I'm looking at making a pipeline for building geometry sitting on the inside of a cylinder. Think space game stuff on the inside of an O'Neill cylinder or a smaller space station. I was planning on using the bend modifier to get the "three point perspective look" on geometry to help visualize how I should be building geometry and such.

For the life of me I can't figure out how to properly control the fuckin gizmos on this thing. No matter what I do, I cant seem to figure out what Autodesk was thinking when they coded this thing.

Rotating the gismo allows me to properly control the direction things bend.
Scaling the gizmo box doesn't seem to have any directly related effect. Scaling the gizmo under the -360 angle bend to where the geometry is the desired size shows that the box isn't the same size as the plane when at a zero angle bend.
I no longer have any idea what the center gizmo is.

Anyone have a clue how this thing actually works? I'll end up with a maxscript tool to deform regular geometry based on the radius of the cylinder it's going in if I can figure this out.
