Chapter 4 Creating Placed Features

After completing this chapter, you will be able to –Create fillets –Create chamfers –Create holes –Create internal and external threads –Shell a part –Add face draft to a part –Create work axes –Create work points –Create work planes –Pattern features Chapter 4 - Objectives

Fillets Fillets add material Rounds remove material –Fillet dialog box Constant Variable Setbacks Face Full Round –Edit fillet’s type & radius

Fillets Constant Tab –Same radius from beginning to end –Single set or multiple set Select Edge and Radius –Preview image Select Mode –Edge –Loop –Feature –All Fillets –All Rounds

Fillets Constant Tab –More options –Roll along sharp edges –Rolling ball where possible –Automatic edge chain –Preserve all features Preserve All Features

Fillets Variable Tab –Different start and end radius –Edges –Point –Radius –Position –Smooth Radius Transition

Fillets Setbacks Tab –Transition from a vertex –Three or more filleted edges meet at a vertex –Fillets can have different radius

Fillets Face Fillet –Select two or more faces –Faces do not need to be adjacent –Consume features

Fillets Full Round –Fillet tangent to selected faces –Select three faces –Faces do not need to be adjacent

Chamfers –Beveled edges –Interior & exterior edges –Single or multiple selection –Edit type or distance –Method Distance Distance and Angle Two Distances

Chamfers –Method Distance Distance and Angle Two Distances

Chamfers –Edge and Face Edge Face Flip –Distance and Angle Distance Angle –Edge Chain and Setback Edge Chain Setback Preserve All Features

Exercise 4-1 Creating Fillets and Chamfers

Holes –Drilled –Counterbore –Countersink –Hole Type Simple Hole Tapped Clearance Hole Holes dialog box Placement Hole Type Size Drill Point Termination

Holes –Placement From Sketch –Hole Center –Sketched Entities Linear –Select Face –1 st Reference Edge –2 nd Reference Edge Concentric –Select Face –Circular Face or Edge On Pont –Work Point –Positioned to an axis, edge or work plane

Holes Tapped Hole –Thread Type –Size –Designation –Class –Diameter –Full Depth –Left Hand –Right Hand

Holes Clearance Hole –Standard –Fastener Type –Size –Fit

Exercise 4-2 Creating Holes

Threads –Internal and external –Graphical representation –Thread feature –Hole tool vs. Thread tool –Thread Feature dialog –Excel spreadsheet C:\Program Files\Autodesk\Inventor 10\Design Data\Thread.xls Standards

Threads –Location Tab Face Display in Mode Thread Length –Full Length –Flip –Length –Offset –Specification Tab Thread Type Nominal Size Pitch Class Right hand or Left hand

Exercise 4-3 Creating Threads

Shelling –Thin walls (thickness) –Remove material (scooping out) –Hollow inside –Shell dialog box

Shelling –Remove Faces –Thickness –Direction Inside Outside Mid-plane –Unique Face Thickness Different thickness Specific face thickness More button Shelling

More Tab When no precise shell solution exists, allows a deviation from the specified thickness –Mean –Never too thin –Never too thick –Optimized –Specify Tolerance Shelling

Exercise 4-4 Shelling a Part

Face Draft –Feature that applies an angle –Internal or external face –Face Draft dialog box Fixed Edge Fixed Plane Pull Direction –Direction –Flip Faces –Arrow displayed & direction Draft Angle

Face Draft –Fixed Edge Pull Direction Select near edge to start draft –Fixed Plane Select planar face or work plane Flip plane if needed Select planes to apply draft

Exercise 4-5 Creating Face Drafts

Work Features –Special construction features –Help position & define new features –Parametrically attached –Types Work Planes Work Axes Work Points –Different situations

Work Features Creating a Work Axis –Acts like a construction line –Infinite in length –Axis of rotation Creating Work Points –Grounded Work Point Positioned in 3D space Not associated Remains in the specified location –3D Move/Rotate dialog box

Exercise 4-6 Creating Work Axes

Work Features Creating Work Planes –Understand when you need to create a work plane –Rectangular plane –Parametric –Larger than the part –Edited and deleted like any other feature –Methods – lots of solution Visual Syllabus

Work Features Creating Work Planes –Types of Work Planes Angled work plane Offset work plane Tangent work plane 3-point work plane 2-edge or 2-axis work plane Midway between two parallel planes –Feature Visibility Off or On

Exercise 4-7 Creating Work Planes

Patterns –Duplicate the feature multiple times –Distance or angle –Types Rectangular and circular –Suppressed –Child - parent relationship –Editing

Patterns Rectangular Patterns –Rectangular pattern dialog box Direction 1 Direction 2 –Options - More button Start Termination Orientation

Patterns Circular Patterns –Circular Pattern dialog box Placement Creation Method Positioning Method Flip Linear Pattern –Pattern Along a Path Ellipse, spline, series of curves 2D or 3D

Exercise 4-8 Creating Rectangular Patterns

Exercise 4-9 Creating Circular Patterns
