---------------
"Disable Translucency" option does not work if 'Visaulization Preferences'
setting "Translucency" is OFF
Steps to reproduce the issue:
1. Create a simple assembly having one child part. In the component create
a simple block.
2. In the 'Edit Object Display' dialog Change the 'Translucency' of block
from 0 to any value for e.g. 50 by dragging the slider bar of
'Translucency'.
3. If the setting [Preferences > Visualization > Visual (tab) > General
Display Settings (group) > Session Settings > Translucency] is OFF.
4. In the assembly if you turn off the setting [Preferences > Visualization
Performance > General Graphics (tab) > Session Settings (group) > Disable
Translucency], the block becomes translucent.
5. Make the child component displayed part.
6. Again turn off the setting "Disable Translucency".
7. Make the assembly as displayed part.
Note that the setting "Disable Translucency" is turned on automatically.
Thus the setting "Disable Translucency" doesn't remain off and due to this
the object is not shown translucent. It becomes opaque.
Solution
To maintain the setting "Disable Translucency" off irrespective of the
displayed part, you need to turn on setting "Translucency". The settings
"Disable Translucency" and "Translucency" are synchronized with each other.
