Animation in Fushion 360: rotate/orbit camera automatically zooms in. Help!?

[floortje.bijvoet]

When I would like to rotate (orbit) the camera view in the animation workspace, the model zooms in-and-out automatically. What happened? Is this a bug?

Hi, thanks for asking.

If you notice, the animation rotates your model opposite the direction you rotated it. That's because the "camera action" recorded in the timeline doesn't follow your mouse moves when you rotate the object. What the camera is actually doing is rotating the model for the "minimum" solution to go from A>B. "B" being the final position.

So in your case you show, the camera rotates the minimum distance to the final result, which is opposite the direction you rotated and produces the effect of the zoom. These calculations are by nature somewhat approximate because it's simply resolving the difference between start and end position.

Thanks,

Thank you for your reply Phil! Although it isn't extremely visible in this example, the zoom-in effect can be pretty intense. I will continue experimenting with this (I'm new, maybe I'm wrong). If I have a better example I will show you. 

Many thanks, Floortje

I can confirm to experience this behaviour too. The effect is quite strong. During orbit it suddenly zooms to fill the screen (roughly). It is pretty annoying. Right now I'm on 2.0.6670 and I would say the bug was introduced two versions before that. This behaviour is definetly new.

I think after playing a bit I can be more precise: Sometimes, I couldn't figure out the trigger, the Shift+MiddleClick+Drag combo which is expected to orbit the object zooms instead for a brief moment, as if Ctrl+Shift+MiddleClick+Drag was used. However the mouse cursor didn't change to the resize icon and after a brief moment it stops with zooming.

The effect I initially observed may however be something different. Sometimes when you Shift+double click middle, the object zooms in (and sometimes also out) in an animated fashion. That very much looks like the effect I'm seeing sometimes since one of the recent updates.

I'm sorry that I cannot reproduce this consistently.

I running Win10 btw.

Hi,

I assume there is no solution yet (if it indeed is considered  problem), but what would be a workaround?

I need to create an animation that simply rotates the model over the X-axis. Take very small steps I guess?

Any advice would be appreciated.

Thanks,

Rudi

Using Render:
If all you need is a turntable animation, you could always try a turntable rendering. Use the teapot icon rendering tool to render a starting view. Use local rendering. When that shows up in the film strip, double click it and pick re-render as turntable. That requires a few cloud credits.

Using Animation:

Rotate the entire model instead of the camera.  Using the move tool select the entire assembly from the browser node. The manipulator goes to the middle of the model, you just rotate it. This works really well.

Bruh how is this still a thing in 2022? why is it so hard to figure out how to rotate a model??? ;-;
