Are the windows not mirrored based on the line?
It is possible to use the mirror as the reference point for the wall, but why does the window have only one reference point?

[Barry Kelly]

Windows and doors can only be mirrored within the same wall.

You can not mirror from one wall to another.

You must mirror the entire wall with the window if you want to do that.

Or copy the settings of the window (ALT+click (Pipette)) and then just place a new window in the other wall.

Thank you for always. ^^

This part seems to be quite difficult for Rabbit, who habitually copy and use, or for Koreans who use CAD.
There is no problem for someone trying to adapt like me, but...
