[Tutorial > Modeling] How to Model a Horn Shape

[eugenesr]

Great tutorial - it got me to thinking and this is what I came up with. Just a different way to peel the orange. (I would have used "skin the cat" but I didn't want to get PETA on my case - <grin>)

Enjoy - and thanks for all you your help. I've learned a great deal in the past two weeks with Sketchup.

Hi Eugene, hi folks.

If you use an arc with 9 segments, you get 10 cross sections.

The scale factors will then be : 1.0, 0.9, 0.8, 0.7, ..., 0.2, 0.1 and 0.0.

SU will not accept a scale factor of 0 and since the last section shall terminate with a point, it shall be a real cone.

By the way, there are at least three methods that come to my mind to make a real cone. See attached SU file for ideas.

Nice tut...as always...Jean. Like many such tutorials, it's not just a question of solving that particular problem, but equally an indication of the kind of strategy that can be used to tackle a much wider range of design problems.

For anyone on a PC, needing more complex horn shapes and spirals, there is a great little Freebie called Spiralizer at http://www.armanisoft.ch/webdesign/FrmDownloads.html
There is an English link at the top of the page.
Armanisoft also offer a 3D text freebie called Elefont, but now that SU has that feature built-in it has become somewhat redundant.

I've used a different technique, also using 'scale' factors:

Anyone else have another way to "skin this cat?" I've found that new methods for achieving a desired objective are always appreciated by the Community.

Well, not another "method", but there's [CASF[FunShapes.rb in the Ruby Library Depot with which you can quickly create (among others) horns, too.

Yes, I know that it is first of all essential for someone to be able to model it rather than use plugins but when you are lazy (or in a rush...)
