// case of getFacade() returning a unique_ptr to GeometryFacade in GeometryFacade, and one to ExternalGeometryFacade. I have not managed to

// find a good solution to this problem, thus the code duplication.

|
|
// Summary Remarks:
|
|
// It is intended to have a separate type (not being a Geometry type).
|
|
// it is intended to have the relevant interface in full for the sketcher extension only
|
|
// It is intended to work on borrowed memory allocation.
