CREATE A REVOLVED PROTRUSION

Create the base feature – Pick the Revolve Tool icon

In the dashboard, click

Click the Close button in the

References dialog box

Click the small forward > icon to expand,

and pick Draw a horizontal centerline through coordinate system This centerline serves

as axis of revolution

Draw another vertical centerline for symmetry

Pick to draw a section as shown below

Click to constraint sketcher geometry

Click to re-dimension as shown below

Click to modify the dimensions so that the final dimensions is shown in the figure below

Note that diametrical dimensions in four places To get diametrical dimension do the following:

• Left-click the line, left-click the centerline, and again left-click the line

• Bring the cursor where you want to locate the dimension, then middle-click that position

Constraint:

Symmetry with respect to vertical centerline - Constraint: Line

Diametral dimension

Select standard.sym Click Open

Select Entity

When prompted with Select a datum plane or symbol

to which the new symbol will be parallel Pick FRONT datum plane

Click Okay for the DIRECTION to specify the direction of the front of the plane,

according to the arrow The symbol will face in this direction

Click , and select FRONT to orient the model as front view

Pick the bearing surface (0.7874 in diameter) as shown, and enter a value
