I am working on a project to build a full front assembly of a truck chassis using files provided by the manufacturer.  All of these files were sent to me in .stp format and have since been converted to parts and assemblies.  I am currently focused on the front bumper which is saved as a .sldprt.  This file's design tree is surfaces and bodies instead of actual features.  The overall file size is just over 238 megs.   I am hoping there is a way to increase performance of this model by way of reducing file size, Defeaturing?, etc.  Is there any easy way to go about doing so?

Thanks,

Neal
