Any advise on where to find a 3D CAD file of a mechanism or system such as a Seahawk Helicopter

CVerheul
I recall there used to be an MSC employee that maintained a database with generalised CAD data for mechanical objects. Is this still maintained ?
 
Or does anyone has any advise where to find such a (not to detailed) CAD file of a Seahawk Helicopter ?
 
Thanks in advance,
 
Regards,

    Depends on what you want to do with the geometry.
    Importing CATParts internally converts it to parasolids; i.e. if you save the model from ADAMS, a parasolid file will be automatically created.
    The geometry appears as "solid" when right-clicking, i.e. you can assign a density and will get a mass and/or you can use them for contacts.
    On the downside model handling becomes severly affected with huge geometry (i.e. a fit command takes ages).
     
    You can avoid that by using a mesher (I use ANSA) to create a wavefront (obj), import it into ADAMS and then export the created shell as a .shl file. Then open the "real" model and import the .shl. It will look the same than before, but handles much faster (also you could coarsen the geometry on meshing).
    Sometimes you may get away with the option "consolidate to shells", but the outcome is usually not as pretty as what ANSA creates.
     
    Only culprit here: The entity is now of type shell and cannot be used for all contacts as before.
     
    It's like always in life: You can't have the cake and eat it ...
