In Creo 4 PTC changed the functionality with the new Notification Center. Prior to Creo 4 if a model was imported and it was not solidified then it was not immediately apparent to the user. Now with Creo 4 it defaults to failure to solidify as being an "error". Being an error means that those references can not be used for next higher assembly references and that error propagates to all next higher assemblies. This becomes a big problem when opening large vendor import assemblies.
PTC's solution for this is the config.val file which can be placed in the start-in/working directory. If a larger organization wants to change the failure to solidify to be "ignore" then the file needs to be copied to every users start up location potentially over riding the users local config.val file depending on how it is implemented.
This idea is to create a config option that allows a file path for the config.val file similar to the way that the mdl_tree_cfg_file config option works for the tree.cfg file. This would allow an organization to set it for the organization but also allow users to point to their own file if they need different settings.
