Need help with this challenge

[RJG]

the challenge I was presented with i thought was going to be easier than I thought until I tried it. I can do it with math and figure it out but I cant draw it in inventor with out doing the math. So here is the problem I got a ball in a corner touching the ground and the all the side walls. now I need to draw a ball behind the big ball and make it touch all the sides and the ground. im posting the files to use. I just cant figure out how to draw this. Like I said i can figure this out with math the answer, I just cant draw it with out the math. Could some one please give it a try and if they can do it tell me how they did it. This is the first thing I have come across I Havent been able to draw in iv. Thank you

Not sure if this is your answer, let me know.
Was utilizing Tangent, Inside constraints.

I am going to post what im looking for this will help explain what im looking for. I can do this by trial and error but havent found a sure fire way of drawing this. The purple ball is the one im trying to draw with out doing trial and error methods.

hello,

this pretty close to what you need. but all i did was guessing.

I find this a very interesting problem. Maybe down the road inventor will have the option to draw a sphere that is tangent to picked sides. Granted this is not a problem you run into at least I have not. It was just a challenge some one gave me and said it could not be done except for doing the math. I disagreed until i tried it. I always have been able to draw something in 3D until this.

Here's one solution.

Interesting aside, note that the part1 is adaptive. Change the dia of the
ball to say 5 and watch part1 update automatically NOT.

I came across the same problem. The adaptivity didnt work.

Sorry if this is irrelevant, I can't see what's posted in versions later then 6.

Radius of ball2 = (sqrt(3)-1)/(sqrt(3)+1) * Radius of ball1

approx. 0.267949

Oops - just read the orig. post again, you already know the math!
