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?
