Inventor Studio

I rotate object(A) in inventor studio and it works fine, then i constrain object(B) with mate to object(A) which means if you move object(A) then object(B) will move, and the animation is still fine, but then i constrain another object© to object(B) which means if you move object(B) then object© will move, and if you move object(A) then object© should move too, then the animation doesnt work at all.... (when i rotate object(A))

how to do this properly

Using Autodesk Inventor Professional 2012 64 bit, Windows 7 64 bit

Attach the assembly here.

It's the same no matter what assembly and objects they are.... I made a small assembly of very simple objects to demonstrate that it doesn't work

I don't know if the assembly will keep the animation i made if it didn't then just move part 1 down, it shouldn't work.. after suppressing part 3 you will see then that it will work

Everything works as expected in your assembly - but your assembly doesn't match your description.

BTW - in general you should be animating constraints rather than components.

I said rotate at first, but anything you do in 'animate component' its the same result, if it works for you but not for me then my software must be not working?

moving part 1 down using 'animate component' the other 2 parts that are mated together should move down too... but it doesnt work if there is more than 1 part

I made a video to show you, could you make a video to show me how yours works ?

BTW, when you animate constraints all parts move but how can i animate constraints here if i want to move part 1 down and the other parts to sit still and just follow it... are you saying i should make a new plane and then mate that to part 1 and the animate constraint of that ? but why doesnt the animate component work?

I recommend that you go through the Help>Tutorials and Skillbuilders

then search Google for Bill Bogan Inventor Studio tutorials

then search http://au.autodesk.com for Mark Flaylor classes.
