I have been a user of AutoCAD. When I cooperated with another man to working for a big project, we have often used the command "XREF" (External Reference) in Autocad.
With the "XREF", You can move and rotate the object that be referenced from the exterior, but you can not edit this object in the main document.
The command "XREF" is very useful when you must deal the huge project. You can working for each part of the whole project in one time. After all the part have been accomplished alone, you can integrate all of parts to final project.
I want to know where can I find the similar command or function in Lightwave?
A lot of thanks for any help in advance!
