Pattern Feature NX8.5 with Variational Method
Pattern Feature NX8.5 with Variational Method
(OP)
Hi All NX Expert,
I am just developping an interesting part showing this option and before opening a call to GTAC I would like to have your opinion about the behaviour of this function.
Edit the Pattern Linear
Add the feature substract
==> all occurrences of sketch move and the result is bad of course
(Remark: Edit Feature Playback give the same result)
I also tried to create a point before the sketch_000 with the same issue.
Thanks in advance to your feedback

RE: Pattern Feature NX8.5 with Variational Method
You have got the same bad result by moving the substract after.
Open your part,
blank all solids and datums
Then have a look at the position of sections relative to the intersections
Try also to increase the instance number

RE: Pattern Feature NX8.5 with Variational Method
The approach that you took would not work since you were making a linear Pattern which means that it's actually LINEAR (the intersection points are not taken into consideration). The approach I took requires two separate Pattern features, a 'linear' one for the Datums and Intersection curves, and the second 'general' Pattern of the Sketch referencing a 'Point Set' created from the intersection of the Datums with the profile of the variational Sweep. Granted, this then required that each subsequent Swept body be created as a separate feature. Of course, once created, they could all be Subtracted at once.
While I suspect that this is not as simple as you have liked it to be, I do think that it's actually the model that you were expecting, correct?

RE: Pattern Feature NX8.5 with Variational Method
The result topology is correct. I have already done this using instance geometry with point to point method.
But I would like to have a very simple MNT using Pattern Feature.
You say " the intersection points are not taken into consideration " but my part was saved with a correct position of the different instances, then try feature playback on my part ?
So, I will open a PR or maybe an ER
