Templates provide a quick and easy method for defining design details along a string for use in conceptual designs, complex detailed designs, and visualizations.
Created templates are stored with each project. They can also be written out and read in using a readable file format (*.tpl), making them flexible and easy to use on multiple projects.
For more complex urban design, intersections and roundabouts, Templates are impractical and not an efficient solution. For these cases 12d Model introduced the MTF modifiers to provide much finer control and provide all the power of string design without losing the ease of Template design in simpler cases.
The various tools for 12d Model Templates are described or watch this short video on how to manage them within your project;
