LEARNING OBJECTIVES
After completing this lesson, you will be able to:
1. Create a Circle using 6 different methods.
2. Create Rectangles with Chamfers, Fillets, Width and Rotation.
3. Set Grids and Increment Snap.
4. Draw using Layers.
5. Control Layers.
6. Create Layers.
There are 6 options to create a circle.
The default option is “Center, radius”. (Probably because that is the most common method of creating a circle.)
We will try the “Center, radius” option first.
1. Start the Circle command by using one of the following:
Ribbon = Home Tab / Draw Panel /
or
Keyboard = C <Enter>
2. The following will appear on the Command Line:
Command: _circle Specify center point for circle or [3P/2P/Ttr (tan tan radius)]:
3. Locate the center point for the circle by moving the cursor to the desired location in the drawing area (P1) and press the left mouse button.
4. Now move the cursor away from the center point and you should see a circle forming.
5. When the circle is the size desired (P2), press the left mouse button, or type the radius and then press <Enter>.
Note: To use one of the other methods described below, first select the Circle command, then select one of the other Circle options.
Center, Radius: (Default option)
1. Specify the center (P1) location.
2. Specify the radius (P2).
(Define the radius by moving the cursor or typing radius.)
Center, Diameter:
1. Specify the center (P1) location.
2. Specify the diameter (P2). (Define the diameter by moving the cursor or typing diameter.)
2 Points:
1. Select the 2 point option
2. Specify the 2 points (P1 and P2) that will determine the Diameter.
3 Points:
1. Select the 3 Point option.
2. Specify the 3 points (P1, P2 and P3) on the circumference. The Circle will pass through all three point.
Tangent, Tangent, Radius:
1. Select the Tangent, Tangent, Radius option.
2. Select two objects (P1 and P2) for the Circle to be tangent to by placing the cursor on the object and pressing the left mouse button.
3. Specify the radius.
Tangent, Tangent, Tangent:
1. Select the Tangent, Tangent, Tangent option.
2. Specify three objects (P1, P2 and P3) for the Circle to be tangent to by placing the cursor on each of the objects and pressing the left mouse button.
(AutoCAD will calculate the diameter.)
A Rectangle is a closed rectangular shape. It is one object not 4 lines.
You can specify the length, width, area, and rotation options.
You can also control the type of corners on the rectangle—fillet, chamfer, or square and the width of the Line.
First, let’s start with a simple Rectangle using the cursor to select the corners.
1. Start the Rectangle command by using one of the following:
Ribbon = Home Tab / Draw Panel /
or
Keyboard = REC
