AutoCAD Plant 3D

[#1]

First of all, I wonder the Reference.

If i draw the 3D model, why devide folder? (ex. structure. pipe, tank...etc)  Is it affectted the file size?

andthen how to attach reference setting?    Attach or overay... //   relative path or full path??

Second,

I attached Structure, Tannk drawing in the Pipe drawing. Almost i made my project.

But i had to change my computer, I was maded my project in the My document folder...

So i change folder path and attach the tank model again, but displayed diconnected marker. ( pipe water drop )

How to attach 3d model tank?? already drawing piping...
