It creates a `Part::Mirroring` object from the given `objlist` using

Parameters
|
|
----------
|
|
objlist: single object or a list of objects
|
|
A single object or a list of objects.
|

|
|
p1: Base::Vector3
|
|
Point 1 of the mirror plane. It is also used as the `Placement.Base`

|
of the resulting object.

|
|
|
p2: Base::Vector3
|
|
Point 2 of the mirror plane.

Returns
|
|
-------
|
|
None

|
|
|
|
list
|
|
List of `Part::Mirroring` objects, or a single one

|

|
|
|
|
To Do
|
|
-----
|
|
Implement a mirror tool specific to the workbench that does not
|
|
just use `Part::Mirroring`. It should create a derived object,
|
|
that is, it should work similar to `Draft.offset`.
