SolidWorks Users... How the H$!! do I model a golf ball?
« on: April 25, 2009, 11:10:06 PM »
I cant figure this crap out. Tried a pattern of a pattern and a couple other ways but still no luck. Anyone have any ideas PLEASE let me know as I have a project to do.

Let me fool with it real quick. I promise nothing, and neither does the scotch that will actually be attempting to perform the work.

That's not my rendering. I gave up after trying to place dimples. A quick google search yielded that.

I have found a couple different models but I was wondering how to do it myself cause I need to change the dimple shapes. Im doin a test of different geometries for a project. Sounds like you got hung up in the same area as me.

Thanks for the help

Um, I made one a couple years ago.  I can email it to you.  I used a patented dimple pattern, so it's probably not legal to use for some purposes, but it looks perfect.

I'll have to get it at work tomorrow.  Probably 2007 format if that matters.

To do it yourself, it's an icosahedron.  Start with a small slice then make a bunch of radial patterns.

Ok, I'll try that pattern. My final project for this class is just to model the airflow around a golf ball with different geometry dimples. Our group thought it would be fairly simple... that is until we actually tried to model the damn thing. The pattern of a pattern thing is messed up at the top and bottom of the ball.

So I found a tutorial and did one of those icosahedron things but still dont know how to apply it. Thanks for all the help, im really trying to model a ball with a hexagonal dimple to compare the air flow in ANSYS to the circular dimpled one. I tried an imported model but the details are to fine and ANSYS can not mesh the small areas between the dimples.

Thanks again,

You might have to take some liberties then.  There's regulations as to how big a golf ball can be. 
Hex dimples are going to be a pain to model, much harder than modeling the pattern itself.  That might actually crash some systems.
Did you get the assembly I sent you earlier?  I used the email address in your profile.  I made that model two years ago just to mess around with PhotoWorks.

Yea, I got that earlier, thanks. It doesnt really matter what the overall size is cause I can make them all the same size. I figure I could make the overall ball bigger or just decrease the number of dimples. Have you ever used ANSYS? That program SUCKS!!!! Everything we do on it the thing takes forever or comes back with an error. This project is going to be the death of me, especially since I am the best at SolidWorks in my group... and that aint sayin much.

SolidWorks is very easy to learn but also very easy to use incorrectly and end up with clunky broken models.

I don't do fluid analysis, we have other groups that handle that.  There's a FloWorks add-on for SW that might do something, or it might be mostly useless like other add-ons.
