Hello Marko,

The first you need to understand how to control elements in Allplan. Allplan has 9999 .ndw files and each file contains some special object and it is difference with Revit ( All elements in a Revit file). You can contains all elements in only one file like revit but It will lag.

We will try to separate the following Floor, type, zone , .v.v.v.v for instance :

1st OG :

Zone 1 : Wall - Slab - Beam - Column -

Zone 2 : Wall - Slab - Beam - Column -

Zone 3 : Wall - Slab - Beam - Column -

2nd OG :

Zone 1 : Wall - Slab - Beam - Column -

Zone 2 : Wall - Slab - Beam - Column -

Zone 3 : Wall - Slab - Beam - Column -

.....

If you have updates from Revit team, you need to change it in allplan.

...

For big update you need understand use Allplan API to update.

I will share my experience workflow as i use allplan for reinforcement drawing and revit formwork model.

1. Find the good way to model element in Revit and can import to Allplan.
2. Named each element with attribute, I control the element with attribute.
3. Allplan API to automatic update the model from ifc file. For instance : If I receive updates from revit ( IFC file) I will import the ifc file then run the tool to check the difference of geometry, material, .v.v.v. then tool will update the current model and brings the change for me.
