• 1. NX7.5 : Basic Training Course

2. GETTING STARTED Start Programs UGS NX 7.5 NX 7.5 It may take a minute or so for NX to start the first time. 3. Once opened, you will be presented with the window Open a New File To create a new file there are two options. You can click on the New tab on top of the screen or go through the File drop-down menu. To start modeling, you must first create a part file. NX part files use the extension .prt for both components and assemblies of components. 4. This will open a new session, asking for the name and location of the new file to be created. You need to select the units (inches or millimeters). Open a New File 5. NX7.5 Modeling Interface Once the new file has been created, the NX modeling interface will open, the interface for NX contains numerous icons, lists, text prompts and other features. 6. The NX 7.5 window 7. Save Part Files SAVE: This option will save the part on screen with the same name as given before while creating the part file. SAVE WORK PART ONLY: option will only save the active part on the screen. SAVE AS: option allows you to save the part on screen using a different name. SAVE ALL: This option will save all the opened part files with their existing names. SAVE BOOKMARK: This option will save a screenshot of the current model on the screen as a .JPEG file and bookmarks. 8. Close Part Files To close a part files Click FILE CLOSE. If you close a file, the file will be cleared from the working memory and any changes that are not saved will be lost. Therefore, remember to select SAVE AND CLOSE or SAVE ALL AND CLOSE or SAVE ALL AND EXIT. Exit an NX7.5 Session To Exit an NX 7.5 Click FILE EXIT 9. Open a Part File To create a Part file there are two options. Click FILE OPEN or click the Open icon from the Standard toolbar at the top of the screen. The Open Part File dialog will appear. You can see the preview of the files on the right side of the window. You can disable the Preview by un-clicking the box in front of the Preview button. 10. TOOL BARS Add or remove toolbar buttons Customize and display toolbars Roles 11. Using the mouse 12. Using the mouse 13. Shortcut menu Radial toolbars 14. Orient View Home key: Orients the current view to Trimetric. End key: Orients the current view to Isometric. F8 key: Orients the current view to a selected planar face or datum plane or the planar view (top, front, right, back, bottom, left) that is closest to the current view orientation. View triad 15. Selecting objects Deselecting objects You can deselect and object by holding the Shift key as you click it. To deselect all objects in the graphics window, press the Esc (Escape) key. Quick Pick 16. The User Interface option PREFERENCES BACKGROUND The background color refers to the color of the background of the graphics window. NX supports graduated backgrounds for all display modes. You can select background colors for Shaded or Wireframe displays. The background can be Plain or Graduated. Valid options for all background colors are 0 to 255. PREFERENCES Objects The Object will be set here work layer (assign the object to work layer), color of the object and translucency of the object. 17. USING LAYERS Status : Work Selectable Visible Only Invisible Choose Format Layer Settings to access the Layer Settings dialog box. Name This column shows the active Work layer (a layer is visible and selectable if its check box is checked). Visible Only If a check box in this column is selected, the objects on that layer can be seen but not selected. 18. Coordinate systems Absolute Coordinate System The Absolute Coordinate System is the coordinate system from which all objects are referenced. Work Coordinate System The Work Coordinate System (WCS) is what you will use for construction when you want to determine orientations and angles of features. The axes of the WCS are denoted XC, YC, and ZC. (The C stands for current). 19. Sketching A Sketch is a named set of 2D curves and points located on a specified plane or path. You can apply rules, in the form of geometric and dimensional constraints, to establish the criteria your design needs. Ways to use sketches 20. Choose INSERT SKETCH in TASK ENVIRONMENT We will use second method of creating sketch. The screen will display the Sketch options. You can choose the sketch plane, direction of sketching and type of plane for sketching. 21. Sketch curves 22. Name sketches in the Modeling application To name a sketch in the Modeling application use the Sketch Properties dialog box. In the Part Navigator or in the graphics window, right click the sketch and choose Properties. Click the General tab. In the Name box, type the new sketch name. Click OK. 23. Finish Sketch Use the Finish Sketch command to exit a sketch and return to the application or command you started sketching from. Snap Point options 24. Types of constraints Geometric Constraints Tangent Vertical Horizontal Offset Perpendicular Coincident 25. Dimensional Constraints 26. Convert To/From Reference overview Use the Convert To/From Reference command to convert sketch curves from active to reference, or dimensions from driving to reference. Active curves Reference curve Reference dimension Driving dimensions 27. Sketch curve functions 28. Quick Trim overview 29. Quick Extend overview 30. Make Corner overview 31. Fillet overview 32. Chamfer 33. Types of swept features Extrude Sweep a section string (1) in a linear direction for a specified distance. Revolve Rotate a section string (1) around a specified axis (2). 34. Sweep Along Guide Sweep a section string (1) along a guide string (2). 35. Boolean Operations: Unite: The unite command adds the Tool body with the Target body. For the above example, the output will be as follows if Unite option is used. 36. Subtract: When using the subtract option, the Tool body is subtracted from the Target body. The following would be the output if the rectangle is used as the Target and the cylinder as the Tool Intersect: This command leaves the volume that is common to both the Target body and the Tool body. The output is shown below.
