Try changing the boolean option to "none" then try to subtract in a separate step at the end. This might give you a more verbose error message if/when something goes wrong with the subtract.
Perhaps you have inadvertently chosen "intersection" instead of "subtract"?
If not, try giving the cutting extrusion some length in the -Y direction so that it does not start on the same plane as the tube.
If it still does not work, try examine geometry to look for issues.
In the "settings" section of the dialog, change the "body type" option to "solid". If possible, a solid body will be created. I think the section curves need to be planar, closed loops for it to work, IIRC.
When working with the free-form surfacing commands, it is common to create sheet bodies...
I'm using NX2206 and the default location is Home tab -> Base -> More (in the "copy" section).
The command finder should show you where to find the command if you currently have access to it. Below is an unedited screenshot from my machine; note how NX expanded the dropdown and highlighted the...
Use the "command finder". It is shown in the top right corner of your screenshot (where it says "type here to search"). What happens next will depend on the version of NX you are using. Older versions will show a list of potential matches in a dropdown as you type and hovering over one will show...
If it won't allow you to attach a .prt file, try zipping the file first. That usually works.
However, with Siemens putting out a new major release every 6 months, it is becoming less and less likely that we can share files as everyone seems to be on a different release...
Try this: show/Hide -> show... -> select all solid bodies.
It is possible to hide the solid body of a component, independent of the component. When this happens, using show/hide on the component itself will have no effect.
Creating an arbitrary number of equidistant points on a spherical surface is a problem with no solution. There are some good approximations, but no closed form solution.
If your case is similar to the one shown in the other thread, you can use the linear edges instead of the faces. Or create geometry in the file just for the constraint. All the suggestions in that thread are valid and useful.
I've not yet experimented with feature templates, but one of the selling points is the ability to package everything up into a single feature. If this isn't what you are looking for, perhaps something like a reusable object would better meet your needs?
One of the required updates hosed the code formatting plug-in that was used. One of the (best) options is changing platforms, which would likely force everyone to re-register, so I'm hesitant to allow new users right now. The forum there was almost an afterthought for the site and never really...

TL-DR - 3 Siemens people said "works on my machine" then OP showed a video, turning on the "create...
