how would fpe screw over grid definitions? wouldnt it be easy enough to check if they conform to the brick grid?
Because even though a mesh appears to be Blender grid aligned, a vertex could still have a coordinates such as 1.00000000012 which could cause it to be out of bounds if on the edge of the brick. The rounding helps get rid of such errors. I don't see the issue here?
Actually reading your original post again, did you mean that I use the raw unrounded vertex coordinates when checking for out of bounds? This is not correct, the vertex coordinates and bounds coordinates are rounded when doing this check for brick grid objects. Can you paste the log lines of this error you're getting?
I've fixed the issue with brick grid + another one. Waiting on more info on this rounding problem before releasing a new version because I can't replicate it. Install the
develop branch if you want the fixes ASAP.
Edit: Saw your edit Conan, looking into it.
