Add switch - "leave only mirror", when "transform body"

Feature request. Removing the 'Bughunt' from the title. Also, I believe this functionality is possible currently. I have fully tried it but you should be able to create an App::Link to the original part. Then set the scale to -1 and adjust the scale list to control which direction to scale along. The result should be the link being mirrored.

This "way" is very roundabout. As I understand it, it is quite simple to delete the "basic solid" (when the switch is on - "leave only mirror")

[sliptonic]

The workaround isn't ideal but AFAIK, it does achieve the goal.
We have to prioritize where we spend development effort. I've left the issue open and noted that it's a feature request. IMHO, if the goal can be achieved in some other way, then making a new feature to do it easier should be lower priority. Of course, if someone wants to implement it, a contribution would be gladly accepted ;-)

Thank you. I realized. src/Mod/PartDesign/App/FeatureMirrored.cpp It seems to me that blocking one line from the list (when the switch is on) will solve the problem very easily. Although maybe I'm wrong. On a previous project, I took an almost similar "workaround" and got an error embodied in metal.
