Hello DannyT,

I've made some experiments with the flow command. And it looks like that it works (I don't really checked it allready) . The important point is how the target surface is created. I've made it with the sweep with two arcs as rails (so it works only with truncated???- sorry about my english). So the U_V-parameters of the cone should be mapped to this targed.

Kind regards
Karsten



p.s.:Great software!!!

Cool Flow method! ;)
But Original Cone's edge is 13.4164079
Plan cone's Edge unwrap result is 13.4100000
Does this acceptable ?

I am always amazed that tools are named "French curves"! Have you some some info about that ?
In France we name these tool "Pistolet" (pistol, gun in English) or "Perroquet" (parot in English)

@ Burr, great method! nice video demo dude.
I'm still laughing when you said "I can't really follow that stuff, I've lost my mind"

Cheers

Hi Karsten,

> I've made some experiments with the flow command.

I like your method with flow it's very close.

Cheers

Hi Pilou,

> I am always amazed that tools are named "French curves"!

That's what us English speaking Designers and Draughtsmen have always known them as http://en.wikipedia.org/wiki/French_curve.

There are flexible curves as well, which came later http://tinyurl.com/pzdbm2t

Cheers

Yes but I never find something about this curious origin of this particular name! :)
maybe the snail'shell curvature ? :)
A big mystery for me! :)

In Italy we call it -Curvilineo-
This tool to draw curves was used by taylors from long,long time



Actually they are still using to make or modify models or create shapes and angles of the body
There is a French curve (Curvilineo spalla-shoulder) to make upper part of the body(holes for neck,arms and belly)
there is also a Hip curve (Curvilineo fianchi-hips) to make lower part of the body (skirts,trousers)
Maybe...i say maybe...this taylor's tool was called French curves like a tribute to France..being,in the past,wordwide reference of fashion
Pardon monsieur Pilou,but nowadays references of fashion are changed,so.....we could call it "Italian curve" ;) :) :)

Maybe a cool explanation! :)
But want some proof of that!

else some italian curves ;)

From
George L. Legendre’s book, Pasta by Design, provides the gourmet geometry behind a wide range of different pasta shapes from across Italy.
You’ll never look at Spaghetti Bolognese the same way again.

@Danny,
""""""I'm still laughing""""""""
:)


Thanks, that method is a result of a discussion here with Miguel Gibseone.......

@Pilou:

But want some proof of that!

-----------------------------

That was just my deduction :) ..no proof...

about Italian curves:
..i don't want to start again the eternal discussion between you and us about who is best to make wine,cheese,fashion... :)

here an example of mathematic and design to create a new shape of pasta by one of the best Italian designers:Giorgetto Giugiaro !





This is also a quick introduction to Giugiaro,better known as car-designer
I'm just modeling his classic piece that i'll post soon here
Au revoir ;)

Oops, Frustum is the correct spelling.
Michael, can you correct the spelling in the Subject?

A script for unwrapping a cone, or a conical frustum, with the top cut off parallel to the base, is attached.

Implementation of the checkbox for Frustum, versus Cone, is a bit Clunky.
Is there a better way to the checkbox, to change the selection from frustum top circle, to cone apex?
I tried hard with code from Flow, but did not succeed in making a better interface for the checkbox.

A test 3dm of a frustum and a cone is included.

@Mauro
Appetizing!

Maybe you know this very elaborated French pasta by Stark ? ;)

I knew Philippe Stark did a new pasta shape but,like his colleague Giugiaro,without success...
people here buy classic ones:

"spaghetti's family"



"short pasta"



all these,most common are:Spaghetti-Rigatoni-Fusilli-Farfalle
they join well with four classic sauces:
Burro & Salvia (melted butter and sage leaves cooked together)
Pesto (Basel leaves+garlic+Parmigiano cheese+extra-virgin olive oil+pine nuts,all fresh,smashed together)
Ragu'..best known outside as Bolognese (ground meat and tomato sauce cooked together)
Carbonara (fresh eggs+little bacon cubes+pepper quickly cooked together)

-------------

My apologizes to Brian and Burr for this "gourmand" off-topic :)

non la prego di accettare le mie scuse for me.

That's the way to use the ole noodle!

..si figuri signor Burr....non c'è di che'.... :)
(..means in a kind way:you don't need to say excuse me)

Thanks for this pasta encyclopedia! :)

PS Seems the Stark form is an avatar of this! :)

Solved the camoflaged cone mystery.
Seems a second cone was hiding underneath.




Currently working on conical pasta from a Logarithmic2D script ceiling projection :-)

(And unwrap of a curve on a cone, using object list of lots of points.)

Here is an update to the ConeUnwrap script, which works on circular cones with axis perpendicular to the base.
It uses two buttons to select cone with apex vs conical frustum. (Using Michaels method in History command.)
Also the frustum unwrap line segments were redone, so the Unwrap is Sweep ready. (Do NOT use planar, as UV isocurve would likely not match.)
The script appears to work just fine under MoI4Dec2017beta.

I typed up some documentation which might be nice in a wiki...
A couple of remarks: Holes in the cone, or bites out of the cone, or curves on the cone, can be unwrapped using Flow, with the cone face and unwrap Sweep face.
Also, in the event the holes disrupt the base circle, slantseam, or top circle, substitutes can be created by the user, or use a substitute intact cone or frustum.


Edit 1/1/2018, Corrected 2 "bugs" in the script. New version is here: (post 33)

Thanks a lot !
Work fine also under MoI V3

Hello Brian,

thanks for improving the script!

Have a nice day
Karsten
