Re-ordering with 'Send to Back' and 'Rebuild All' works for me.
As a work around, could you draw the polys such that they don't overlap?
I'm pretty sure that I read there is not a dialog box to control the priorities and it doesn't appear that clicking send to back or bring to front has any real affect. So, what does control the priority?
I have 3 pours on my ground layer and sometimes when I hit rebuild all I get all three and sometimes I only get 2 because the big one is poured first. I guess I could manually route the big on around the little one but that seems unnecessary.
The fact that I keep having to move the big one out of the way and re-pour the little ones first is causing anxiety.
