Revolve
This is a special case of using the Extrude option. Revolve rotates a polyline about an arbitrary axis to generate a surface or volume.
- Select the Geometry
workflow tab. - Select at least one polyline.
- Select the Revolve
option from the Extrude/Sweep/Loft Tools sub-menu in the Geometry menu. - A dialog should appear. You can use the Add Curve or Delete Selected Curves to add or remove polylines to be used in the revolve operation. The order does not matter.
- Define the axis of rotation in the Revolve Around section. You can select the x, y or z-axis or a Custom axis defined by entering two points. You can also use the Choose option to select your axis based on:
- An existing edge
- Two existing points
- An existing plane to get a normal or
- Three existing points that form a plane.
- Define the following in the Parameters section:
- Start Angle: Offset angle about the rotation axis before you begin revolving by the Delta Angle. Angles are measured positively clockwise about the rotation axis. A zero start angle refers to the original start position of the polyline, with no rotation.
- Delta Angle: The angle change about the rotation axis applied to the polylines after the start angle.
- Slices: The number of polygon segments that are generated between the start and end position of the rotated polyline to generate a surface or volume.
- Tolerance: An advanced feature to determine the accuracy of the rotation for complex polylines. For the majority of cases, you can leave this as the default value.
- You can use the Preview
option to view your revolved entities before you accept the changes by pressing OK.
