PartDesign Revolution

Description
The Revolution tool creates a solid by revolving a selected sketch or 2D object about a given axis.



Usage

 * 1) Select the sketch to be revolved.  A face on the existing solid can alternatively be used.
 * 2) Press the  button.
 * 3) Set the Revolution parameters (see next section).
 * 4) Press.

Options
When creating a revolution, the Revolution parameters dialogue offers several parameters specifying how the sketch should be revolved.

Axis
This option specifies the axis about which the sketch is to be revolved.
 * Vertical sketch axis: selects the vertical sketch axis.
 * Horizontal sketch axis: selects the horizontal sketch axis.
 * Sketch axis: selects a construction line contained in the sketch used by the Revolution. The first construction line created in the sketch will be labelled Sketch axis 0. The drop down list will contain one custom sketch axis for each construction line.
 * Construction line: selects a construction line contained in the sketch used by the Revolution. The drop down list will contain an entry for each construction line. The first construction line created in the sketch 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 selection in the 3D view of an edge on the Body, or a datum line.

Angle
This controls the angle through which the revolution is to be formed, e.g. 360° would be a full, contiguous revolution. The images in the examples section demonstrate some of the possibilities with specifying different angles. It is not possible to specify negative angles (use the Reversed option instead) or angles greater than 360°.

Symmetric to plane
If checked, the revolution will extend half of the specified angle in both directions from the sketch plane.

Reversed
If checked, the direction of revolution is reversed from default clockwise to counterclockwise.

Properties
Below are properties which can be defined after creation of the feature. Data properties Base and Axis are uneditable.


 * : angle of rotation. See Angle.
 * : label given to the operation, can be changed at convenience.
 * : true or false. See Symmetric to plane.
 * : true or false. See Reversed.
 * : true or false. If set to true, cleans the solid from residual edges left by features. See Part RefineShape for more details.
