Is it possible to reorder parts in the browser in an assembly?
The help file said: (but it doesn't work....)
You can change the order of components in the browser to list them according
to design intent.
A component does not move relative to other components in the graphics
window, even when you change its position in the assembly browser.
Constraints between components that originate from the same parent
subassembly are retained.
1.. Click a component in the browser.
2.. In the browser, drag the component to its new position in the assembly
hierarchy and click to drop it.
