mirror a part with tree working

[Tarkus]

Hello everyone,
as from title, I have to get a mirrored copy of a part and maintain the working tree.
therefore the normal derivation operation is not good.
Any ideas?

once I mirrored all the work within the part itself and then "cancellated" with a negative extrusion the original part because I wanted a symmetrical part to an existing editable independently. . .
if I don't remember badly I used the plans as a base, taking care that dx and sx did not intersect, so a plan was placed "side", outside the model, if I can explain myself.

but it worked. . .

shape from the beginning according to the mirroring.
I know that it seems trivial but I do so, at the cost of canceling some work and doing it properly or moving it into the working tree.
we all know how much it commits to the table and what it means not to recover the right one to make the left.

finding me after a long time in the need to do as required in the discussion with a badly shaped part I learned to follow my own advice but... wonder! I discovered something new, that is:

from the control mirrors in the area part by selecting solid mirror instead of the usual working mirrors change the selections available and at the bottom of the form the "remove original": then in two clicks you have the only mirrored part without "turning" all the work.

How beautiful!

I knew, but it was something I wanted to avoid, it's probably my fist, but I wanted a mirrored file yes, but for the rest identical to the first.
solved by the old method: remake as a leader.

but the so-called explicit cad, how do they behave in these cases?
