Software Ideas Modeler is a CASE tool for Microsoft Windows used to describe and design software systems and processes. Its .simp file format is the program's native project format.
A .simp file can contain a UML project and the diagrams and model information associated with it. The project can be opened in Software Ideas Modeler for further editing and used to produce finished UML diagrams.
As far as we know, .simp projects can be opened and edited only using Software Ideas Modeler on Microsoft Windows. Use the program's Open command and select the project file.
Software Ideas Modeler projects are typically used to produce finished UML files. The program can export diagrams from a project to supported output formats, but those exports represent the diagrams rather than the complete editable project.
