[assembly]rooting concentric cylinders

[ingmotty]

hello to all, I should assemble two concentric cylinders in such a way that when I roote one, also rough the other solidally.
What constraints can I impose?

 

[gerod]

put a blocked axiality bond (the lock)
Not simple?
if you rotate the first you have bound, the other follows it (in practice it is as if they were solidarity)

or put a sketch in each cylinder....

or take a plane parallel to the rotation axis of the first cylinder and make it to the corresponding plane of the other cylinder.

This is the best method among those who have proposed to you. let you lose plans and sketches that complicate an operation for which there is already an appropriate relationship; that is the axial alignment with blocked rotation.

Obviously this method is not the most practical but it is useful if the two cylinders have precise angle references.

In this case you should use an angled plane in conjunction with unblocked axial alignment.

thank you for your trust!! :

Then I have some problem, have patience but I'm still in the first arms.
I create a new asm, and insert the first cylinder. if I want to make it rotate with the command moves part, it does not let me select it.

the first part you insert into a set is automatically bound to the ground, so with all 6 dofs locked, and then if it does not allow you to make any shift or rotation.
normally it is good like this, on this part go to bind others; If you want to move it you have to delete or disable the bond on the ground.

edit: I managed and managed to rotate the two cylinders simultaneously. Thank you very much for your help.

ps: but what are the 6 dofs?

 

[radio]

ps: ma cosa sleep i 6 dof?

You have to excuse me, but I took it a moment.

are the 6 degrees of freedom (grades freedom in space), i.e. the three shifts and the three rotations compared to the three reference axes.
Bye.

ehehehehehe
How don't you know what the dofs are?

I didn't know why we didn't speak the same language.:biggrin:
I am accustomed to calling them gdl:biggrin::biggrin:
