    2/15

    SolidWorks Create a part document.

    Set units, precision, drafting

    standard, other. Select a Sketch Plane:

    Front, Top, Right, created, face,etc.

    SolidWorks Select a 2D Sketch tool vs. a

    3D Sketch tool.

    Create a sketch (CornerRectangle). Understand thelocation of the origin. WHY!!

    4/15

    SolidWorks The origin represents

    the intersection of the

    Front, Top and RightPlanes.

    origin

    SolidWorks Insert all needed geometric

    relations and dimensions

    relative to the origin. Use theorigin in your sketch. The sketch should be fully

    defined (displayed in black).

    WHY?

    Example 1 - Use the Origin in your

    Sketch

    Create a 2D Sketch of a circle.

    In this example, the origin isnot part of the original 2DSketch of the circle.

    Insert a vertical geometric

    relation to the origin and twodimensions relative to theorigin to fully define the sketch. The sketch should be fully

    defined (displayed in black).WHY?

    Example 2 - Use the Origin in your

    Sketch

    Create a 2D Sketch of a circle.

    In this example, the center ofthe circle is at the origin. Acoincident geometric relationsis added by SolidWorks.

    Only a single dimension isneeded to fully defined thesketch. The sketch should be fully

    defined (displayed in black).WHY?

    What Sketch Plane do you start on for

    your 2D Sketch?

    Why do youstart on acertain SketchPlane:Example

    Front

    TopRight

    *The plane or face you select for the Base sketch determinesthe orientation of the part.

    2D Sketch States

    Sketches are generally defined

    in one of the following states.Color indicates the state of

    individual sketch entities:

    Under Defined. There is inadequatedefinition of the sketch, (Blue). The

    FeatureManager displays a minus (-)

    symbol before the Sketch name.

    Note: When you create freeform shapes, generally through splines, these

    shapes can be very difficult to fully defined.

    2D Sketch States (Cont:)

    Sketches are generally

    defined in one of thefollowing states. Color

    indicates the state of

    individual sketch entities: Fully Defined. Has complete

    information, (Black). The

    FeatureManager displays no

    symbol before the Sketchname.

    Only two dimensions with geometric relations. This will effect your drawing. HOW?

    Sketches are generally

    defined in one of thefollowing states. Color

    indicates the state of

    individual sketch entities: Over Defined. Has duplicate

    dimensions, (Red/Yellow). The

    FeatureManager displays a (+)
