This is the result of my testing using driver 10.6.8 (which is an older one), unfortunately. In Revit, I am unable to navigate, whereas it is very slow in Rhino.Inside.Revit, compared to Rhino itself. Even though the settings were equal. Furthermore, I noticed that Rhino 7 does not adhere to the lock horizon setting. See screencast here: https://we.tl/t-5PjSw72ZKT (link expires in one week from now).
I updated to the latest driver, by checking and unchecking the lock horizon button, the lock horizon functionality works again. The issues still persist though, unfortunately. Both Rhino.Inside.Revit and Revit are read from Revit.xml for the button config, which I guess is to be expected. However, because Revit is not officially supported in the 3dconnexion software, the additional functionality found under Navigation Modes in the driver is not available. This means, lock horizon and any of the other navigation options cannot be used in Rhino.Inside.Revit, as opposed to Rhino 7.
Furthermore, the 3d mouse works fine when booting up Revit, but as soon as Rhino.Inside is launched, it stops functioning. In Rhino.Inside.Revit, the movement speed seems to be fixed as far as I can remember. Here are some additional screencasts made using 3dconnexion 10.7.2 (the latest driver downloaded just now), all the screencasts, including the one with the older driver were from Revit 2021, Rhino version is (7.4.21078.1001, 2021-03-19).
And the screencast for the latest driver: https://we.tl/t-jPTdKeeyB7 (link expires in one week from now).
I sure hope this issue can be resolved. Will you be communicating this with 3dconnexion @kike?
