[[Image:partdesign_revolution_parameters.png|frame|left]]

===Type===

{{Version|1.0}}

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 {{Button|Face}} button and select a face or a [[PartDesign_Plane|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 [[PartDesign_Line|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===

{{Version|1.0}}

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°.

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

  1. Select a single sketch or one or more faces from the Body.
  2. Press the Revolution button.
  3. Set the Revolution parameters, see Options below.
  4. 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

introduced in version 1.0

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

introduced in version 1.0

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°.
