I have a similar need to section away 1/4 to 1/3 of a large assembly model for presentation. Basically I have an entire aircraft of thousands of parts. I just want to section out a segment of the skin and airframe leaving the furnished interior for some pretty graphics. Assembly cut chokes and locks up if it cuts an entire part away within the assembly, i.e. if a small part is completely removed as a result of the cut, NX pukes.
Box Section would be great if I could reverse it to remove what is inside the box instead of what is outside the box. I am super frustrated and starting to get pressure to get my presentation completed, but there is no way I can proceed as intended.
It is easy in other CAD systems that I have worked with. In Solid Edge you can even use a sketch to cut away a section.
Any further advice for a new NX user? My company switched from Edge to NX this year, and none of us can figure this one out.
Thanks,
Jon
