Design Canvas

The Design Canvas is where you develop your model. A model consists of a number of blocks--variables, constants and mathematical operators--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 first mouse button together. The canvas is effectively unlimited, however the scroll bars treat the canvas as a $10000\time10000$ pixels in size.
