Siemens NX


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

Creates a new section in the model. You can create more than one section. All sections are listed on the Assembly/part navigator.

To create a new section 

  • Right-click on the “Section” tab in the part navigator then select “New Section. 
  • If you want to change the name of the section type new name in the “Section name” bar.
  • You can change the type of the section from the first tab on the top of the dialog.
    The types of sections:
    • One Plane

    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. (Interference regions will be colored as red.)
