rotating point to point

[BennPari]

Hi all, Im about 30 hours in to my fusion journey now and am finding some things very frustrating. Coming from over 10 years expierience in sketchup pro there are things in that programme which would take me a a matter of seconds that are taking ten times longer to do in fusion 360.

Like the attached picture for example;

Id like to be able to rotate the component (with the circled and arrowed holes) on the axis of the hole ive circled in white so that the other hole ive arrowed snaps into position with the hole on the component behind it.

Ive tried to do this for 2 hours and still not got anywhere with it. Please help my ineptitude 

Cheers Ben

Can you File>Export your *.f3d file to your local drive and then Attach it here to a Reply?

Simple enough, 

Measure the angle required, 

Rigid / Revolve Joint - set the measured angle in the dialogue.

(it's not Point to Point)

Might help.....

yeah sure , here it is. cheers

[BennPari]

thanks. is this the only solution? seems like a long drawn out process for what should be a 2 second job. is this just the way it is with fusion 360? im finding it like this on so many things i want to do with this programme that its actually starting hinder my work productivity . Im going to keep going with it because hopefully the majority of it is just down to the learning curve everyoone has to go through but god its frustrating.

Nothing is grounded, so yes you chase your tail, 

Nothing hard to do, you just need to know the angle.  Measure tool will do that.

Joint is easy enough if the assembly is grounded.

Blue sketch lines makes for unstable models.

Might help....

Thanks ill take a look.  When you say "grounded" is that just another word for locking components in place ?

[davebYYPCU]

All components in Fusion are free to move unless you prevent that.

Grounding locks a component in the current place relative to file origin.

Grounding, Rigid Groups and Joints are used for this.

Only the top level Component is locked by default.

You should have at least one logically Grounded component in an assembly (or Rigid Joint to assembly Origin).

All other components that are not going to have motion should have logical Joints to the Grounded component (they can be Grounded themselves if there is no chance of edit changes, otherwise use Joints so that they can update position as Edits are made).

Then add Joints that will return free Degrees of Freedom (motion).

Many of your sketches are not fully defined - this will surely come back to bite at some time.

Blue lines and white dots should keep you awake at night.

And do not ignore unresolved issues highlighted in yellow (or red) in your Timeline.  Stop and resolve immediately.

Ignoring known issues like this is why we have rockets destroy launch pad and lose control before mission completed.

Thanks , Looks like i need to go back to school on the "defining sketches" part . ill look into that first

Just to clarify what has been said here:  You should not think about this as "I need to rotate this component to get them to align", but, instead, as:  "what joints do I need to add to my model to get the mechanism to work as I want?".  That is the message that @davebYYPCU has given you with his solution.  You should not have to think about the alignment or the rotation, that math is for Fusion to compute for you.  That is just one advantage of Fusion (a mechanical CAD product) has over Sketchup.  Sketchup does not understand mechanisms or their function.

So, while the advice here about sketching and fully constraining your sketches is great advice, and you should listen to it, it does not actually solve your original question, which is more about assembly modeling.  Instead, focus on the joint system design, and, yes, component grounding is part of that.
