sketch mirror issues

[Anonymous]

Just wanted to see if anyone else has had this issue or if i'm doing something wrong. 

If i select 2 squares at -50mm and mirror them to +50mm they're not exact. They end up 50.052 or something like that which throws the whole design out if i don't realise it's happened. Is this issue to do with the mirror reference line not being exact or am i missing something? Also, is there any way to mirror without leaving a link to the original geometry to be able to edit independently of the original rather then edit the original to edit all copies?

cheers.

You are missing logic.

I have not experienced the change in size of a fully constrained sketch so I cannot comment on that.  You can however break the link between the original sketch and a mirror of it by deleting the required symmetrical sketch constraints added during the mirror operation.  This is a manual process as there is no switch to select in the mirror dialog box.  In my Screencast I mirror a rectangle and then delete a couple of the symmetrical sketch constraints to demo.
