Use to make curves into reference curves.MAE 455 Computer-Aided Design and Drafting4Editing Profiles1) Double-click on sketch to activate it.2) Draw new curves and delete or trimexisting curves as required to create proper profiles.3) Constrain curves as required.4) Finish sketch.5) Re-open and adjust any dependent features that may have warnings or errors.3MAE 455 Computer-Aided Design and Drafting5Extrude Command1) Select tool ( ) 2) Select sketch, edges, 3D curves, or face to extrude.3) Extrude options:– Start/end options: Distance to start/end | Start/end at next/selected face or plane | through all– Solid Boolean options: Create/Unite/Subtract/ Intersect – Use “Create” if possible.– Direction– Taper angle– Profile offset distances– Advanced options are set using PreferencesModeling.MAE 455 Computer-Aided Design and Drafting6Revolve Command1) Select tool ( )2) Select sketch, edges, 3D curves, or face to revolve.3) Select revolve axis4) Revolve options:– Start/end options: Angle to start/end | Start/ end at trim face– Solid Boolean options: Create/Unite/Subtract/ Intersect – Use “Create” if possible.– Profile offset distances– Advanced options are set using PreferencesModeling.• Revolved profile must be on one side of revolve axis!4MAE 455 Computer-Aided Design and Drafting7Sweep Command1) Select InsertSweepSweep Along Guide2) Select cross-section profile (sketch, edges, 3D curves, or face)3) Select sweep path (sketch, edges, 3D curves, or face)4) Sweep Options:– Solid Boolean options: Create/Unite/Subtract/ Intersect – Use “Create” if possible.– Profile offset distances• Sweep profile must be at start of sweep path!!• Sweep profile must be perpendicular to sweep path!!• Swept shape must not
