3) Grasshopper Navigation and Components

To Navigate in the Grasshopper:

Use the mouse wheel to Zoom-In and Zoom-Out as required.

Use the Left Button to pick the components from Tabs/Panels, to place on canvas.

Click and Drag with left button, to drag the component from one place to other on canvas.

We learn more navigation stuff as we need in future sessions. 

Grasshopper Components:

Let's see the Grasshopper component and its structure. 

The picture on Left shows the Grasshopper Component (Command). Left part of the component is used to feed (Input) the Values required by the Component. And the Output is received on the Right side of the Component. Most of the Components will have Input and Output nodes, few components will have either the input or output nodes.

To learn more on each of the component, Hover (rest) the mouse pointer on the icon of the component (on the Center of the component) to get the tool tip of what the component is and what its function, Similarly hover the mouse pointer on the Nodes (in this picture example on "A" or "B" or "L") to get tool tip for that particular parameter. 

The Bubble on the Top Right corner of the Component will show an error message, what the component is waiting (or needed) to proceed further. 

When ever the required data is provided into the component, the component change its color from (Orange color means warning, Red color means error) to Gray.
