I have a mirrored feature and then go back and edit it. In doing so it seems to very rarely fix the mirrored features which should be dependent on the others I would think. Am I doing something wrong when I mirror it?
Annoying, huh I avoid mirrors because, like you, I can't get the hang of it either. I need reliable associativity. If a rotational pattern will do the same, it is the go-to feature.
edit: old history pretty much asking the same... Mirror Feature Issue
I do not like mirror. I think it is best to just draw all of the parts. It does take longer sometimes to sketch everything, but it does save time regenerating and failing. That is my take on it. It seems pattern and mirror messEs up when regenerating.
The Mirror feature is very limited in functionality unless you mirror the whole feature tree, i.e Mirror Merge. Unfortunately not out until maybe mid 2017, but from Creo 4.0 M020 I believe it will behave as you and all of us Creo users want.
That doesn't say they fixed it, just "enhanced" it.
I've learned to read PTC hype with a very careful eye.
Like the disclaimer below that actually says "if we get it working without actually touching the core code"...
I was just trying to resolve this same issue and stumbled upon a fix that worked at the time. If you right click on the Mirrored Merge id in the model tree, click on Edit Definition, then click ok it regenerates the mirror from the updated file. There is a place to choose the file it is mirroring, it would not let me change it but by editing the definition it does seem to regenerate from the updated file.
When modifying a mirrored feature, be sure to modify the original and not the mirror. Modifying the mirror may break the mirror link. Also I have found that mirroring modifying features, such as rounds and chamfers, can cause problems.
It's funny, Creo is billed as high end, yet it can't mirror? I'm fighting this right now.
I complain about this stuff and then the Creo apologists come and attack me. "We just use some crazy workaround and are happy that way. And, besides, why would we need it when Creo can do trajpar??"
I tried editing the mirror and then using a different plane and then re-editing and using the desired plane and it DIDN'T UPDATE! You would think this would force a rebuild.
News Flash: SolidQuirks can handle mirrors anywhere from simple to complex with half it's code tied behind it's back.
Being able to leverage symmetry is a fundamental solid-modeling technique.
Just loaded version 4 and am really liking the improvements. Starting to feel a lot more like SolidQuirks, without the mirroring capabilities that is.
