====== Project ======



A project is an entity with a tree-like data structure that contains all development units of the modelled system. A project collects [[Block|blocks]], [[Material|materials]], [[Document|documents]] defined by the user into a file.

Each project contains one model, which can be organized into [[Sub-system|sub-systems]].

The [[Projects_window|Projects window]] lets you browse the full project as well as select the [[Projects_window#Active_project|active project]].
