Question [World Edit] Flip/Mirror diagonal

Yoo guys,
I have a little problem.. So this is what I have :


And I want this :



Any ideas ?

 

if you copy a selection, and do //rotate 90 it will rotate your clipboard 90 degrees and then when you do //paste it will paste it, but rotated. (90 can be replaced with any number for the amount of degrees you want it rotated. such as 90 or 180)

 

Yeah, I know that, and that's not what I want ^^'
(Not rotate, I want flip/mirror, don't know if it's possible.. :s)

 

I summon the master of WorldEdit ! Oooh- master come help me ! ༼ つ ◕_◕ ༽つ

 

Err, I don't think you could flip like that since it's a square selection and would replace the original piece with air.

 

This is possible with some
-- clever selections
-- the right flip axis
-- a rotation of that
-- and pasting back with the -a option (which ignores the air blocks in the paste, not overwriting the original

I'm attempting to enumerate the exact steps for your example right now

 

Didn't know you could do that!

 

Here is my step-by-step reproducible method using your pattern, but with clay blocks instead of stone for visibility purposes. I have added some blue and orange wool blobs for orientation-reference, and added a white clay block for reference purposes exactly 1 block diagonally out from the design.

Select the entire volume defined by the green posts ie, where the marks in pink are, and then stand on the white clay spot.

Do //copy
Standing in place still, look towards the orange wool direction (on the cardinal axis ) and

do //flip
do //paste

That gives you this arrangement:



Now, select the entire region defined by the green posts for this new version, ie, the marks in pink..
Then return back to stand on the white clay block
do //copy
do //rotate 270
do //paste

That gives you this arrangment:

Now select the entire region for this third one defined by the green posts, ie, the marks in pink...
Then stand on the white wool block location - its 1 diagonally out from the green post, same way the white-clay in the original was.
do //copy

Now go stand on the white clay block position
do //paste -a

And voila:


----------
Then some cleanup is required afterwards...

As with all complex WE jobs, the CRITICAL parts are the identification of the reference location for your commands, - the white-clay block in this example, and the white-wool block later, and to look straight east/north/south/west lines doing the //flip command


You dont have to do everything in the space beside this starting unit - you can do the initial region copy and flip, then fly high in the sky or to a different world, or a hill to the side - but place some kind of reference block to stand on paste the flipped clipboard. You can then do the select/copy/rotate/paste of this second unit in the remote area as well, since you have that same reference point to stand on... then, find/make the white-wool reference point to copy the third unit , and you can now fly back down to the original unit to //paste -a

 

@Boomer
This looks nice ! I gonna test it soon and tell you what I did !

EDIT:
Here it comes ! It worked. Thank you so much to all of you, specially Boomer)
