    Smoothly connects a series of selected Curves with a bezier mesh.
    ###
    Usage:
    Activate the Tool and follow the prompts.
    Select Curves in order [at least 2 are required].
    Each selected Curve is color-coded ROYGBIV as it's picked.
    You may NOT re-select the same Curve again unless it is the first one
    that you selected [Red] and there are at least two curves already
    highlighted.
    If you do re-select this first curve then the mesh might loop into a
    weird convoluted 'doughnut' !

    Double-Click or Press <Enter> to complete the selection of the Curves.

    You are now prompted for the Number of Mesh Segments between each pair
    of Curves - the initial value is based on the maximum number of
    segments found in the Curve set.
    Press OK to accept this value, or enter a new value [>0] and press OK,
    or press Cancel to stop the operation.

    The mesh is made with 'bezier' linking forms, and faces oriented.

    You are then prompted Yes/No to:
    To Reverse the Faces.
    Quad Faces
    Smooth the Mesh.
    Erase the Originally Selected Curves.

    Curves can have unequal number of segments - although keeping their
    segmentation the same or in simple multipes can give 'smoother' forms.
    The Curves in a 'set' can be looped or open-ended as desired.
    All open-ended or all looped sets should give consistent results.
    Mixing looped and open-ended curves in the same 'set' might give
    unexpected effects.
    It's recommended that you split loops in any mixed sets with a short
    piece of line drawn to 'force' a combined start-point/end-point...
    The tool attempts to loft curves end_to_end without twisting -
    however, some combinations of curves might benefit from having one
    curve 'reversed' - if so explode it and then re-weld, or try edit-cut/
    paste_in_place...

Hi Solo,
the debabelizer is in the Zip.
Just in case, here it is (put it in Plugins folder)

You make a plug by a day! :o
That is a good average :D ;)

PS An automatic order Selection curves will be fine for exemple in case of use plug like Grow by TIG? ;)

Super! Thank you TIG so much!
Though it skips segments in the very first try.

Without the skp to try I'm unsure what's up...
Are the curves continuous - it would help it they had the same number of segments [although that IS meant to be coped with].
Can you post [or PM me] a skp displaying this glitch ?

I've tested your skp and I agree that the tool has a glitch - for some reason it's missing out a part of the mesh in the latter/earlier stages - the two versions I first illustrate below are by picking the curves in their reverse order - different bits get missed out...
The original has curves with varying edge counts...
In the 'copy' I edited the curves so each has 12 edges [or 24 for the S one] - to make them readily sub-dividable - now it works fine - so it must be a bug in the re-division of the edges to try and get them to match each other - also used in EEbyRails incidentally
I'll debug and get back to you...
In the meanwhile please use curves with more closely related edge counts - they will work... any number SHOULD work...

I see that the problem is that the 6-segment zigzag is being divided into pieces of four to match the 24-segment S-curve BUT at one point it's becoming 1 piece short [3] and at another one too many [5] so that the 'apportionment' of the edges goes wrong and it fails - so at least I have the effect... but now to find the cause :roll:

And what logically follows in the ExtrudeTools collection?
It was inevitable. Thank you, TIG

TIG:
What would it take to make the resultant mesh into a Bezier mesh? Or am I talking about another tool?
In other words after generating the mesh, you could modify it by Bezier control points that would allow you to pull and stretch the mesh like a rubber sheet, and even unfold some unwanted contortions.

Thomthom is working on a Vertex-Editor. which I think would become the basis of this editing tool ?

UNREAL!!!!!! You are the man TIG!!!! :thumb: :thumb: :sketchstatic:

I'm starting really wish you would take these algorithms and write a new plugin to handle making terrains similar to "From Contours" but without the rats nest of a mesh the native tool creates. Your meshes are so smooth. Google needs you on staff immediately with a nice fat salary so you can code to your hearts content!

I don't know if this is another Mac peculiarity but I get very strange results. From three circles (two copies plus an original), when I would expect a cylinder to result, I get this:-

I attach the skp file just in case there is something weird lurking in it.
