Performance
The inertial viewer frame mode motion has various applications in: Inrul Viewerframe Mode Motion
where $\vecv rel$ is the relative velocity of the object with respect to the reference frame, $\vecv obj$ is the velocity of the object, and $\vecv_ref$ is the velocity of the reference frame. Performance The inertial viewer frame mode motion has
Inrul mode fails if snapping is active. Turn off or "Snap to Grid" temporarily. True inertial motion requires continuous values. Inrul Viewerframe Mode Motion
