Creating Revolved Volumes

This task shows how to create a volume by revolving a planar profile about an axis.

Open the RevolutionVolume1.CATPart document.

 

  1. Click Volume Revolve .

    The Revolve Volume Definition dialog box appears.
  2. Select the Profile.

    • The profile must be planar and closed or closed on the axis of the sketch.
    • There must be no intersection between the axis and the profile. However, if the result is topologically consistent, the volume will still be created.
    • The profile must not be perpendicular to the revolution axis.
    • If the profile is a sketch containing an axis, the latter is selected by default as the revolution axis. You can select another revolution axis simply by selecting a new line.
  3. Select a line indicating the desired Revolution axis.

    It can be a line or the axis of a sketch.
  4. For Limit 1 and Limit 2, specify the limit types of the revolution.
    Dimension: Enter angle values or use the graphic handles to define the start and end limits of the revolving profile.

    Up-to element: Select a geometric element. It can be a point, a plane, or a surface. If a point is specified, the up-to element is the plane normal to the revolution direction passing through the given point.
    In the angle box, enter a value to define an angular offset from the selected up-to element.
    Notes:
    • The up-to element can intersect the profile and the volume to be revolved. In the latter case, it must completely cut the volume and there should not be any partial intersections of the up-to element with the volume. If you select two up-to elements, they must not cut each other within the volume to be revolved.
    • Wires cannot be selected as up-to element.

    In the example, one side of the revolution volume is limited by the point.
  5. Click OK to create the volume.

    The volume (identified as Volume Revolve.xxx) is added to the specification tree.
