Inventor 11 TUTORIAL 3
Surface Caps Learning Objectives
Aftercompletingthistutorial,youwillbeableto: Construct and use surface features in solid modeling Incorporate surface features in part design when appropriate Construct Revolved surfaces Use surfaces for Splitting solids
Required Competencies
Beforestartingthistutorial,youshouldhavebeenableto: Construct, constraint and dimension sketches Project geometry on sketch planes Extrude sketched profiles Revolve sketched profiles Loft sketched profiles Understand the concepts of work and placed features Understand how to manipulate the history tree in the browser
