Design Canvas

The Design Canvas is where you develop your model. It has two components:

• The Operations icons, which give access to all of Ravel's objects and mathematical operations; and
• The canvas itself, which is a space on which these objects and operations can be placed and connected by wires to perform data analysis, modelling, and displaying of results in Sheets and Plots.

A model consists of a number of blocks—imported data in parameters, Ravels, user-defined parameters, variables, constants, mathematical operators and the display elements (plots and sheets)—connected by wires.

The canvas is zoomable, either via the zoom buttons on the toolbar, or via the mouse scroll wheel. It is also pannable, either via the scroll bars on the right and bottom, or by holding the shift key and left mouse button together.

The canvas is effectively unlimited, however the scroll bars treat the canvas as pixels in size.
