(Clue?)Īlso interesting is that orbiting on my 3DConnexion mouse can also show the same bug, occurring at exactly the same conditions as when using regular mouse. So maybe something in the shared code differentiating Free Orbit and Constrained Orbit is causing the problem, as Free Orbit has no need to make this distinction. Interestingly if you're to left-drag the cursor to the top or bottom (tumble the object), the camera orbits just fine without any twisting weirdness. This extra twist of the camera is the bug! #2 repeats as you keep dragging to the right and the camera’s path would actually run curving around a sphere even though the cursor has only moved to the right! If one is used to free orbit in other CAD apps it would be immediately obvious, like how you can “feel” a skid in a racing game.As the cursor is further dragged to the right, #1 repeats but right, in relation to this now rotated view, is no longer parallel to the ground plane, so the orbit is no longer planar!.As you begin to drag to the right, the view’s camera position gets translated fine - keeping same distance to the object camera's heading is adjusted to point to the object fine too but there is also a clockwise twist (positive rotation along the lens-to-object axis) added for no reason, so the view begins to rotate counter-clockwise and the ground plane is no longer horizontal.
Using spinning the object by left-dragging cursor to the right as an example: Hopefully these can help lead to a fix soon.Ī screencast of the exact problem has been posted by please refer to:Īssuming current view’s camera is pointing towards the horizon, ground is horizontal in the view, an object is at the center of view, no camera pivot is set. Recently I did a little experimenting to try to understand the problem better and I think I've also spotted a pattern of its occurrence/disappearance, so I’m posting to share my findings.
I’m currently on Mac version and the problem remains unresolved since my trial on PC almost 3 years ago, I'm guessing due to it's elusive nature. The installer will, after downloading files and applying patched, launch the 'fusion installer'.Hi, I am new to these forums but have been using Fusion 360 as a replacement for T-Splines for some time now.Īs a few others have posted before, the Free Orbit tool can have a bug where the camera follows an unintended path when cursor is left-dragged horizontally. It can be tricky to get to that window sometimes. Some native dialogs like a filepicker can pop up under a floating window from Fusion. The GUI's floating tooltip/toolsettings windows seem to float above anything, resize them once for a small amount to stop them from staying on top of everything, some menues also need to be clicked once too.
