SpaceMouse problem after update

[LauraWerner]

I just updated to the September, 2021 release, and I'm having trouble with my 3dConnexion Space Mouse. I've got an older one (5 years, maybe?) and it's just the 3d mouse, not the version with lots of extra buttons.

Is anyone else seeing what I'm seeing...?

When I'm *not* editing a sketch, the SpaceMouse works the same in sketch mode as it used to. If I rotate the mouse, any visible 3d objects will rotate as expected, based on their orientation on my monitor. For example, if I twist the mouse’s knob on its vertical axis, everything on screen rotates about a vertical axis running from the bottom center to the top center of my active canvas. A little dot appears to mark the center of rotation, but only while the rotation is happening.

Previously, it behaved that way when I was editing a sketch, too. Any visible 3d objects, as well as any visible sketch geometry, would rotate as expected about the center of the canvas.

Since the update, when a sketch *is* active, everything rotates around the origin. The axis of rotation is still in the correct direction (e.g. vertical on my screen if I twist the SpaceMouse), but it's offset to the origin. The origin always seems to be the center of rotation in sketch mode.

To me this looks like it might be a new bug introduced when the engineers fixed the "Spacemouse 4.0 – 3DConnexion I3DN" bug mentioned in the new release notes. But I'm new to Fusion 360 and I haven't used the SpaceMouse in years. If there are any settings I should try to tweak, please let me know. Conversely, if you think this is a bug, feel free to tell me there's a better place to report it. I figured I'd start here since I'm not 100% sure it's a bug yet.

Hi,

What’s new?

Fixed: Spacemouse 4.0 – 3DConnexion I3DN not working

We recently discovered that I3DN was not working anymore. The center of rotation was not set correctly. Instead, it was set in a fixed position, yet the 3DMouse has its own rotation point. Changing the center of rotation for the 2D Mouse (Shift + MMB) does not affect the center of rotation of the 3DMouse. This is now fixed and I3DN should work again.

Hi Günther,

Unfortunately, my sketch rotation problem started after I installed the update that was supposed to fix the Spacemouse 4.0 behavior. That's why I was suspecting that the fix for that bug might have introduced a bug affecting my older Spacemouse.

But today, the Spacemouse behavior when I'm editing a sketch is back to normal. I have no idea why; maybe things just got into a weird state yesterday and re-launching the Fusion360 app this morning got them back to normal. (Though I did restart it a couple times while trying to track down the problem yesterday.🤷‍♀️) I'll keep an eye on how it behaves the next few days and report back to the thread.
