PartDesign Mirrored

Introduction
'Mirror features' - This tool takes a set of one selected features as its input (the 'original'), and produces with it a second set of features mirrored on a plane. For example:

Use

Mirror Plane Selection
When creating a mirrored feature, the 'Mirrored parameters' dialogue offers four different ways of specifying the mirror line or plane.

Horizontal sketch axis
Uses the horizontal axis of the sketch as the axis of symmetry.

Vertical sketch axis
Uses the vertical axis of the sketch as the axis of symmetry.

Select reference...
Allows you to select a plane (such as a face of an object) to use as a mirror plane.

Custom Sketch Axis
If the sketch which defines the feature to be mirrored also contains a construction line (or lines), then the drop down list will contain one custom sketch axis for each construction line. The first construction line will be labelled 'Sketch axis 0'.

Preview
The mirror result can be previewed in real time before clicking OK by checking "Update view".

Limitations

 * Currently, only the last feature in the feature tree can be chosen as the 'original' therefore,
 * it is not possible to choose more than one feature to be mirrored
 * it is not possible to select more features to add to the list view of 'originals'
 * Once the Mirrored feature has been started or been completed, it is not possible to replace the original feature for a different one.
