Let’s turn on a modeling aid.
Now you will see some information next to your cursor as you use most tools.  From the menu at the top, choose: FILE > PROPERTIES Under modeling aids select Cursor Tool Tips
Check the boxes above and click OK. 
This entire tutorial will be created in TOP view.
Double click the word TOP to focus on that viewport. 
Each tool has many variations. Click and hold the rectangle tool on the lefthand tool palette
There are many ways to draw a rectangle. In this tutorial we’ll use: Rectangle: Corner to corner Rectangle: Center, corner Rectangle: Rounded rectangle
Other places to find the same tools: You can type into the command line or you can find them from them in the Curve menus at the top of the screen.

Before we start drawing, let’s talk about Osnap. Osnap is short for Object Snap. The Osnap menu allows you to choose from a list of ways that your cursor and shapes will snap together as you draw. You can select one or many as you draw.

Your Osnap panel is at the bottom. 
For now, let’s disable all Osnaps and enable Grid Snap (at the top of the screen)
Turn off all other buttons at the top of the window.  For now, let’s disable all Osnaps and enable Grid Snap (also at the bottom of the screen)
Turn off all other buttons at the bottom of the window. 
Rectangle Choose:
Draw a 1” x 1” rectangle by clicking on the Origin point (x0, y0) and dragging to the first major grid line intersection (x1,y1).

Rectangle Choose:
Draw a 2nd 1” x 1” rectangle by clicking on typing in the coordinates.
You don’t need to type anywhere specific, just select the tool and type: 2.5,0.5 (This is the starting x,y coordinate of the box) 1 and ENTER (this is the width) Then 1 and ENTER (This is the height)

Rectangle Choose:
Let’s use the dragging method again: Draw your third rectangle from xpoint 4 and ypoint 0 to xpoint 5 and ypoint 1

Now we’ll make a few additions with the help of the Osnaps. In the lower left, UNCLICK disable all and select these Osnaps instead:
 Now we’ll make a few additions with the help of the Osnaps. CLICK the Osnap button at the bottom
and select these Osnaps:

Rectangle Choose:
Now that the Osnaps are on, it will be easy to find the center of a rectangle. Drawing from the center of the 2nd rectangle you created, turn the shape into 3 concentric rectangles like this:

Circle Choose:
Drawing from the midpoint (of the line) of the 2nd circle you created and dragging straight up, turn the shape into a venn diagram
Drawing from the curve endpoint of the same circle (righthand side) and dragging straight up, add a third circle to the venn diagram.

Osnaps are really handy when a point doesn’t fall on a grid intersection.
Using:
Create a triangle inside your control point curve. Two of the corners of the triangle should line up with the midpoints of the curve.

Osnaps will even help you figure out where a fillet ends and a straight line starts.
Using:
Create a shape inside your filleted and chamfered diamond. Have the shape intersect the points where the fillet ends.

Now lets put each row of shapes on its own layer. Select the layer panel on the right by clicking the icon below.
 Now lets put each row of shapes on its own layer. Select the layer panel on the right by clicking the tab below.

Double click each layer name and rename as shown below:

Drag the cursor
around the bottom row to select all the shapes.
While the shapes are selected, rightclick (or control click) on Row 1 in the layer palette.
Choose:
 Drag the cursor
around the bottom row to select all the shapes.
While the shapes are selected, rightclick (or control click) on Row 1 in the layer palette.
From the contextual menu choose:
Change Objects to Layer 
Repeat this process and put each row of shapes on the corresponding layer.
The object will take on the preview color for the layer. This can be changed by double clicking the color box next to the layer name. Pick whatever colors you like as long as they are easily visible and look good together : ) 
Your turn!
Now select the my shapes layer by clicking inside the radio button and highlighting the layer.
On this layer, create a new row of 3 or more shapes. Create whatever shapes you want out of the tools covered in this tutorial 
Final touches:
Hold Command and Shift + Press E
Rightclick anywhere on the viewport grid and choose:
In the option window, uncheck these properties:
Then, close the window
This will only affect this document, but will make the drawing easier to see.
