Sketching Constraints Tutorial Geometric Dimensional Constraints Sketch Constraints Activity Web Tutorial 1 2 3 4 Open a model in mm Start Modeling Start Sketcher Create the sketch shown 5 Click the Profile tool for straight lines drag for radius lines 6 Extrude your sketch As a Team 1 Use the dimension tools to create the dimensions shown 2 To modify dimension appearance from menu select Preferences Sketch 3 Add 3 circles to sketch 4 Exit Sketcher Constraint tool Note Sketch Preferences To Modify Sketch 1 Need to go back to original sketch Three ways to do this Double click Left mouse button on appropriate sketch in the Part Navigator shown in Timestamp Order Sketch Sketch 000 Position cursor over part in graphics window until outline of original sketch appears in pink double click left mouse button Go to sketcher as when beginning a new sketch but once in sketcher select the correct sketch number next to the checkered flag to edit Activity continued 1 Edit Sketch 2 Add a ground fixed constraint to the bottom line 3 Add a perpendicular constraint to the top corner 4 Read your status line how many constraints are needed to fully constrain the sketch Constraint tool Show Constraints Activity continued 1 Locate one small hole using dimensional constraints 2 Dimension Size of small hole Activity continued 1 Locate 2nd small hole using 1st hole dimensions as a reference 2 Dimension 2nd hole using geometric constraint equal radius Activity continued 1 Modify location and size of 1st hole 2 Locate 3rd hole using geometric constraint concentric 3 Size 3rd hole to be 8 mm Activity cont 1 Pick the Select Constraints tool and delete the top tangent constraint 2 Add top dimension 38 mm 3 Print your sketch showing all constraints
