I am Max 2010 user and as far as I know, yes you can. Not many formats to choose, but certainly you can export every bit of your model.
I am doing an educated guess on what you need. If you are having troubles with a complex model; perhaps you might want to export what you need into another 3ds max scene and then use your workflow to export into the sim.
In GMAX, there is a menu option File/Export Selected. This exports only the parts you have currently selected. This is in addition to the menu option File/Export, which exports the entire model. I assume he is looking for something similar?
This is the setup I use.
When starting a new project after your first save of the Max file, it doesn't have to be much work, it could be just your backdrop reference material setup.
Open the Aces Tools LOD and Export Tool
Open the File Properties and the Export dropdown menus.
In the File Properties, Create the GUID
Give it a Friendly: Name, then in the Export Tools menu click Export this Max file!
This will create an .X file and place it in the root folder of your project folder provided you set one up. Leave it there.
At this point you can forget all about it.
From this point on you can export your model using Max's file menu. You can use Export/Export or Export/Export Selected
Save as type EXP 1.0 .X file, I usually create an (export) folder in the project folder where I save the .X and the accompanying .xanim and placement.XML
