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.
  1. acad.dwt 
  2. 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.
  1. 2D wireframe
  2. Conceptual 
  3. Hidden
  4. Realistic
  5. Shaded
  6. Shaded with edges
  7. Shades of grey
  8. Sketchy
  9. Wireframe
  10. X-ray
We can manage visual style using Visual Style Manager.

View:

There are ten basic view controls in AutoCAD.
  1. Top
  2. Bottom 
  3. Left
  4. Right
  5. Front
  6. Back
  7. SW isometric
  8. SE isometric
  9. NE isometric
  10. 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 we want to draw 2D objects, such as plan or section, we will use only 2 dimensional ( x and y ). 
  • WCS is an imaginary plane that is parallel to the ground. It is the default coordinate system.
  • Modifications made to the WCS result in UCS. It is the plane that you work on. It enables the user to draw 3-dimensional objects.
  • To create new UCS, type ucs in the command window than say New and specify 3 points on your new UCS plane.

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 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  Polyline

Polyline Command in AutoCAD - AutoCAD Commands

-
Image
Polyline Command Polyline: A polyline is a connected sequence of segments created as a single planer object. You can create straight line segments, arc segments or a combination of two. Polyline is also called PLINE and short form of pline is PL. You can also access Polyline command by clicking this icon. You can also modify polyline. There are some modifications as below: Arc Close  Halfwidth Length  Undo Width Sets the starting point for polyline If you specify the second point, you draw line segments. If you enter "a" (a for arc), you draw arc segments. ARC: The following prompts are displayed when you draw arc segments. End Pont Angle Center Close  Direction Halfwidth line  Radius  second pt undo width Watch the  video  about Polyline Command. Also, Like our  Facebook Page  and  YouTube Channel .
