the levels of detail have been replaced by model states but they don't work the same way they also have a different meaning ...
We need to restore the levels of detail in the various model states.
Designing large plants and designing with all the nuts and bolts removed makes a very useful sense. If I suppress the hardware with the model states I have to be very careful to apply the changes and all the model states are not immediate.
The Copy View Representation to Model State command does not work on subassemblies.
