very nice!
Interesting concept to control the bevel object, perhaps this will be implemented via modal.
Reminds me of one of the Windows 98’s screen saver.
This looks great! Any chance that they could fill a predefined volume? Instead of just being a square you could route pipes through a complicated passage way by extruding a simple cube into that space, then the pipes would generate inside that object.
Lots of fun but I hung Blender by dialing in to small a value for Length Y: min (with Pipes: 16). I guess its making to many divisions? If there are values that could make ridiculous amounts of geometry perhaps there should be a warning or preset value the slider won’t go past unless you type in a number?
Select curves, run the script. It uses Simple Curve addon. Set Bevel Size to 0 when creating nightmare pipes.
import bpy
for obj in bpy.context.selected_objects:
bpy.context.scene.objects.active = obj
bpy.ops.object.mode_set(mode = 'EDIT')
bpy.ops.curve.select_all(action='SELECT')
bpy.ops.curve.spline_type_set(type='BEZIER')
bpy.ops.curve.bezier_points_fillet(Fillet_radius=0.1, Fillet_Type='Round')
bpy.ops.object.mode_set(mode = 'OBJECT')
Deforming options are slated for 0.9.
Nice work around, the upcoming subdivision options will incorporate beveled corners.

I am thinking of adding a soft limit to these values, keep in mind this is still beta.
Of course, I love being a beta tester 
Is this addon still in development? (I keep checking 
I love this addon quite a bit).
Improvements are slated in to be implemented right after I release the name-panel rewrite here soon.
How should I unify these pipes under one object? I’m looking to export it as an FBX for my game engine and don’t know how to make it a game ready asset. Any advice would be appreciated.
I keep checking on this addon. It’s a brilliant idea but It’s been quite some time. I see so much potential here!
One Idea I’d love to see, is to have the nest of pipes connect between any two selected bodies of faces. This would be useful and awesome. I think I will dive into the script myself and see what I can do.
Since proxe seems busy with other addons I took the liberty of porting it to 2.80.

The addon is really neat, thank you. But it would be even better if the pipes were created inside a collection.
Thx, cool…
The pipes appear, but I can’t play with the parameters, it’s like it was grayed ?
test on today build…
This is great. Thx for sharing.
