The Revolve feature is one that converts 2D drawings into round shapes. You can use the Revolve feature to make a wide variety of shapes.
For example, the 2D shapes on the left above, when revolved, results in the 3D shape on the right.
To create a Revolve shape:
- Choose File | New.
- Choose View | Top.
- Draw a circle and set the diameter to the outer diameter of the
shape.
- On the numeric bar set Z to the overall length of the shape.
- Choose View | Front.
- In
the right side of the dotted axis line draw a 2D closed shape that
touches 3 sides of the rectangle (see above). Keep the shape away from
the center axis if you want a center hole. There must be no overlapping
lines or open lines.
- On the numeric bar set Z to Revolve.
- Choose View | 3D.
To add tapping or threading with the Revolve feature use Comments To Machinist.
You can add additional features to Revolved
shapes. For example you might want to add flats, side holes
or any other non-revolved shape.
To add additional features to a Revolved shape:
- Select the appropriate view from the View menu, other than the view containing the Revolve line.
- Draw the desired additional feature.
- Set the Z value to a negative value for a recess, a positive value for a protrusion, Air Inside for a hole or cutout, or Air Outside to remove all material outside the associated line.
- Choose View | 3D to check the result.
Examples of the above method of adding a feature to a Revolved shape:
- For a chess pawn down sliced down it's center: Draw the side profile in the Front view and set Z to Revolve. Then, in the Top view draw a D shape and set Z to Air Outside.
- For a wrench flat: Draw a rectangle in a side view and set Z to a negative value.
