3D Mouse Center of Rotation

EvanReese

It seems like the default center of rotation for a 3D Connexion Space Mouse is the origin. This works well if your part is pretty centered and you're zoomed out to see most of it. If I try to zoom in and edit a little detail it becomes unusable. Any suggestions? btw, I'm not a big Fusion user, but I did try this and noticed it works much better because it dynamically updates the center of rotation as you move around the part. I can't think of a scenario where I'd want the center of rotation to be off the screen.

It turns out this behavior to center on the origin was a regression that has been fixed in a recent 3DConnexion driver update.  See https://forum.onshape.com/discussion/comment/48922#Comment_48922 for more details on updating the driver.  (There is an extra step needed beyond simply updating.)

Thanks, @Evan
I updated my driver, but I'm having trouble finding the file they said to delete. I'm looking for the following:

</code>~/Library/Preferences/3Dconnexion/navlib/Onshape.user.config</pre>but only see<br><pre><code>~/Library/Caches...

That's all you see? Maybe it's a permissions thing. Can you open a terminal and enter:

cd ~/Library/Preferences

Thanks. I did that and pressed enter, but I'm not seeing anything different, granted, I'm not a master with Terminal. What am I hoping will happen?

Sorry, type 

ls 

to list the contents of the folder. You can then continue to lower folders using cd <foldername>

Thanks, I was able to get it figured out and delete that file, but the mouse is still not rotating in an ideal way when zoomed way in. I'm not sure if it's a bug or just how it is. It seems like the CoR is maybe the center of the assembly bounding box. Should the center of rotation be somewhere on the model that's close to the center of my screen? It still seems like the CoR is off the screen when I'm zoomed in.

same here, the CoR is not changing depending on the zoom level, and that's not right. I don't think it does that in Solidworks, the CoR should always recalculate itself to the center of the screen ideally, am I dreaming?

3DConnexion Properties to the rescue with their grayed out yet functional settings tab and checkbox for auto rotation center:

Now zooming in recenters rotation away from the origin right to what you are actually zoomed into.
