                                    7.2. - The  second  feature  is  the  keyway.  Select  the  "Front  Plane" from  the


                                     FeatureManager and click in the "Sketch" icon from the pop-up tool bar. We'll make


                                    a  cut  using  the  "Mid  Plane"  end  condition  for the  keyway.  Making  the  top  line



                                    beyond the top of the part allows us to "cut air" beyond the end of the part; this way


                                    we are sure we will cut the part. This is a common practice and is OK as long as


                                    we make the sketch big enough to accommodate possible future changes. Adding


                                    a dimension to  ensure the sketch extends past the part is a good  idea too.  The



                                    problem that may occur depending on the geometry and the feature being made if


                                    we  don't  extend  the  sketch  upward  is  that the  top  line  could  generate  a  "zero


                                    thickness" face error and would not let us continue.







                                                      Remember that we can use Mouse Gestures (right mouse click-and-drag)


                                               "  for the most commonly used commands or configure it for the tools we use


                                                      most to help us speed up the design process.






                                                      A  useful option when drawing lines is to transition from drawing a line to a



                                    tangent arc. To do this we can use the default shortcut key "A" or move the mouse


                                    back  to  the  last endpoint.  After  moving  the  mouse  back,  a  tangent  arc will  be


                                    started.  Depending  on  the  direction  that  we  move  out,  that's  the  direction  the


                                    tangent arc will  be  created.  Select the "Line"  tool  and  draw a  line,  click  in  one



                                    location to start, click in the second point to complete the first line, and instead of


                                    clicking a third time to add a second line,  move back to the second endpoint and


                                    move out to add a tangent arc. Press the "A" key to toggle between arc and line.
