how to draw line in AutoCAD?

What is a line?

Two points connect to form a line.

Line Command:

Type "line" or "L" and press "Enter" or Spacebar".

Two different devices are used to draw a line in AutoCAD.
  1. Keyboard
  2. Mouse

With the help of a keyboard:

There are two ways to draw a line with a keyboard.
  1. Relative point entry system 
  2.  Polar point entry system

Relative point entry system:

  • Indicates a point's distance and it's direction (+ or -) along the x,y
  • "+" sign indicates the direction of line to the right side in the x-axis and upward in the y-axis.
  • "-" sign indicates the direction of line to the left side in the x-axis and downward in the y-axis. 
  • Ponts are specified as (x,y).



X and Y (X, Y):

  • x specifies the distance to the x-axis.
  • y specifies the distance to the y-axis.
Let's suppose you have to draw a line of length 20 units from the origin.
  • Type "line" or "L"
  • Press "Enter" or "Spacebar"
  • Specify the first point.
  • Type "0" for x
  • Type comma (,)
  • Type "0" for y
  • Press "Enter" or "Spacebar".
The first point is specified at the origin (0,0). Now you have to specify the next point.
  •  Type 20 for x
  • Type comma (,)
  • As we know, we are not going to the y-axis. So, press "0" for y.
  • Press "Enter" or "Spacebar"
  • Next point is specified.
  • AutoCAD automatically connects these points and form a line od 20 units. 

Polar point entry system:

  • Specify the point with an angle.
  • To specify a point enter a distance and an angle separated by an angle bracket (<)
The general form is (K<ANGLE)
  • K is the length of the line from the last point.
  • Angle specifies the direction of the line.
If you want to draw a line to right side, specify the angle as "0" or "360".

If you want to draw a line to left side, specify the angle as 180.
If you want to draw line upward, specify the angle as 90.
If you want to draw a line downward, specify angle as 270.

With the help of mouse:

  • Click the line icon with the mouse.
  • Move your cursor to the drawing area.
  • Specify the first point by left-clicking.
  • Move your cursor and specify next point.

what is the difference between line and polyline in AutoCAD?

Difference between Line and Polyline (Pline): The Line and Polyline are two commands with different properties in AutoCAD. In Line Command every time we click, the part between two points.  The Line Command allows you to create a single straight line or a chain of straight lines.  When we select a polyline it selected as a whole object. On the other side when we select Line it is selected as a single line segment.  We can edit Polyline with " PEDIT Command ". On the other side, there is no specific command to edit line. Pline Command can draw curve segments as well as line straight ones but Line Command can draw only line segments. A polyline can have width but a line has no width. After drawing a polyline, you can use the PEdit Command to reshape the polyline into a smooth, flowing curve based on the vertex points you selected but you cannot do this with the line. We can select one line among the chain of lines to edit the drawing. However, in the...

How to Draw Arcs in AutoCAD - Arc Command in AutoCAD

-
Image
ARC Command: ARC: Arc is part of a curve, especially a part of the circumference of a circle. Command: The shortcut key of ARC command is "A". You can also access ARC command by clicking this icon There are different options/ways to draw ARC in AutoCAD. The default one is 3-point. Other options/ways written as below: 3-Point Start, Center, End Start, Center, Angle Start, Center, Length Start, End, Angle Start, End, Direction Start, End, Radius Center, Start, End Center, Start, Length Continue 3-Point: In 3-Point, you need to specify three points with the help of a mouse or keyboard. These three points are on the circumference. Start, Center, End: First, specify the starting point of the arc then center and then the endpoint of the arc. Start, Center, Angle: The first point you specify on the screen is the starting point. Then you need to specify the center point as above and then give the angle to give direction. Star...

What is AutoCAD? CAD stands for computer-aided design and drafting. AutoCAD software is used to draw technical drawings using drafting tools. Templates: There are many templates in AutoCAD but we will discuss two of them. acad.dwt  acadiso.dwt acad.dwt is a template setup for imperial (units= inches), whereas acadiso.dwt is setup for metric (units= mm). Visual Style: There are ten basic visual styles in AutoCAD. 2D wireframe Conceptual  Hidden Realistic Shaded Shaded with edges Shades of grey Sketchy Wireframe X-ray We can manage visual style using Visual Style Manager. View: There are ten basic view controls in AutoCAD. Top Bottom  Left Right Front Back SW isometric SE isometric NE isometric NW isometric We can also manage view controls using View Manager. UCS: UCS stands for User Coordinate System.  WCS: WCS stands for World Coordinate System. The AutoCAD world is 3 dimensional, However, if...
