1,Open All Components on Plane
Opens or makes visible all components on the current dynamic section plane. Available only if you have the Unigraphics NX Advanced Assemblies license.
2,Open Nearby Components on Plane
Opens all components nearby the set of already visible components that are on the dynamic section plane. In most cases selecting this button several times causes the open process to step out across the section plane until all components have been opened. This is particularly useful if you want to analyze a particular component, but only want to open the minimum number of components in the assembly. Available only if you have the Unigraphics NX Advanced Assemblies license.
