1. Getting Started with NX6  USB Drive  Always use your own personnel USB Drive, do not use the hard or network drive.  Construct separate directories for each NX homework assignment.  Gateway Application  Screen Layout  Top: Top Menu Bar  Middle Top: Status Bar  Left: Left Menu Bar  Center: Graphics Window Workflows: other applications Modeling, Design Simulation, & Manufacturing  Roles:  Go to Left Tool Bar  Select Roles  Select Essentials  OK to overwrite  Customize: Right Click in Toolbar area to add/delete toolbars  Dialog Boxes: positioned by the Dialog Rail  Command Flow within Dialog Boxes: proceed top to bottom  Red Asterisk: selection/input required  Green Asterisk: selection/inputcompleted  Orange Highlight: current active selection step  Green Highlight: next suggested selection step  OK/ Apply/ Cancel  Navigators:  Part Navigator, located on Resource Bar, pin to keep open  Part Navigator  Assembly Navigator  Operation Navigator  Parts:  Items saved as parts (.prt file)  Models  Assemblies  Drawings  Help:  F1 Key on any function in any application  AllPrograms/ UGS NX6.0/ NX6 Documentation  Set up Defaults  File  Utilities  Customer Defaults  Gateway/ General/ Part: Inches  OK

2. Creating a New 3-D Model (rectangular block with a hole):  Gateway Application (NX Start/ All Applications/ Gateway):  New  New Dialog  Model Tab: Units: Inches  Drawing Tab: Units: Inches Select  Simulation Tab: Units: Inches New  ManufacturingTab: Units: Inches Model  Select Model Tab: Template  Select Template Name: Model  Input: New File Name: “Block.prt” (use Choose New File Name Icon)  OK  OK (Note: Top Menu Bar reads, “NX6-Modeling-Block.prt(Modified). You are now in the Modeling Application.  Sketch Icon (create 2-D sketch in the XY Plane that you will extrude in the Z Plane)  Create Sketch Dialog  Select Planar Face orPlane: (left click on the XY Plane)  Select Horizontal Reference: (left click on X Axis)  OK (You are now in the Sketcher Application)  Rectangle Icon  Rectangle Dialog  Rectangle Method: Select 3-point (Note Status Bar prompting to “Select the first point of the rectangle)  Cursor Select point (0,0) for first point  Cursor Select second point  Cursor Select third point  Circle Icon  CircleDialog  Circle Method: Select Circle by Center and Diameter  Cursor Select the center of the hole  Cursor Select the radius of the hole, or input/enter the diameter.  Inferred Dimensions Icon (always dimension in the sketch … aids revisions)  Cursor Select (left click) a single line of your sketch. Move dimension to desired location and left click  Repeat for all critical line dimensions Cursor Select a single circle radius, and move dimension to desired location.  Cursor Select a single circle center, then Cursor Select a line. Move the distance dimension to desired location  Finish Sketch Icon (automatically returns you to the Modeling Application)

Create 3-D Model

Extrude Icon  Extrude Dialog  Select Curve (left click onthe sketch in the XY Plane)  Select Vector (Note the Reverse Direction Icon for direction in the Z Plane)  Input Distance (the thickness of your block in the Z Plane)  Apply/ OK  File/ Save

3. Miscellaneous Modeling Aids  Reference the Top Menu Visualization Tools:  Fit Icon  Zoom Icon  Zoom In/Out Icon  Rotate Icon  Pan Icon  View Icon (trimetric, top, left, etc)  Reference ModelEditing Functions  Right click on the model to edit the 3-D Extrusion Function. There are two options:  Select Edit Parameters (edit in current model state)  Input new Distance (thickness in the Z Plane)  OK  Select Edit with Rollback (edit in prior model state)  Input new Distance (thickness in the Z Plane)  OK  Cursor highlight and right click on original sketch in the Graphics Window...
