NX8 Can't Mirror a Patterned Feature

[slayer001]

Hi!


I'm using NX8 and I noticed that 'Instance Feature' was replaced by 'Pattern Feature' what I think is pretty cool.

Today I was working in a model where I did a 'Lineal Pattern' of some features and then I tried to mirror it using Mirror Feature, but I coldn't do this. Then I tried doing a mirror to the main features first, but I couldn't do the Pattern Feature of the previous mirror feature.

I want these patterned features to be associative that's why I don't want to mirror with a 'transform'

So, is there a way to mirror patterned features?

Thanks in advance

How was this problem manifested? Did you get an error or were you now allowed to select the Patterned Features or did it just execute but the results were not correct? Were these free-standing features (solid bodies) or features, such as pockets or pads attached to a larger body?

Note that I just tested this using NX 8.0.1.5 (an early development copy of the first NX 8.0 MR which be ready for release sometime after the New Year) and was able to use 'Mirror Feature' to mirror both the original feature and it's patterned copies with no problems whatsoever. Note that I tested this with stand-alone features (solid bodies) as well as arbitrary pocket which had been added to a larger body and then patterned (see image below).

The problem manifested in this way, I tried to do a Mirror Feature of a Patterned feature but I couldn't select it, this happen in the past with Instance feature and Swept operations and I found out that Instance Feature can not select a Swept but it can select a Feature group containing the swept. So, I tried to use the same 'trick' Grouping the Patterned Feature and then trying to mirror it but didn't work.

My second option was to do a mirror feature and then try to Pattern it, but an error message appeared "The supplied input represents an unsupported situation. Check the input selections.". I attached an image of this.

Exactly what is it (the feature) that you're attempting to Pattern/Mirror? Your picture doesn't really make it all that clear.

Could you provide the part file for us to test?

Well John, the feature I want to pattern and then mirror is Extrude(8).

I'm using NX8.0.0.25

I had no problem performing the Mirror Feature operation on the original Pattern Feature (I removed it from the group before performing the operation). Attached is the completed model. Note that it was saved in NX 8.0.1.5 and while it technically should be safe to open in your version of NX 8.0 I would set it aside for now since until the MR release is completed (there's at least one more phase before we certify it for customer use) and you've downloaded it.

BTW, exactly what is it that you're attempting to represent with these very shallow 'grooves' on what looks like a sectioned model?

These grooves are part of my model. I think I will wait for the update release, I hope this will fix this issue.

For now I'll use an iron crosshatch at 90° and a note for the drawing.

Thank you

I just noticed that I forgot to attach the part file so here it is...

Thank you John, you've been of a great help.

Now I'm just waiting for the update release
