SOLIDWORKS has a cool feature that can be used to mirror the drawing view without the need of mirroring the reference part:.
All projected and linked views are then updated based on the mirrored drawing view.
To mirror a drawing view:
- Select the drawing view.
- Expand the "Mirror" option in drawing view properties.
- Check the option "Mirror view" and choose whether you want to mirror a drawing view horizontally or vertically.
All the dimensions and annotations will keep their position after the mirroring.
