The Modeler window features a menu bar, a toolbar, a canvas, and a status area.
Figure 1. Modeler window
The menu bar and the toolbar provide access to commands that apply to a model and the Modeler window. On the canvas is where you construct models.
In the status area, the leftmost box displays information about the processing mode of a model, such as Writeable, ReadOnly, or Drag Mode. When you point to an object on the canvas, such as a module, a pipe, or a port, the box in the center displays information about the object. Other Modeler actions, such as loading a model or opening the Module Librarian are also displayed in this box. The rightmost box displays a progress bar when you run the model.
