Chapter 3 - Objectives • After completing this chapter, you will be able to • Understand what a feature is • Use the Autodesk Inventor Browser to edit parts • Extrude a sketch into a part • Revolve a sketch into a part • Edit features of a part • Edit the sketch of a feature • Make an active sketch on a plane • Create sketched features using one of three operations: cut, join, or intersect
Understanding Features • Describing Features • Sketch into a 3D feature • Base feature • Placed features • Edited, deleted, or reordered • Consumed and Unconsumed Sketches • Unconsumed sketch • not yet been used in a feature • Profiles • Feature consumes the profile • Consumed sketch
Using the Browser for creating and editing • Autodesk Inventor Browser • Displays the history of the file • Create, edit, rename, copy, delete, and reorder features or parts • Expanded or Collapsed
Using the Browser for creating and editing • Autodesk Inventor Browser • Dependent features • Parent-child relationship • Filter out some object types • Funnel icon
Using the Browser for creating and editing • Autodesk Inventor Browser • Default names • Extrusion1 • Locate parts and features • Resized while docked • Close Browser • Right-click • Double-click
Switching Environments • Switching Environments • Sketch & Part environment • Automatically • Tools available to current situation
Part Features • Feature Tools • Part environment • Panel Bar icons
Extruding a Sketch • Extruding a Sketch • Depth along Z-axis • Preview • Extrude dialog box • Shape & More tabs • Values & options • Shape • Profile • Multiple closed profiles
Extruding a Sketch • Extruding a Sketch • Operation • Join = adds • Cut = removes • Intersect = common • Extents • Type & Distance • Termination • How sketch will extrude • Distance • To Next • From To • To • All
Extruding a Sketch • Extruding a Sketch • Extents • Distance • measure two points • most recent values • drag it • units appear red • preview • Direction • 3 buttons • flip the extrusion direction • equal distances, mid-plane
Extruding a Sketch • Extruding a Sketch • Output • Solid • Surface • More • Taper • Alternate solution • Minimum solution
Exercise 3-1 • Extruding a Sketch
Revolving a Sketch • Revolving a Sketch • Create cylindrical parts • Revolve sketch around a straight edge or axis • Shape • Profile • Axis • Operation • Join • Cut • Intersect • Extents • Full • Angle • Output • Solid • Surface
Revolving a Sketch • Centerlines & Diametric Dimensions • Specify linear diameter dimensions • Quarter section • Place diameter dimensions • Changed to normal line to centerline
Exercise 3-2 • Revolving a Sketch
Editing a Feature • Editing a Feature • Feature consumes all the dimensions • To edit sketch or feature • Dimensions values • Taper • Operation • Termination • Output type • For base features, everything can be changed except join operation
Editing a Feature • Editing a Feature • Editing a Feature size • Change the dimensional values multiple methods • In Browsers double-click • right-click • expand the children, right-click • Command bar • Feature priority • Update button
Editing a Feature • 3D Grips • Used to push or pull the faces • Extruded feature • Revolved feature • Sweep feature
Editing a Feature • Move Feature • Move a face of a part • 3D Grips • Triad move
Editing a Feature • Editing a Feature • Renaming Features and Sketches • Default name • Locate • Descriptive to your design intent • Rename, slowly double-click • Feature Color • Parts become complex • Feature Properties dialog box
Editing a Feature • Editing a Feature • Deleting a Feature • Failed Features • Browser turns Red, an alert • Not successfully regenerated • Undo • Sketch Doctor • Editing a Feature’s Sketch • Add & remove objects • Adding geometry, lines, arcs, circles and splines • Deleting geometry
Exercise 3-3 • Editing Features and Sketches
Sketched Features • Sketched Features • You draw on a plane • Add or remove material from the part • Unlimited • Needs it’s own plane
Defining the Active Sketch Plane • Defining the Active Sketch Plane • Each sketch must exist on its own plane • Requirements to assign a plane • Inventor Part • Part active • Planar face or Work plane • Make a sketch active • Face Cycling • Dynamic face highlighting • Help select the correct face • Select Other tool • Time delay
Exercise 3-4 • Sketch Planes
Projecting Part Edges • Projecting Part Edges • Building parts partially based on existing geometry • Reference faces, edges, or loops • Associative link • Direct Model Edge Referencing • Automatically project edges • Create dimensions and constraints • Control the automatic projection
Projecting Part Edges • Projecting Part Edges • Creating Reference Geometry • Move the cursor over an edge • Click an edge • Reference edges • Project Loop and Chain Option • Project Geometry tool • Edges • Loops • Faces
