Dear Dorin! Thanks for your detailed reply.

This plugin link is ok.

https://sourceforge ...

I could make the mirror function to resize option changing width or length to a negative value. example: width=440 / width=-440
This is right or is a shortcut?

Thanks

Dear Dorin, thanks for your reply.

I have installed plugin AdvancedEditing.sh3dp, but I do not have mirror icon in somewhere on toolbar, only icon rotate and resize on edit toolbar.

The plugin AdvancedEditing.sh3dp is right for mirror copy?
Thanks!

Estimados, Estuve revisando los plugin y no encuentro la manera de copiar y pegar en espejo (mirrow copy).
Existe algun plugin que no he visto?
Gracias.

Dear, I was reviewing the plugin and can not find a way to copy and paste into mirror (mirrow copy).
Is there any plugin for this?
Thanks.
