Creating Revolved Surfaces

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

Open the Revolution1.CATPart document.

1. Click Revolve .

   The Revolution Surface Definition dialog box appears.

2. Select the Profile and a line indicating the desired Revolution axis.

3. 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.
   Note: Wires cannot be selected as an up-to element

4. Click OK to create the surface.

   The surface (identified as Revolute.xxx) is added to the specification tree.
   	There must be no intersection between the axis and the profile. However, if the result is topologically consistent, the surface will still be created. 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. Parameters can be edited in the 3D geometry. To have further information, refer to the Editing Parameters chapter.
