I am trying to make a nucleus electron animation. But I am new to animation it seems.
I can't even get one sphere to revolve around another.
Must I manually place the sphere in it's positions or can I use paths?
About paths, can I use transfrom tools to move the sphere along the path or do I have to adjust the "green" value
that dictates the postition on the curve?
I just want one ball to circle around another one. Like a solar system, well in this case a atom.
Any tips would be helpful!

You can use paths, but you should read up (or watch a tutorial) on them to fully understand how to use.
My own gut would be to just attach the spheres together and rotate the first (making sure the pivot is in the center). That's certainly the easiest and you can do it in seconds.

Like Kelley suggested.
But, if you want the center sphere to be stationary because you have more than one secondary sphere rotating around it, you would move the pivot of those spheres so that they coincide with that of the center sphere.
From then on it's a simple key frame animation.

Great idea that worked with one sphere.
Hmm, maybe copy the both of them and just rotate the other two with the second also being at world zero.
Thanks

Will start experimenting with pivot points as it seems.
Thank you for the idea and your time Ani : )

I ended up doing this instead :)

See Screenshot.
1) Props/3D Blocks/ Sphere
2) Add 2 Spheres.
3) Re-size 2nd Sphere
4) Centre 1st Sphere in middle of Path, by Moving it.
5) Put 2nd Sphere on Path (Select Path / 1st Way-Point. Position 0. Drag Timescale Scrubber for desired speed. Select last Way Point Position 100) Play-back
BTW, Attaching Spheres as prev advised, wouldn't have the desired result.

One way to get a FULL CAPABILITY model of both rotation and orbiting... Example: Planet and Moon...
It requires two dummy props and two spheres.
a) Start with a central primary "planet" dummy prop
b) Attach the planet to the primary dummy
c) You can now rotate the planet relative to the primary dummy prop to make the planet rotate
d) Attach a secondary "moon" dummy to the planetary dummy
e) Rotate the moon dummy around the planetary dummy... its orbital speed is independent of the planet's rotation
f) Rotate the moon relative to the moon dummy for it's revolution speed (or leave as-is if it is Earth's moon)
Repeat steps "d/e/f" for any additional orbiting bodies.
If your spheres are a uniform color and perfectly smooth, there is no need to rotate them (just orbit), in which case you can skip half of these steps.
There you are. Total control.

BRAVO!!!!! Holy badgers whiskers.... SOMEONE has their head s c r e w e d on the right way. :P
KEY INFORMATION... "I AM NEW TO ANIMATION." Therefore:- Simplicity to start the ball rolling.
Nice one Viking. YOUR way you can spin the planets at one speed, then spin the moons at another and spin the orbits as you wish.
Quick! Clean! Concise!

And, Yes, before you ask.... I AM an Animator. xx

Yeah, as soon as Dennis wrote the word "dummy objects" I hit my head with the back of my hand.
He definitely has it scoped out -- I forget how powerful using dummies are (mostly because in other programs you can adjust things a bit easier without needing them).

Sometimes it takes a dummy to think of dummies... ;)
Glad I could contribute something helpful.

Daemonspike, you might find this thread useful too, we had discussed your project in it yesterday along with other solutions.
https://forum.reallusion.com/338593/Animating-a-locomotive-wheel-set
(from the above thread...):

I am late to this thread, I know, but could one separate the wheel/motion part of the model from the base and then import as 2 parts, and then set motion to one while moving in tangent with the other, that way you achieve a fake-rig? Or link both to a 3rd dummy prop of some type that would be the primary path mover?Tony,In essence that's what I did. This wasn't so much about animating the move part of the loco as it was trying to get the wheel mechanism to work automatically once rigged right. I still think that's doable with iClone physics, but rather than waste more time trying it I just went ahead and animated it by hand. After I did that I linked to the rest of the train and animated its movement (calculated by the circumference of the wheels, so the movement matches the wheel rotation -- that particular part I could do via a script when Python ever arrives. In point of fact I might have done most of this via scripting and may give it another shot when we have that ability). Okay, I see. Ironically, I got the idea from you. In the other thread about an orbiting path, you had mentioned you could orbit an object by linking it to the center object, which itself would be rotating. In that case I also imagined a nucleus having multiple electrons, protons, etc. at different speeds, and so you could have a stable nucleus with no motion, or its own animation, but in its same geography have multiple dummy sphere-movers as the axis points for the other orbiting sub-atomic objects.
