When creating a revolution, the '''Revolution parameters''' |
When creating a revolution, or after double-clicking an existing revolution in the [[Tree_view|Tree view]], the '''Revolution parameters''' task panel is shown. It offers the following settings: |

Type offers five different ways of specifying the angle of the revolution: |
|||
====Dimension==== <!--T:38--> |
|||
<!--T:39--> |

Enter a numeric value for the '''Angle''' of the revolution. With the option '''Symmetric to plane''' the revolution will extend half the given angle to either side of the sketch or face. |

<!--T:41--> |

The revolution will extend up to the last face of the support it encounters in its direction. If there is no support, an error message will appear. |

====To first==== <!--T:42--> |

<!--T:43--> |

The revolution will extend up to the first face of the support it encounters in its direction. If there is no support, an error message will appear. |

Description
The Revolution tool creates a solid by revolving a selected sketch or 2D object about a given axis.
Above: sketch (A) is revolved 270 degrees counter-clockwise around axis (B); resulting solid (C) is shown right.
Usage
- Select a single sketch or one or more faces from the Body.
- Press the Revolution button.
- Set the Revolution parameters, see Options below.
- Press the OK button.
Options
When creating a revolution, or after double-clicking an existing revolution in the Tree view, the Revolution parameters task panel is shown. It offers the following settings:
Type
Type offers five different ways of specifying the angle of the revolution:
Dimension
Enter a numeric value for the Angle of the revolution. With the option Symmetric to plane the revolution will extend half the given angle to either side of the sketch or face.
To last
The revolution will extend up to the last face of the support it encounters in its direction. If there is no support, an error message will appear.
To first
The revolution will extend up to the first face of the support it encounters in its direction. If there is no support, an error message will appear.
Up to face
The revolution will extend up to a face. Press the Face button and select a face or a datum plane from the Body.
Two dimensions
This allows to enter a second angle in which the revolution should extend in the opposite direction. The directions can be switched by checking the Reversed option.
Axis
Specifies the axis of the revolution:
- Vertical sketch axis: selects the vertical sketch axis.
- Horizontal sketch axis: selects the horizontal sketch axis.
- Construction line: selects a construction line from the sketch used by the revolution. The dropdown list will contain an entry for each construction line. The first construction line will be labelled Construction line 1.
- Base (X/Y/Z) axis: selects the X, Y or Z axis of the Body's origin.
- Select reference...: allows the selection of a straight edge or a datum line from the Body.
Note that when changing the axis, the Reversed option may be (un)checked automatically.
Angle
Defines the angle of the revolution. This option is only available if Type is Dimension or Two dimensions. Angles larger than 360° are not possible. Nor are negative values, use the Reversed option instead.
Symmetric to plane
Check this option to extend the revolution half the given angle to either side of the sketch or face. This option is only available if Type is Dimension.
Reversed
Reverses the direction of the revolution.
2nd angle
Defines the angle of the revolution in the opposite direction. This option is only available if Type is Two dimensions and Angle is smaller than 360°.

Notes

- When using a SubShapeBinder for the profile, selecting the binder in the Tree view will fail, instead the binder's face has to selected in the 3D view.
