Old bugs are floating to the surface again. Timeline disappears, Timeline marker disappears, view changes from perspective with ortho faces back to orthographic..

[to3dornottobe]

Few years back I had issues with a Timeline that completely disappears, Timeline marker that disappears, the view changes from perspective with ortho faces back to orthographic when entering a sketch and moving back to design again.

Now these issues are back again and more present than ever. 

The first 2 issues are solved by stopping fusion and restarting it again, but after about 5 times a day it starts to get old fast. The latter issue (perspective) is bugging me every single time now. It's annoying because it throws me off my orientation using a 3dconnexion mouse. I loose orientation when I expect perspective with ortho faces instead of orthographic.  It's a struggle to limp around the entire day this crippled way.

The spacemouse looses orientation too once it has switched, so you have to hit the 'home/reset view' button again to make it work again.

It's reproducible.

Hi,

Thanks for posting. First, can you confirm what build number you are using, from the Help > About box?

If you can reproduce the timeline disappearing, please provide a video. There are no other reports of this. Are you by chance opening step, sat, or iges files? When you open a non-parametric file, there is no timeline. You have to turn it on. I'd like to know if you think there's another way to achieve it, glad to test out what you recommend.

The timeline marker disappearing: Historically there have been at least 7 ways I personally know of to make this happen. Fortunately we've fixed most of them. However, there are still a couple ways to make this happen. If you can post a video using Autodesk Screencast it would help me understand what's going on, assuming it's reproducible.

Have you installed the latest spacemouse drivers? If you are on Windows there is a new integration with 3Dconnexion that requires you to install the latest spacemouse drivers as well as enable a preference in Fusion, under Previews, that will enable this rich integration. If you haven't done this yet, please give it a try and let me know what you think.

And last, the only way I'll be able to reproduce and debug the camera switching issue is a video that shows the entire Fusion application frame, such as one made with Autodesk Screencast. I don't know of other complaints of this recently, but perhaps I missed it. Glad to look into whatever you can provide.

Thanks!

Spacemouse is using the latest drivers, on a mac, it's due to the switch in view orientation that the zooming trips. 

The timeline issue is solved, haven't seen it anymore since the latest update of Fusion, 

but the view issue is still very present. Here is a full screen record of the issue.

Hi,

Your video shows somewhat expected behavior. When you use Perspective with Ortho faces, and look at a sketch orthographically, the view should be orthographic, not perspective.

What seems to be a bug is that Fusion will remain in Orthographic camera after the initial look-at action that occurrs immediately as you edit the sketch. If you exit the sketch, without changing the camera setting, does it return to Perspective with ortho faces again (in modeling workspace)? Your video doesn't show this.

Have you tried turning off Auto look-at for sketches in Preferences? If you turn this off Fusion will stop rotating to view the sketch orthographically upon edit or creation.

@Phil.E If I understand you correctly the vanishing timeline marker issue is resolved ? 

I must admit that I had not paid attention to the issue, but I can confirm that over the last few weeks of daily work on 2 very different computer setups I've not seen it occur once!

Awesome!

@TrippyLighting to be clear, there are a couple ways to make it disappear as far as I know. It's one of those issues that affects one thing (the marker) but has several causes. A few of these causes have been fixed in the last year or so.

Sometimes i don't want the auto look at sketch, sometimes i do. (when sketches are drawn onto an angle other than 90 degrees it can get fuzzy, with the feature enabled) I toggle the feature from on to off where i need it.

With the feature switched off it works as espected. It can be working 'as intended' but you loose your orrientation when trying to navigate. Combine that with the crippled way Fusion disables you to zoom in on some parts of the drawing (where 1 minute of scrolling/zooming in only brings you 1cm closer to the object, (where sometimes it just moves 1m in .5 second). (this behaviour works normal again when you hit the 'home view' again). For this it doesn't matter if you're using the spacenavigator or the scrollwheel on the mouse, zooming in is crippled sometimes.

I had that issue when i started this topic. It was in an imported step file, timeline enabled, and the component/body/sketch bar at the left side of the screen was gone too, Perhaps it was after an update. After restarting F360 again i haven't noticed any of this anymore

If you model in orthographic view, you'll notice that the zooming problems with the 3D mouse disappear.

In perspective mode, often it helps to get back to the home view and then zooming start behaving normally again.
