Are you able to upload a sample DWG that is having the issue?
Please try checking if you have anything stated as missing by clicking View > Scene Statistics. If so, please paste the contents of the window.
If the enablers are stated as missing even after installing the enabler and setting the loader year to the same year as the Object Enabler you are using, try deleting the NWC cache files that were created upon opening the DWG models in NavisWorks so that NavisWorks won't reuse them with the missing object data. These files will have the same name with the '.nwc' extension and reside in the same folder as the original DWGs.
The ADT/Architecture/ABS/MEP enablers are based on the new Object Modeling Framework (OMF), (like AutoCAD Architecture, AutoCAD MEP Civil3D, and others based on these) be aware that by default, geometry in NavisWorks depends on the display configuration in use when the DWG file was saved, i.e. if saved in a wireframe view in the AutoCAD-based application, it will appear as wireframe in NavisWorks.
If you still have missing items although there is nothing stated as such when selecting View > Scene Statistcs, please try the following:
- With the model loaded, select from the top menu Tools > Global Options > DWG/DXF/SAT
- Scroll down and unmark "Use ADT Standard Configuration"
- Click OK
- Select from the top menu File > Refresh
