  1. Chapter 7Advanced Part Modeling Techniques

  2. Chapter 7 - Objectives • After completing this chapter, you will be able to perform the following: • Extrude an open profile • Create ribs, webs, and rib networks • Emboss text and profiles • Create sweep features • Create coil features • Create loft features • Split a part or split faces of a part • Bend a part

  3. Chapter 7 - Objectives • After completing this chapter, you will be able to perform the following: • Copy features within a part • Reorder part features • Mirror model features • Suppress features of a part • Create a derived part based on another part or an assembly • Shrinkwrap an assembly • Create plastic and cast features

  4. Using Open Profiles • Using Open Profiles • Sketch that does not form a closed area • Extrude tool only • Extrude bi-directionally • positive or negative direction, fill direction • Match Shape

  5. Rib and Web Features • Rib and Web Features • Used to reinforce or strengthen features • Additional support and minimal weight are required • mold and cast parts • Ribs, webs, and rib networks • Single, open, unconsumed profile • Taper

  6. Rib and Web Features • Rib and Web Features • Rib dialog box • Shape • Profile • Direction • Thickness • Edit Box • Flip Buttons • Extents • To Next • Finite • Extend Profile • Extend Profile • Taper

  7. Rib and Web Features • Creating Rib and Web • Rib Networks • Use multiple intersecting or nonintersecting sketch objects • Thickness is applied to all objects • Rib Network as a • Profile • Ribs • Webs

  8. Exercise 7-1 • Creating Ribs and Webs

  9. Emboss Text and Closed Profiles • Emboss Text / Closed profile • Embossed (raised) • Engraved (cut) • Shape or Text • Geometry Text • On a plane or a curved face • Step 1 - Creating Text • Step 2 - Emboss Text

  10. Exercise 7-2 • Creating Text and Emboss Features

  11. Sweep Features • Sweep Features • Requires two unconsumed sketches • Sweep dialog box • Profile • Path • Operation buttons • Solid / Surface • Taper • Type • Orientation

  12. Sweep Features • Profile • Path • Orientation • Path • Profile

  13. Sweep Features • Type - Path & Guide Rail • Profile Scaling • X & Y • X • None

  14. Sweep Features • Type - Path & Guide Surface • Path • Profile • Guide Surface

  15. Exercise 7-3 • Creating Sweep Features

  16. 3D Sketching • Defining a 3D path • Lip or routing • Work points • Model edges/vertices • 3D Sketch Environment • 2D & 3D curves

  17. Sweep Features • 3D Sketching • 3D Path From Existing Geometry • Define path • Use existing edges • Include Existing Geometry • Projecting part edges, vertices, and geometry

  18. 3D Sketching • 3D Sketch From Intersection Geometry • Defined by a combination • Planar or nonplanar part face • Surface face or quilt • Objects • Work plane

  19. 3D Sketching • Project to Surface • Project Along Vector • Project to Closest Point • Wrap to Surface • Break Link

  20. 3D Sketching • Constructed Paths • Connecting • Work points • 3D line • Auto-Bend • Radius

  21. Sweep Features • 3D Sketching • Work Points • Grounded Work Points • Constraints • 3D Lines and Splines • Precise Input

  22. Exercise 7-4 • 3D Sketch – Sweep Features

  23. Coil Features • Coil Features • Helical, springs or coil shapes • Coil Shape • Profile • Axis • Flip • Rotation • Operation • Coil Size • Type • Pitch • Revolution • Height • Taper

  24. Coil Features • Coil Features • Coil Ends • Start • End • Transition Angle • Flat Angle • Using base & secondary feature

  25. Loft Features • Loft Features • Blends a shape between two or more sections • Area Loft • Complex shapes • Plastic or molded parts • Sections • Rails • Center Line • Points • Curves

  26. Loft Features • Curves • Sections • Rails • Center Line • Output • Operation • Closed Loop • Merge tangent Faces • Area

  27. Loft Features • Conditions • Condition Boundaries Sketches • Free Condition • Direction Condition • Condition Boundaries Face Loop • Smooth (G2) Condition • Angle • Weight

  28. Loft Features • Loft Features • Transition • Point Set • Map Point • Position

  29. Exercise 7-5 • Creating Loft Features

  30. Multi-Body Parts • Create a solid body in a part file • Derive a solid body into a part file • Split Part into solid bodies

  31. Multi-Body Parts • Edit solid bodies • Move bodies • Combine

  32. Multi-Body Parts • Export solid body • Make Part • Make Components

  33. Split a Solid, Part or Face • Part Split and Face Split • Method • Split Face • Trim Part • Remove Material • Split Solid • Split dialog box • Split Tool • Faces • All • Select

  34. Exercise 7-6 • Splitting a Part

  35. Bend Part • Bend a part • A bend line • Radius + Angle • Radius + Arc Length • Arc Length = Angle

  36. Copying Features • Browser or Feature Priority • Dependent • Independent • Paste Features • Parameters • Pick Sketch Plane

  37. Mirroring Features • Mirroring Features • Features • Dependent on the parent feature • Mirror Plane • Creation Method • Change or update • Mirror Entire Solid

  38. Suppressing Features • Suppressing Features • Temporarily turn off display • Simplify parts • Increases system performance • Unsuppress • Parent – child relationships

  39. Conditionally Suppress Features • Feature Properties • Parameter Value – If statement

  40. Reordering Features • Reordering Features • Browser • Drag horizontal line

  41. Feature Rollback • Feature Rollback • Roll back the design to an earlier state • Then place new features • Reorder • Delete all features below EOP

  42. Derived Parts • In a Part (IPT) file • Options • Body • Work Surface • Sketches • 3D Sketches • Work geometry • Surfaces • Exported Parameters • iMates • Options • Operations • Mixed • Plus • Exclude • Scales Factor • Mirror Part

  43. Derived Assemblies • In a Part (IPT) file • Operations • Combination • Plus • Exclude • Minus • Bounding Box • Keeps seems between planar faces • Reduced Memory Mode • Update • Break Link

  44. Exercise 7-7 • Creating a Derived Part

  45. Shrinkwrap • Reduce detail • Protect intellectual property • Reduce file size • Create a substitute part for use with alternative representations • Create simplified data for complex purchased assemblies

  46. Shrinkwrap • Remove detail by setting • Visibility • By Size • Holes patching • Object type

  47. Exercise 7-8 • Shrinkwrap

  48. Plastic and Cast Features • Silhouette Curves—Parting Line • Create a curve at the outermost boundary of the selected faces • Select a direction • Then create a surface that will be used as a split tool

  49. Plastic and Cast Features • Grills • Create a grill feature from a simplified sketch • Create a sketch • Create feature - fill in information in dialog box

  50. Plastic and Cast Features • Bosses • Creates a boss feature to hold a fastener • Place sketch point(s) or work point(s) • Create feature - fill in information in dialog box
