I need to know How to create cornices from 3d object (it has protrusions or holes) depending on any perimeter line of room

loft or sweep to general extrusion, turn on generate UV mapping so that it follows the path, then use displacement mapping to create the in and out details on the face.

Check out RailClone by Itoo Software.

 

There are a couple of images in the gallery that show detailed mouldings that are somewhat related to what you want to do.

As said above, you'll need to use a displacement map and use a Sweep modifier on a spline drawn around the top of your room. However you might have very slow render times with a disp map.

 

I'd model a small piece of it completely (with all surface features), then just copy that piece over and over.
