Aligning Bodies also rotates the aligning body

[apostM2K9B]

I'm a low level amateur (only use the app every month or so) and have been aligning bodies using their faces for quite some time.  Doing so has always aligned the planes without rotating the orientation they had prior to the alignment.  Today, when I align the bodies, they are rotated what looks like 180 degrees, adding a step to each and every alignment.  I'm designing a newel post for my son's wife so lots of trim mitered and copied 4 times around the post, so lots and lots of suddenly new steps.  

Is there something new I need to turn off?

Can you provide screenshots of the operation you are trying to perform?  The more information we have, the easier it will be to assist.

Actually, the file would be helpful, rather than pictures (it just leads to more questions). Please share it here.

I was afraid you'd say that.  I always end up with the horrendous files on my creative journey of discovery.  I'll see if I can make a simple one that will replicate the issue.

Do you have a logical grounded component?

Why not use Joints rather than Align?

I have also had this issue upon one of the recent updates. 75% of the time, an Align Components when selecting faces causes the part to rotate and offset. We typically import STEP files of components and "assemble" them by using the Align command since we are just using Fusion as a panel layout tool for industrial control panel design and do not need joints. There may be very small tolerance/flatness variences in the manufactures provided files that is now causing this, but it worked great until a month or so ago. 

This new behavior has made using Fusion very difficult for our use case and hopefully there is a resolution.

Echoing this issue with components as well.    Started about a month ago, and did not happen before.  If I have two bodies/components roughly aligned, for unknown reasons it randomly flips the body/component to be aligned 180 degrees (aligning it).  If it does flip the body/component, it will repeat this behaviour.   It's annoying.  Running on a Mac.

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

Here is mine. As simple as it gets, two terminal blocks to align face-face. The align command of the interior faces previously stacked them as expected. Now it rotates by 180 and offsets as it aligns.

This is how it behaves when I boot up the file.  I believe my use of the align tool is creating the same issue you are facing, but in this case simply clicking the "flip" option seems to remedy the problem.  In addition, using the Joint tool on the same reference point pulls the terminals into position in what I believe is the desired manner.  Let me know if this helps!

There was a Fusion update a month or so ago that changed how align works. 

Normally when aligning, the selected face of the "From" object mates with the selected face of the "To" object. Now the object either flips over and requires me to click the "Flip" setting or I simply can't use align but instead have to use move.

Also, I can no longer use the enter key from my extended keyboard to trigger the OK button when saving files. Really annoying when muscle memory has me hit enter then need reach over to hit return. Seems to have happened in the same update as this align issue. The save dialog now looks like this though it used to look different, if this is any help.

Yep...that is EXACTLY what I'm talking about.  Anyone have any work arounds?

[apostM2K9B]

I'll have to experiment with your method.  The video when very blurry when you used it, so I couldn't really see what was going on.  There may be a change in my work flow that has to happen as I seem to select faces to align rather than points ON the face.  Thank you for the input.  

[apostM2K9B]

I did not use join because I didn't know about it.  See...ignorance IS an excuse.  I'll try it though.  Thank you.  

[jeff_strater]

@ErikHolley - I think you are correct.  I can reproduce this on a very simple model.  And, I do agree that this seems like a behavior change - I'm pretty sure it used to work so that the minimum rotation of components would take preference.  It appears to always favor a "flush" orientation.  I created Fusion bug:  FUS-131890 for this issue.

[jeff_strater]

I was notified that this bug has been fixed, and should appear in the next update (which, I think, is in July).  Apologize for the disruption...

[apostM2K9B]

If this is the biggest problem I have all day I'm in good shape.  Thank you for all the help and support.  

[jreeves3DVQG]

Thanks - This has been a big headache for the last couple of months. We typically use the right click -> align components, and this should really help in our use case for fusion.

[ErikHolley]

Hoped that this was fixed in the most recent release, but it's not. I've posted twice about this before and would love to see the issue resolved. (For all community members that respond to these aligning issues with advice about using joins instead... thank you; however, there are times when align is faster.)

This time I was putting together a 3D print plate and couldn't get a few pieces to align correctly. Here's the video and I've attached the F3D file.
