Hi John,
I found a way to replicate this issue 100% of the time on my computer.
Versions:
Inventor Professional 2024
Build 272
Release 2024.2
Inventor CAM Ultimate 2024
Build 11.1.0.21535
Vault Client Basic 2024
Build 29.2.88.0
2024.2 Update
Make a new assembly, and import a part, "Drag" the part (not "Pan"). Now the ViewCube is inactive until you click in the graphics window.
In my case where it caused the issue today:
-I placed a part (a machine table to represent a machining setup, like in my previous reply with the table and angle plates)
-I constrained this part using origin planes, leaving 2 Degrees of Freedom, as the part was not in the correct orientation initially
-I dragged the part while zoomed in to position for final constraining
-I went to change my view to line up the placed parts prior to constraining, but it was at this moment I noticed the ViewCube was inactive.
I opened a new assembly and confirmed the place operation itself does not cause the ViewCube to become inactive.
Since dragging seems to cause some sort of issue with the graphics window, maybe one of the developers could look into this interaction and find any other potential causes outside of drag.
--note: i was unable to replicate by using constrains, pan, free move, or free rotate, only drag.
Something else I've noticed:
While using "Drag", the default command for when you hold left click on a part in an assembly, the bottom left information box says "Drag component to new location" while "Free Move" also says "Drag component to new location" even though the operations seem to function differently. Given that Drag and Free Move are unable to produce the same result above.
