The Ram Manager Tools - Ram Defaults utility opens a dialog box where the user can preset nearly all of the criteria settings used throughout the RAM Structural System modules. For a more complete description of the options refer to the indexed wiki topics below.
Changes to the default criteria will only affect new models created using File - New. Existing models (or models that are created using File - Save-as) already have a full set of criteria associated with the saved file and those are not affected by changes to the defaults utility.
The exception to this rule is the settings for dxf output. Changes to the dxf layers, for example, will affect the next new dxf file created on that machine, regardless if the model being exported is new or old.
Alternatively, some users make a simple model with all of the desired criteria settings as a type of template file. Each time a new project is starting the template model is opened and then a File - Save-as is performed to start the new file using all of the template file settings. One advantage of this approach is that the template file can include additional information like load definitions, deck types or concrete section info. Another advantage of this approach is that you could have different template models for different types of structures (maybe one for hospitals in California and another for industrial buildings in Arizona where different types of codes and loads are applicable).
