Extrude Operation in NX8.5

[spadazenon]

Dear All,

When I try to change the end limit of the extrude (double click the feature) from 10mm (Picture Scale1) to 15mm I get the result shown in Picture Scale2.

Does it happen only to me?

Thanx.

If you change extrude 3's curve selection rule to "infer" or "feature curves" it seems to work fine.

This (see attached) is what I get when I do this using NX 8.5.2.3. Kind of what I would expect and certainly not what it appears that you're getting.

Dear cowski,

It works with the way you mention only if I deselect and re-select the sketch.

Dear John, I cannot open your video file, if you could please attach it again.

Thank you both for your replies.

I right click extrude 3, choose edit parameters and change the end distance to 15 and change the curve rule. It updates properly for me, with no need to deselect/reselect the sketch (NX 8.5.0.23). If I change the distance to 15 without also changing the curve rule, I get the same result you show.

Dear John,

I can see that you have toggled the "Edit with Rollback" option instead of the "Edit Parameters" option. I use the "Edit Parameters" option cause is faster to load the feature.

When I change to that option I have the desired result but not if I have "Edit Parameters" option on (attached video).

Dear cowski,

I did it again, but it doesn't work for me. NX8.5.2.3 (attached video)

Is this happening to me only?

Thank you again.

OK, I see what you're seeing but have no explanation. It appears to be a bug. I'm going to open a PR and see what I can learn,

Please keep us posted. Thanx

Oops, I misspoke.
I did change the curve rule and distance value separately. My method did require a deselect/reselect. When I perform the edit exactly as you describe, I get the same result.
My apologies.

I went back and created a similar part in NX 7.5 and it worked fine, irrespective as to how I edited the model, therefore this is a regression. And if I open that NX 7.5 part file in NX 8.5 I now see the inconsistent behavior, which I did NOT see in NX 7.5. I will keep you posted of what I learn.
