Football Panels
-
I'm try to create a rugby ball(same basic shape as an american football) in sketchup, I can make the basic egg shape no problem, but am having trouble making panels. I don't just want a perfect rounded shape, as there are indentations where the seams are and that's what I'm trying to recreate.
My idea was to create 1/4 of the ball, bevel the edges and copy it and put them together. trouble is I don't know how, or if you're to bevel the edges on a curved surface like that. Any ideas or tips/?

John,
Can you post what you have already? that will make it easier to help.
BTW, welcome to SCF.
-
here's what I got so far.
-
This is what you want right? (excuse ralph lauren ball, but it was first image I found that looks like what you need).
The indentations are the 'ribs'?
-
yes exactly
-
Can you post your model?
-
do you mean the sketch up file, or what I'm trying to model it after? I'll attach the .skp file anyway
-

I had an idea without plug-ins but my SU just crashed, I'll have to give it another try
-
thanks solo, how did u get everything so smooth?
-
a plugin called Artisan. (put in search)
Hope you succeed.
(off to bed almost 3am here)

I'm sure ill get there, thanks for the help

Surprisingly tricky for something so simple. You can probably do some of this with Rubies, but I couldn't be bothered trying to work out which ones...so I just did it by hand.
-
Of course, the easy way would be to just lathe the basic shape, then apply a texture, using the spherical map setting in the UV Tools ruby.
-
A simple way to make a rugby ball would be to lathe the profile/curve a quarter circle.
Then extrude each end/inside face a few mms.
Then scale that face towards the center, once top/bottom and once outside towards center - about .98?
Then you make it a component and rotate/copy 3 copies.
A little tweaking and smoothing and you're done
Another way would be to use Joint Push Pull tool.
Curviloft, Artisan, Amorph are all plugins that could be used here. -

OK, just how did you do the crease without a plugin?

Without PlugIn, I created the quarter sphere, Made it longer in one direction, then resized just the 2 flat faces remaining (leaving the corner untouched) and copied it 3 times around that corner ...
Exagerated, this is one result

hd, I routinely leave creases in all my people and other organic stuff...mostly to delineate muscle groups, facial features, knuckles etc.
The football was easier as it's a more regular shape. I used the smoothing slider just enough to smooth the panels, but not enough to smooth the seams. Then I turned off hidden geometry and rectangular selected the whole thing (as opposed to triple-clicking it). This selected all the smoothed faces as a single surface, plus all the yet unsmoothed seam lines. I then used the smooth dialog again...but with both boxes unchecked...turning it up until all the seam lines disappeared.
They disappear but don't smooth (because the normals box is unchecked)...hence a crease. -
Al, OK, still not that easy to do (for me), but I understand it. Thanks.

I do wish the workflow between SketchUp and modo was a bit more fluid. Deformations like this are a one button task in modo.
