Is there a way to make joints stay locked or unlocked?

[Noah_Katz]

My assembly has lots of moveable joints and I often want to keep some of them either locked or free while I work on a particular area of the design.

However, I'm constantly having to re-lock or re-release them, seemingly from doing almost anything other than just looking at the design.

Modifying components (via their sketches), moving through the timeline and back (which I guess happens when editing sketches), perhaps moving other joints, and I don't know what else.

Is there a way to make the joint setting stick?

Hi Mr Noah_Katz,

The Fusion360 model does not have joint lock functionality, at least directly. Indirect, although the cumbersome way is pointed out in the previous posts.
Instead, there is the option to lock particular kinematic types (motions) of joints. It is simple and easily accessible.

Additionally (after some rumblings) F360 has been 'upgraded' to expose this function in API.

My original post was based on locking a single allowed DOF, so as far as I'm concerned that's a minor semantic distinction.

My experience with this little lock feature button is that it only lasts until you click on another function or move another joint. For me, it does not "stay locked until you unlock it" as it says in the flyout when you hover over it. I see this as a glitch and wish they would fix it for all the reasons that Noah points out.

If you Lock a Joint, then press the Capture Position Icon, the Lock will be maintained until you Unlock it.

That works. Thanks so much for the info!

@Phil.E I assume that is not the intended way it's supposed to work. Could you please direct this to the correct team?

[Noah_Katz]

That makes sense, thanks!!

I need more info. In this image, the mailbox (letter box) door revolution is locked. I then edit/drag the Flag joint, and the door joint remains locked. If I can get this to fail, I can log a bug report. Please provide a video or simple design that shows the issue. Thanks for helping.

Attached you will find a video where I try and explain what everyone is talking about with the Lock Joint.  Normal practice, it to Revert Position when created a new Feature in an Active Component so the Lock on any Joint is lost.  If on the other hand, you select Capture Position when promoted, you will retain the joint lock.  Model I used is attached.

I responded to your Educational account, I will also tag you here @Phil.E

Thanks for clarifying. I see the issue now.
