You can create, edit, copy, and paste sections in NX. The section is a very useful function in the cad modeling that used for looking at details and finding mistakes in the assemblies or complex parts. The created sections are listed in the assembly or part navigator on the left in NX
New Section

To create a new section
- Right-click on the “Section” tab in the part navigator then select “New Section.

If you want to change section direction, double click on the manipulator arrow in the graphics window. (Also, you can click the “Reverse Direction” box in the dialog box) - If you want to see the interferences in the section, click the checkbox near the “Show interference” in the command dialog box.

Tip 3: You can see the 2d view of the section by activating “Show 2D Viewer” in the “2D Viewer Settings”.
Tip 4: You can copy and paste sections.
Tip 5: You can create working areas in the big assemblies by using “Section”. Create a “Box” section around the sub-assembly or part. This creates a clear working area. Also, this might increase the performance of the graphics card.
Tip 6: You can rename sections by using different methods
- Type name in the “Section Name” bar in the “View Section” dialog
- Right-click on the section in the assembly navigator the click on “Rename” from the opening list.
