Introduction to Sketching

Task 1. Sketch entities to develop the shape of the lobe

1. Start Pro/ENGINEER Wildfire 4.0 Schools Edition if necessary.

2. If Pro/ENGINEER is already running, close all windows and remove all objects from session using File > Erase > Not Displayed...  

3. File > Set Working Directory... , and browse to HANDS-ON_WF4\03-SKETCHER

4. Click the Create New Object  icon on the main toolbar at the top left of the screen.  The New object dialog opens.

5. Accept the default settings in this dialog and click OK.

   Default templates are used when a new part or assembly is created.  The default templates are an initial design model that contains default features, layers, views, parameters and units.

6. Click the Sketch Tool  icon on the right toolbar to create a sketch.

7. Click the datum plane named FRONT as the sketch plane, then click Sketch from the Sketch dialog in the upper right corner of the screen. This brings you into the sketching environment.

8. Click the Datum Planes , Datum Axes , Datum Points , and Coordinate Systems  icons on the main toolbar.
   
   

   These buttons toggle datum planes, axes, points and coordinate systems on and off so that your graphics window doesn't become too cluttered.

9. Click on the Circle  tool.  Click where the vertical and horizontal dashed lines meet to place the center of the circle, then move the mouse away from the center point and left-click to finish creating the circle.

    Select Line, and click location 1 as shown in the figure below to start the line.  Note a rubber band line appears attached to the cursor.
    Click location 2 in the figure to end the line.  Pro/ENGINEER creates a line between the two points and starts another rubber band line.
    Click location 3 in the figure to create the second line. The two lines are shown in the figure below.
    
    

11. Middle-click to end the line creation.
