How to create an arch with bridge edge loops consistently I am trying to create an arch.  I followed the instructions from 2:49 time at How to use Array to build an arch - Blender 2.8 Tutorial and got it to work, but then after that, it failed to work again producing an S shape rather than a curve.

It is quite frustrating.  I've been doing it over and over and am unable to figure out how I am mucking it up. The answer provided on this site for how-to-use-bridge-edge-loop-to-create-arch did not seem to apply to my issue.

The most aggravating thing is that I can make it work once in a while but not consistently, so it's got to be something simple.

Thanks in advance!
Edit: This is now a confirmed bug: Bridge Edge Loops operation has inconsistent results



You need to duplicate the objects in Object Mode and join them.
Duplicating them in Edit Mode gives weird results.

Duplicated in Object mode and joined. Works as expected.
