When you go to verify a tool path in CAM:
Toolpath --> Verify
the Tool Path Visualization window displays a '3D Dynamic' tab.
Tool Path Visualization
-------------------------------
Replay | 3D Dynamic
Sometimes this tab is grayed out. What controls this?
Solution
Development confirmed that the 'ug_visualize' license controls the select ability (i.e. grayed out / not grayed out) of the '3D Dynamic tab'.
When Toolpath --> Verify is selected, an actual checkout of the 'ug_visualize' license is attempted, and if successful, the 3D Dynamic tab becomes accessible (not grayed out); otherwise the tab stays inaccessible (grayed out) . In addition, there is no record of the failed checkout, nor error in the debug log (e.g. C:\Program Files\Siemens\PLMLicenseServer\splm_ugslmd.log) on the license server.
Notes
The 3D Dynamic tab will only be selectable (not grayed out) when the 'ug_visualize' license can actually be checked out. Just the existence of the 'ug_visualize' license in the license file is not enough to make the 3D Dynamic tab not grayed out and selectable.
