2.3.2. CIRCLE COMMAND

B. CIRCLE COMMAND: It creates a circle.

The Circle Command is used to create a circle in the drawing. Circles can be defined by various methods based on specific parameters like the center and radius, center and diameter, or by setting specific points on the circumference.

Think of the Circle Command like drawing circles in real life. If you have a compass, you can choose a center point, adjust the legs to a specific length, and draw a circle. Alternatively, if you don't have a compass, you could mark points around a round object and connect them to form a circle.

CENTER AND RADIUS: Draw a circle based on a center point and radius. CENTER AND DIAMETER: Draw a circle based on a center point and diameter. THREE POINT (3P) CIRCLE: Draw a circle based on 3 points on circumference. TWO POINT (2P) CIRCLE: Draw a circle based on two points of a diameter. TANGENT TANGENT RADIUS: Draw a circle tangent to an existing object with a specified radius.

There are several methods to create circles in the drawing:

1. Center and Radius: Specify the center and the radius of the circle.
2. Center and Diameter: Specify the center and the diameter instead.
3. Three Point Circle (3P): Select three points on the circumference to define the circle.
4. Two Point Circle (2P): Select two points to define the diameter of the circle.
5. Tangent Tangent Radius (TTR): Create a circle that is tangent to an existing object with a given radius.

Imagine a playground swing. The 'center and radius' method would be like choosing the swing's pivot point and how far out the swing goes (the radius). For 'two points', picture using two stakes in the ground to define the width of a swing set’s support (the diameter). The 3-point circle is like creating a circle around three children standing in different spots in a playground.

COMMAND: CIRCLE or C. 3p/2p/TTR/; pick center or circle enter coordinates from center. Diameter/;D Diameter; specify diameter.

To execute the Circle Command, type 'CIRCLE' or just 'C'. You then choose the method (3-point, 2-point, or TTR) and enter the necessary coordinates for the center or the radius/diameter. Following prompts will guide you to pick the points or specify the required dimensions.

Using the Circle Command is like ordering a pizza. You can specify the size (diameter) you want right off the bat or choose points (like where to place toppings) to define how big it will be. Instead of making it randomly, you are defining it precisely.

3p/2p/TTR/; 3p First point; pick first point. Second point; pick second point. Third point; pick third point. COMMAND: CIRCLE or C. 3p/2p/TTR/; 2p First point of diameter; pick first point. Second point of diameter; pick second point.

When creating a circle, if you choose the 3-point method, you must click or place the cursor at three distinct points that define the circumference. In the 2-point method, you only need two points that represent the diameter of the circle. This flexibility allows for precision depending on the design needs.

Creating with points is like drawing floor tiles. You could either mark three corners of a triangular garden bed or use two sides to mark a rectangular area. The method you choose can define how accurate or complex your design will be.

COMMAND: CIRCLE or C. 3p/2p/TTR/; TTR Enter tangent specification; pick first tangential object. Enter second tangent specification; pick second tangential object. Radius; enter radius of circle.

For creating a tangent circle, you'll select two objects that the circle will touch (be tangent to) and then specify the radius. This command is particularly useful when the circle needs to smoothly align with other elements in your design.

Imagine designing a park path that curves around trees. Instead of just going directly through them, you want to create circles that gently touch the edges of the tree canopy. The tangent command allows you to do just that, making the design more natural and aesthetically pleasing.
