You can create a new simulation template by importing a 3D XML file. 
      
    
      Before you begin: You can import a simulation template only to the same release of Optimization
                    Process Composer from which it was exported.
- 
           From the top bar, click .
        
- From the Import 3DXML dialog box that appears, select the Path and the  Name of the file to import.
- 
          From the Import Options, select Import as
              New to create a simulation template that is a local copy of the original. 
          You become the owner of the new simulation template, and new internal identifiers,
            business rules, and lifecycles are applied to the new template. There is no connection
            between the new simulation template and the 3D XML file; changes to the 3D XML file will
            not be propagated to the new template.  
- 
           Enter a Duplication String that Optimization
                    Process Composer uses to name the new simulation template. (Optimization
                    Process Composer prepends the original name of the template with the text string that you enter.)
          
        
- Click OK.The imported simulation template appears in Simulation Finder in an
              Explore window; however, you must use Process Experience Studio to open the experience.
