Basic alignment of components

[Anonymous]

I have the following model:

I managed to do the sketches, extrusions and joints, but I'm struggling to position the modules correctly relative to each other.

Obviously, the cylinder should be

1. parallel to the z axis
2. centred relative to the axis of the flywheel on the y axis
3. positioned correctly on the z axis (I guess its obvious what I'm trying to do)

It should be pretty easy so I'm wondering if I got something fundamentally wrong about Fusion - I was e.g. expecting to be able to type in absolute coordinates relative to the origin somewhere.

Also, I wasn't able to find any resources on this - the tutorials always start with a already properly aligned part.

Thanks for any help!

Ideally, I would like to be able to put an axis through the cylinder, align it parallel to the z axis and perpendicular to the axis through the flywheel.

However I can't find an option to make axes perpendicular to each other, or parallel to an axis of the coordinate system.

It is easier to help with your file, and showing you things with your data.

There is a good reason - tutorials start already aligned,

it is much easier to avoid your problem if you do.

However without the full screen of browser and history if any, our responses will be limited.

Might help....

I shared the design here.

Thanks for the help!

File as I found it, only needed aligning the cylinder / piston rod, with the centre of the flywheel. in the side view,

I positioned the cylinder by eye, as the joints have your assembly working.

unground the cylinder to move if you wish, (click and drag works)

Animate the model with Rev2 Joint, you will see the piston and cylinder are out of position to give you practise.

As you have no holding structure for the cylinder, it is all academic at this stage.

You can't delete sketches after making bodies in Fusion, without receiving the yellow warnings, 

Fusion works best without warnings in the timeline.

What do you mean by "I positioned the cylinder by eye"?

I need it to be precise, and preferably locked relative to the axis of the flywheel.

I mean come on positioning basic bodies relative to each other can't be that hard can it?

For future reference: I found the best solution to be to work with construction planes.
