Plugin Help How to use WorldEdit 'convex'

Hi!
I post this message to request your help.

In my server i want to delimit houses outlines.
So, to do this, i use '//sel convex', because '//sel poly' selects blocks above the roof...

But, i've a problem, when i try to register this selection to a WorldGuard region.
(with '/region create maison_1') it says: "Please select an area first. Use WorldEdit to make a selection!".

If you have a solution, it will be great!
Thanks for reading.

(Sorry if there's some spelling mistakes, i'm french... xD)

 

@Airwaito When you did //sel convex, did you select anything with the Wooden Axe?

 

Yeah.
I select all my points with the Wooden Axe.

EDIT: When I try to do a //expand 5 down.
It says: "0 blocks expanded". >.<

 

@Airwaito I don't think you can expand with convex selections?

 

'kay.. ^^
So, how can I register my selection as a Worldguard's region?

If I make a polygonal selection, there's no errors.
But this is not the case with convex... :?

 

@Airwaito I don't think WorldGuard supports convex... But I could be wrong.

 

WorldGuard region supports only cuboid and polygonals...
I'll check for another solution. ^^
