About Arcs

Arcs are the curved objects which can be made by many combinations of  3points, by specifying start, center, angle, length, end, direction, radius.

Arcs always traces anti clockwise direction, if you want to change the tracing of arc in clockwise direction then press ctrl and start tracing you arc.

Following are the combinations which are used to make arcs.

1. 3 points method: 
  • In this method you have to simply specify the three points through which arc passes by clicking on respective points.

2. Combination of start center
  • Start Center End: In this method you have to specify start point of arc on your drawing by clicking over the point. Then specify your center point, the distance between start point and center point will be the radius of arc and then specify an end point. 
  • Start Center Angle: In this method you have to specify start point of arc on your drawing by clicking over the point. Then specify your center point, the distance between start point and center point will be the radius of arc and then specify included angle of arc in counter clockwise direction. Included angle will determine the endpoint of your arc. 
  • Start Center Length: The distance between start point and center point will be the radius of the arc. after that specify the chord length of the arc. chord length will determine the endpoint of arc and included angle of the arc.
2. Combination of start end
  • Start End Angle: By making arc with this method, you have to specify start point, enf point, included angle of arc. Radius and chord length of the arc will be decided as per included angle.
  • Start End Direction: With this method you can make an arc by specifying start point and endpoint. the direction is the tangential direction along which you have to make your arc.
  • Start End Radius: With this method you can make arc by specifying start and end point. you can specify numeric value for radius or specify it by clicking on your drawing. the distance between end point and the point which you will click on drawing will determine its radius.
3. Draw continous lines and arcs by "Continous": This will create a tangential line from the endpoint of your arc. and also if you want to create a tangential arc after a line you can use continous option.

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 ...
