Voice Crossing

When writing for an orchestra should you avoid voice crossing?

I'm trying to figure out how the four part writing rules apply when writing for an orchestra

What style of music?

What style of music?

Aye! Well, then, I don't think it matters so much. Individual line is more important.

Thanks

voice crossing is an orchestrational tool, bringing out specific timbres of the instuments/voices

tools shouldn't be avoided, but used wisely.

avoiding voice crossing in orchestra is like holding the breath forever, is inevitable.

With an orchestra voice-leading becomes more complicated because you suddenly deal with 20-odd different instruments, all with a different tone and dynamic curve rather than four voices all with a (nearly) homogenous timbre. But as long as the orchestrational effect is coherant and the most important lines are the clearest there is no prohibition on crossing of voices. Voice-crossing in vocal music is generally avoided for practical reasons - it is more difficult to sing when the position in the texture suddenly changes.
