Control of layers (Bring to Front / Send back) Floor Plan

[Paul Herber]

Try this ..
Select all the arrows (just select the first one, then control and click to add more) menu Format -> Layer
create a new layer called Arrows
All your arrow shapes should now be on this layer.
Now you can do as wapperdude says with the Edit -> Select by Type
and select the appropriate layer. Then menu Shape -> Bring to Front.
That seems to work.

Thanks Paul, I should have been more precise in my answer.

I've created an add-on that can help with this problem
I call it Mezzo - Maintain Z-Order

It can be used to keep any number of shapes at the front of a diagram, any number of pages.
