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
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
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
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
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
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
Exercise 7-1 • Creating Ribs and Webs
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
Exercise 7-2 • Creating Text and Emboss Features
Sweep Features • Sweep Features • Requires two unconsumed sketches • Sweep dialog box • Profile • Path • Operation buttons • Solid / Surface • Taper • Type • Orientation
Sweep Features • Profile • Path • Orientation • Path • Profile
Sweep Features • Type - Path & Guide Rail • Profile Scaling • X & Y • X • None
