I have modeled a Baja vehicle using assembly wizard. I imported rollcage as a cad file....and also resolved all the attachments by replacing all the vehicle body attachments with rollcage cad file body.

But I am getting an error an 

Unknown symbol BLANK...Error resolving entity ROLLCAGE-cg under Model. [General]
here-Rollcage is the name of the cad file.
 
Can anyone help me fixing this error?
waiting for reply

    I think this is what is happening:

    If you replaced the Vehicle Body with CAD graphics, this can present some issues.  When you import CAD directly, an implicit CG location is created, but there is no direct way to reference this specifically as a CG location, since the CG Point hasn't been created.  The task wizard relies on know this point location.

    The easier way to solve this, in my opinion, is to import the CAD geometry as graphics only, and continue to use the original Vehicle Body CG location as your reference point for the CG.  This means you will need to manually update your vehicle CG location.  However, the frame itself usually does not incorporate all of the sprung mass of the vehicle, i.e. all the stuff that's attached to the frame (seat, instrument panel, gauges, etc).
