To work with circles.

To create circles we have various combinations depending upon our work.

1.Steps for center radius method.

This is the default method for drawing a circle.

  1. Do one of the following:
    • Click Home tab  Draw panel  Circle drop-down  Center, Radius.  Find
    • Click Home tabDraw panel Circle drop-down Center, Diameter.  Find
  2. Specify the center point.
  3. Specify the radius or diameter.
OR

Command: C (Enter)
CIRCLE
Specify center point for circle or [3P/2P/Ttr (tan tan radius)]: click at center point on your drawing.
Specify radius of circle or [Diameter]: Value of radius (enter)

2.Steps for center Diamter method.

Command: C (Enter)
CIRCLE
Specify center point for circle or [3P/2P/Ttr (tan tan radius)]: Click at center point on your drawing.
Specify radius of circle or [Diameter] : d (Enter)  //this option will select diameter as the input value.
Specify diameter of circle: value of diamenter (Enter)

3.Steps for 3 point method.

You can use this method when you have to create a circle passing from 3 points and radius or diameter of the circle is unknow.

Command: C (Enter)
CIRCLE
Specify center point for circle or [3P/2P/Ttr (tan tan radius)]: 3p (Enter) //this option will prompt autocad that you have to use 3point circle.
Specify first point on circle: Click
Specify second point on circle: Click
Specify third point on circle: Click


4.Steps for 2 point method.

You can use this method when you have to create a circle passing from 2 points and radius or diameter of the circle is unknow.

Command: C (Enter)
CIRCLE
Specify center point for circle or [3P/2P/Ttr (tan tan radius)]: 2P (Enter) //this option will prompt utocad that you have to use 2point circle.
Specify first end point of circle's diameter: Click
Specify second end point of circle's diameter: Click

5.Steps for tan tan radius point method.

The tangent is the point where an object touches another object without intersecting it.

  1. Click Home tabDraw panel Circle drop-down Tan, Tan, Radius.  Find

    The command starts Tangent object snap mode.

  2. Select the first object to draw the circle tangent to.
  3. Select the second object to draw the circle tangent to.
  4. Specify the radius of the circle
OR

Command: C (Enter)
CIRCLE
Specify center point for circle or [3P/2P/Ttr (tan tan radius)]: T (Enter)  //this option will prompt autocad that you have to use 3point circle.
Specify point on object for first tangent of circle: Click
Specify point on object for second tangent of circle: click
Specify radius of circle : vaule of radius (Enter)

6.Steps for tan tan tan point method.

Go to tool bar -----> Circle -----> tan tan tan




Specify first point on circle: _tan to Click
Specify second point on circle: _tan to Click
Specify third point on circle: _tan to Click

From command

From:  fro (enter) From command is used to draw a line or any objects base point at a specific distance from a particular reference point. (Video link attached at the end of commands)   Command: L LINE Specify first point: fro Base point: Click at corner A <Offset>: 5 Specify next point or [Undo]: fro Base point: Click at corner B  <Offset>: 50 Specify next point or [Undo]: ESC click here to see how to use from command.

Co-ordinate systems

Hello Friends,             This is my first blog on AutoCAD tutorials. I won’t waste time on overview of AutoCAD and its uses which everyone knows. I will start directly with Co-ordinate systems of AutoCAD.             Co-ordinates systems are not of more use left in recent versions but still knowledge of co-ordinate systems is important as this keeps your mind sharp.  ABOUT CO-ORDINATE SYSTEM:     If you want to make any object in autocad you have two options.  1. you can directly click at any know point or  2. you can specify co ordinates of the point in command box. CARTESIAN AND POLAR CO-ORDINATE SYSTEM: Cartesian co ordinate system works only on linear distance. it have 3 axis X,Y,Z. when u specify any point with (+ or -) sign it prompts autocad to move along positive axis or negative axis at a specified distance. while working in 2D drafting, ...

poly line command

PolyLine Command: Command: PL PLINE Prompts common to Line and Arc segments: Close:  Connects first and last segments to create a closed poly line. Half width:  Specifies width from the center of wide segment to an edge. Width:  Specifies width of next segment. Points to remember while working with width and half width: The starting width becomes the ending default width. The ending width becomes constant for remaining segments untill you change the width again. The starting and ending points of wide line segments are the center line of segment. Typically, the intersections of adjacent wide polyline segments are beveled. No bevelling is performed for non tangent arc segments, very acute angles, or when a dot dash line types are used. Undo:  Removes most recently created segment. Prompts only for line segment: Arc:   Begins creating arc segments tangent to previous segment.  Length:  Create a line segment of a specified length at same angles as that of ...
