The Model Reader is an application that allows read-only access to models created with Vensim. The model must be either published as model (.vpm) or application (.vpa) or saved as a Vensim format (.vmf) binary file (normal Vensim models are saved as text .mdl files).
Publication allows you control over what can be seen by the people you send your model to. You can distribute the Model Reader free with your models so that others can simulate and analyze the models without using Vensim itself.
The Model Reader appears similar to Venism PLE but contains no sketch tools or ability to change or save the model. The Model Reader does contain a Game interface to allow models with games to simulate properly.
