In revolving a solid you will:

• create two new sketches

• toggle a line to fixed

• create a valid profile

• revolve the profile about the axis

Revolving

To create a revolved profile:

• decide upon the orientation of the profile

  • in this example we will revolve a goblet which stands vertically so I will use the vertical plane

• on the selected workplane create a new sketch and name it AXIS

• on the same workplane create another sketch and name it PROFILE

• select the sketch called AXIS

• draw a line to become the axis of rotation (vertical in this case)

• while the line is selected

  • from the Constraints menu select toggle fixed (stops axis moving)

• select the PROFILE sketch

• commencing on the axis draw the profile to be revolved - be sure to create a valid profile

• from the Features menu select revolve profile OR select the revolve tool from the features toolbar

• ensure that the box has the PROFILE sketch selected

• ensure that the box has the AXIS profile selected

• enter the angle of revolution (360 in this case)

• at this point you should see the revolution in preview

• click OK to complete the operation

Revolution with hole

• decide upon the orientation of the profile

  • in this example we will revolve a wheel which lies horizontally so I will use the horizontal plane

• on the selected workplane create a new sketch and name it AXIS

• on the same workplane create another sketch and name it PROFILE

• select the sketch called AXIS

• view onto the workplane (SHIFT key + w)

• draw a line to become the axis of rotation (vertical in this case)

• while the line is selected

  • from the Constraints menu select toggle fixed (stops axis moving)

• select the PROFILE sketch

• draw the profile to be revolved - leaving a space between the profile and the axis

• from the Features menu select revolve profile OR select the revolve tool from the features toolbar

• ensure that the box has the PROFILE sketch selected

• ensure that the box has the AXIS profile selected

• enter the angle of revolution (360 in this case)

• at this point you should see the revolution in preview

• click OK to complete the operation

NOTE

The size of the hole in the centre of the model depends upon the distance between the axis and the profile

Revolve a profile to remove material

• decide upon the orientation of the profile

  • in this example I will use the vertical plane

• create the design which is to be cut (a cylinder in this case)

  • draw a circle on the initial sketch and extrude to produce the cylinder

• on the vertical workplane create a new sketch and name it AXIS

• on the vertical workplane create another sketch and name it PROFILE

• select the sketch called AXIS

• view onto the workplane (SHIFT key + w)

• draw a line to become the axis of rotation (vertical in this case)

• while the line is selected

  • from the Constraints menu select toggle fixed (stops axis moving)

• select the PROFILE sketch

• draw the profile to be revolved - the profile will act as a cutter to remove material

• from the Features menu select revolve profile or select the revolve tool from the features toolbar

• ensure that the box has the PROFILE sketch selected

• ensure that the box has the AXIS profile selected

• enter the angle of revolution (360 in this case)

• select Subtract material

• at this point you should see the revolution in preview

• click OK to complete the operation
