Joint to origin - why no rotation on

contactHDX5W — Fri, 08 Dec 2023 11:41:40 GMT

Hello Everyone,

I'm really new to fusion, trying to pick it up for a second time. I'm following along with tutorials online but I ran into an issue with joints. I imported a .stp file and tried using the joint function to move the object to the origin. That worked, but I was unable to rotate the component on the desired axis. I wanted it to lay flat. I used it as a reference regardless and created my new component for that sake of completing it. However does anyone know how to fix this so that it would lay flat on X/Z?

You need to always attach your model for questions about them. Please do so. If you do not know how to attach your Fusion 360 model follow these easy steps. Open the model in Fusion 360, select the File menu, then Export and save as a F3D or F3Z file to your hard drive. Then use the Attachments section, of a forum post, to attach it.

Sorry about that, here it is

Since you create the Profile sketch for the case on a different plane than you want the phone, the one Suppressed Joint in the Joints folder MUST remain Suppressed. Model is attached.

Hi,

1. Alternatively, you can also use Align.

2. The axes can be changed with a joint origin, but not with an rigid joint.

It would be interesting to see what tutorial that is. Could you provide a link?

The reason your object doesn't lie flat is because when you use a joint to locate the component to the world origin, it snaps perpendicular to the Z-Axis. So my fist suggestion would be to set up your preferences so the Z-axis points upward. That might differ from the tutorial but will be quite helpful as you move along in Fusion 360:

That helps you with future models, but does not help you help you with the current model. That can be achieed as follows:

Set your model view to the front:

Your model view in the viewport will rotate, so the Z-Axis points toward you, out of the screen, so-to-speak.

Then click again on the small triangle under the view cube and select this:

Now the faces of the view cube are labeled appropriately.

When you click on the home button beside the view cube, your phone is still oriented vertically.

To change that, click on a corner so the phone rotates to the orientation you want to be the home view.

Then, again, click on the little triangle below the view cube and select this:

Now your model is oriented flat and the home view is also what is represented in the icon in the data panel.

Reorienting the model in the viewport in relation to the origin axis after modeling stuff usually breaks items in the timeline and is really not necessary.

Hey Peter, the tutorial is here

Thanks for your help, I'm feeling a bit overwhelmed by your solution. Is this something that I would have to consider with any imported geometry?

Hi Gunther,

Thank you for the video. I'm a visual person so seeing it in action helps.

Im not sure why he uses a joint as opposed to align. Might be that a ridged joint can't move, keep in mind I'm on day 13 of these tutorials so I might not know what I'm talking about.

No, but I've already answered that in my post.

I explain the process in this video.
