To produce a Mirror Image in the Main Menu select Operations - > Transformation - > Mirror Image
This operation creates a symmetrical copy of an Object, which can be mirrored in three different ways. Create a copy checkbox allows to keep the initial object, otherwise it will be removed.
The Result will be a GEOM_Object.
Firstly an Object can be mirrored through a Plane of symmetry
TUI Command: geompy.MakeMirrorByPlane(Shape, Plane),
Arguments: Name + 1 shape + 1 plane
Secondly an Object can be mirrored through an Axis of symmetry
TUI Command: geompy.MakeMirrorByAxis(Object, Axis)
Arguments: Name + 1 shape + 1 vector.
Finally an Object can be mirrored through a Point of symmetry
TUI Command: geompy.MakeMirrorByPoint(Object, Point)
Arguments: Name + 1 shape + 1 vertex.
Our TUI Scripts provide you with useful examples of the use of Transformation Operations.
