Boss or Cutout Revolve

A sketched closed line chain or cross-section may be revolved. Revolve can be used to add or cut out material.

New revolve feature

  1. Create a New Plane Sketch.
  2. Sketch the shape to be revolved.
    • The revolve will be available when the lines on the sketch form a closed line chain.
    • You can sketch a rotation axis to the sketch or select it afterwards from it.
    • If you sketch the rotation axis, select Rot.Axis as its line type.
  3. Select OK.
  4. Select either Boss or Cutout according to whether you want add or remove material.
  5. Select Revolve.
  6. Enter the revolve properties and select OK.
  7. If you did not draw the rotation axis to the sketch, add it by selecting a line or two points.
    • You can select an edge or coordinate axis from the sketch as the rotation axis, for example.
Note:
  • You can use a cutout feature to divide a part by selecting Make New Part.
  • Draw the rotation axis to the sketch as a two-point line, and select rotation axis as the line type.
  • Edit the data of a feature by first selecting the face formed by the feature, then selecting the context-sensitive function Edit Operation.
  • You can also edit the feature sketch by selecting the sketch in the feature tree, then selecting the context-sensitive function Edit Sketch.
Note:
  • You can dimension the diameter of a part which is rotationally symmetric.
  • The dimension will change between distance and diameter when you move the cursor over the rotation axis before positioning the dimension.
  • The type of one of the lines must be Rot.Axis.
  • This works for both the Distance and the Dimension constraints.
  • After positioning the dimension you can drag the it elsewhere and it will remain a diameter dimension.

Revolving a Cross Section

You can also create a revolve based on a cross section.

  1. Select the face of the cross section.
  2. Select one of the following:
    • Revolve> Boss.
    • Revolve> Cutout.
  3. Define the revolve feature properties in the dialog box.
  4. Select OK.

Cross Section

Example: "Lathe" a spin shape into a rectangle

  • The vertical plane in the middle of the part has been chosen as the sketch plane.
  • Operation performed on the sketch: Cutout > Revolve..
  • The rotation angle is 360 degrees, which is a full circle.

Example: Revolve a sketch into a hollow shaft

  • Operation performed on the sketch: Boss > Revolve
  • The rotation angle is 360 degrees, which is a full circle.
