What Bryce needs is a right click to get locations which could then be pasted into the Transform dialogue IMO, but as I don't build complex stuff in Bryce I've never experienced this problem Joe. Be interesting to follow this to see what turns up though.....

 

Once in a while I look around,
I see a sound
and try to write it down
Sometimes they come out very soft
Tinkling light sound
The Sun comes up again
