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!!

SolidWorks The origin represents

the intersection of the

Front, Top and RightPlanes.

origin

5/15

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?

displayed.
