 'Variational' if you discovered that it needed to have 'Variational' to start with. More recent versions of NX will now allow you edit a Pattern, changing it from 'Simple' to 'Variational' (and vice versa) as well as supporting more situations where 'Simple' will work thus assuring the best possible update performance. In fact, with the later versions of NX, I would ALWAYS use 'Simple' unless I receive an explicit warning that what I'm doing requires that I use 'Variational' instead.
