Sweep8SheetCourse: Introduction to Engineering Graphics and Visualizationcopyright 2011, Georgia Institute of TechnologySteps to Create a Swept Feature(1) Define path (2) Locate the sweep start point and position plane(3) Draw the cross-section profile to be swept(4) Use the sweep feature command and(3) Select the profile to be swept(4) Select the path that it will take(5) Perform the sweepSweeping a closed profile along a straight/non-straight path creates a swept feature.The 4 steps required to create a swept feature are as follows:9SheetCourse: Introduction to Engineering Graphics and Visualizationcopyright 2011, Georgia Institute of TechnologyDefine a Sketch Path Start a new part.Return out of sketch 1Click on Sketch icon, click on the “XZ” reference plane and draw the open path curve.Fully constrain the sketch as shown, and click the Finish button10SheetCourse: Introduction to Engineering Graphics and Visualizationcopyright 2011, Georgia Institute of TechnologyCreate the Cross Section Profile Click on Sketch icon and select the XY plane.Create a cross-section for a sweep feature from a closed sketch centered on the end of the first sketch.Fully constrain by adding the dimension and click the Return button.11SheetCourse: Introduction to Engineering Graphics and Visualizationcopyright 2011, Georgia Institute of TechnologyCreate the Swept FeatureClick on Sweep feature icon Click on Path in the dialog box and select the path curveClick on OK in the dialog box to finish12SheetCourse: Introduction to Engineering Graphics and Visualizationcopyright 2011, Georgia Institute of TechnologyThe Completed Swept Feature13SheetCourse: Introduction to Engineering Graphics and Visualizationcopyright 2011, Georgia Institute of TechnologyA Drawing of the Swept Feature14SheetCourse: Introduction to Engineering Graphics and Visualizationcopyright 2011, Georgia Institute of TechnologySwept FeaturesSwept extrusions and cutouts are constructed by extruding one cross-section (A) along one path curve (B)Define a path or cross-section by:•Drawing a Profile•Selecting an existing Sketch•Selecting a part edgeYou can use a different method for each path or cross-section in the same swept feature.15SheetCourse: Introduction to Engineering Graphics and Visualizationcopyright 2011, Georgia Institute of TechnologyCross-section ProfilesA minimum of one Cross-section is neededCross-sections must be planar and closed16SheetCourse: Introduction to Engineering Graphics and Visualizationcopyright 2011, Georgia Institute of TechnologyLofting: Controlling TwistYou can define or map the points to create a controlled twisting of the surfaces in the feature17SheetCourse: Introduction to Engineering Graphics and Visualizationcopyright 2011, Georgia Institute of TechnologyLoft: Adding Additional Cross-sectionsEach Cross-section added is added to the section dialog boxThe Cross-section order can be specified, Cross-section 1, then 3, then 218SheetCourse: Introduction to Engineering Graphics and Visualizationcopyright 2011, Georgia Institute of TechnologyUsing Part EdgesPaths and Profiles can be the edges of:–Other Features–Construction Surfaces–Intersection curvesThe Project Geometry command can be used to include part edges into a profile or
