Detailed Explanation

The LINE command is used to create straight line segments in a drawing. To use this command, you start by entering 'LINE' or simply 'L' and pressing Enter. Then, you specify the starting point of the line by typing coordinates, such as (10, 10). After that, you can continue creating lines by giving the endpoint coordinates. By moving the cursor and using orthogonal (ortho) mode, you can draw perfectly straight lines in horizontal or vertical directions. You can also create a series of lines by specifying multiple endpoints one after the other and close the line drawing by typing 'c'.
- Chunk Title: CIRCLE COMMAND
- Chunk Text: ### CIRCLE COMMAND
It creates a circle.
OPTIONS:
1. CENTER AND RADIUS: Draw a circle based on a center point and radius.
2. CENTER AND DIAMETER: Draw a circle based on a center point and diameter.
3. THREE POINT (3P) CIRCLE: Draw a circle based on 3 points on the circumference.
4. TWO POINT (2P) CIRCLE: Draw a circle based on two points of a diameter.
5. TANGENT TANGENT RADIUS: Draw a circle tangent to existing objects with a specified radius.
COMMAND: CIRCLE or C.
- Detailed Explanation: The CIRCLE command allows you to create circles in your drawings. You have several methods to define a circle:

1. Center and Radius: Specify the center point and then the radius to define the circle's size.
2. Center and Diameter: Similar to the previous method but using the diameter instead of radius.
3. Three Point Circle: Specify three points that lie on the circumference of the circle, and the software will create the circle that passes through these points.
4. Two Point Circle: Requires two points that specify the ends of the diameter directly.
5. Tangent Tangent Radius: Allows you to draw a circle that is tangent to two existing lines or arcs.
6. Chunk Title: ARC COMMAND
7. Chunk Text: ### ARC COMMAND
   It creates an arc and is used to add curved segments to the drawing.
   THREE POINT ARC: Draws an arc using three specified points on the circumference.
   COMMAND: ARC or A.
8. Detailed Explanation: The ARC command is used for creating curved lines in your drawings. You can create an arc by defining three points: the start point, end point, and a point on the arc itself. This allows for flexibility in creating smooth and curved paths. The command starts with typing 'ARC' or 'A', and then you can sequentially provide the three points needed to define the shape of the arc you're drawing.
9. Chunk Title: D.PLINE COMMAND (POLY LINE)
10. Chunk Text: ### D.PLINE COMMAND (POLY LINE)
    A polyline is a series of connected lines and arcs created as one object. The width of the object can be controlled.
    COMMAND: PLINE or PL.
11. Detailed Explanation: The PLINE command is important for creating a polyline, which is a continuous line that can consist of multiple segments, both linear and curved. Instead of creating each line or arc as a separate object, using the PLINE command allows you to group them into one single object that can be manipulated as a whole. You start the command with 'PLINE' or simply 'PL', specify starting points, and continue defining additional points or curves as needed, effectively drawing a connected path.
12. Chunk Title: MLINE COMMAND
13. Chunk Text: ### MLINE COMMAND
    It is used to create a set of parallel lines with different properties in a single go.
    COMMAND: MLINE or ml.
14. Detailed Explanation: The MLINE command enables you to draw multiple parallel lines simultaneously. This can be particularly useful for drafting structures, roads, or any design where you need evenly spaced lines with consistent properties. By activating the MLINE command, you can specify parameters for the lines you wish to draw, ensuring that all lines created share the same styling or properties without needing to modify them individually afterwards.
