Lab Exercise 2: Creating the Intake Cover

Objectives

After successfully completing this exercise, you will know how to: Create basic parametric surface features.

Scenario

You have been assigned to work on the design of a new intake cover.You create basic parametric surface features using rotational andgeneral blend tools.

Task 1. Create the INTAKE_COVER.PRT.

1. Click New from the main toolbar.

Enter INTAKE_COVER.

Click OK .

2. Click Datum Planes in the main toolbar to enable theirdisplay if necessary.

Task 2. Create a surface using Rotational Blend.

1. Click Ins ert > Blend > Surface from the main menu.

2. Click Rotational > Done from the menu manager.

3. Accept the default attributes by clicking Done .

4. Select datum plane FRONT and click OK > Default .

5. Click Close from the References dialog box.

6. Click Datum Planes in the main toolbar to disable theirdisplay.

For this rotational blend surface you do the following:Sketch the sections in separate windows.Orient the sections by specifying rotational angles about the Y-axis of sketched coordinate systems in each section.Control the radial distance of the sections by dimensioning them fromthe sketched coordinate systems.

7. Click Sketch > Data From File from the main menu.

Select Cover.sec and click Open .

Enter a Scale of 1.0 in the Scale Rotate dialog box.

Zoom in on the section. Right-click on the X shaped placementhandle, and place it on the intersection of the centerlines asshown in the following figure.

8. Select on the placement handle and move the section to snap tothe intersection of the references.

Click Accept Changes from the Scale Rotate dialog box.

Notice the Sketcher coordinate system to the left of the sketch.

9. Click Complete Sketch to proceed to the next section.

Enter a rotation angle of 60 for section 2.

10. Click Sketch > Data From File from the main menu. Select Cover.sec and click Open .

Edit the offset dimension from the coordinate system, from 15 to25 .

Edit the width dimension from 80 to 90 .

Edit the height dimension from 42 to 47 .



Type Y at the prompt and press ENTER.

The Capped Ends option is only valid when using closed sectionsTask 3. Create a surface using a General Blend.

1.

Click Ins ert > Blend > Surface from the main menu. Click General > Done from the menu manager.

Accept the default attributes by clicking Done .

Select datum plane FRONT from the model tree and click Flip >OK .

Click Top from the menu manager and select datum plane TOPfrom the model tree.

Press CTRL + D to orient to the standard orientation.

2. Click Close from the References dialog box.

For this general blend surface you do the following:Sketch the sections in separate windows.Orient the sections by specifying rotational angles about the X,Y, and Zaxes of Sketched coordinate systems in each section.Specify the translation (depth) along the Z-axis between each section.Specify tangency at one end of the blended surface to the adjacent

surfaces.

3. Click Entity From Edge from the sketcher toolbar.

Select the five edges as shown in the following figure.

Click Close from the Type dialog box.

Select the lower left vertex, right-click and select Start P oint .

Click Coordinate System from the sketcher toolbar, and

place as shown.

Enter a rotation angle of -30 for X.

Enter a rotation angle of 30 for Y.

Enter a rotation angle of 20 for Z.

5. Click Point from the sketcher toolbar, and place one in thecenter of the screen.

If no entities exist when placing a saved section, the Scale Rotatedialog box does not appear. The sketcher point was placed in order toeasily scale the section using the Scale Rotate dialog box. If desired,the sketcher point could then be deleted.


Select Cover_2.sec and click Open .

Right-click on the X shaped placement handle, and place it onthe coordinate system as shown in the following figure.
