Computer aided design
This week I tried to model my project, with number of programs,
DraftSIght,
Rhinoceros,and
123D DESIGN I installed theme on my computer And start to experiment with a 2D sketch of a ball .


The program I found most easy is
123D DESIGN
I sketch a half circle in 2D.

After that i use the option called revole.

Now I enter 180 deg and
Get a 3D half ball, then I use the shell option.

Now I have only the shell of the ball.

Now I work on design of the shell I choose circular pattern,And then enter the number of balls I wanted.



The program is pretty friendly and in a day I got the hang of itAnd started to play with some weight design.



And then I just started playing with it a bit.



You can see the printed results
