ARCHICAD does not convert AutoCAD 2D elements automatically to 3D you need to model them.
If the Autocad file has a Model then you need to import it as an object to keep its 3D Settings (File-> Library and Objects -> Open Library Part -> External File)
If you already have modeled the facade en ARCHICAD then check that the layers are on in the 3D Window prior to rendering.
