How to draw a line using cartesian coordinate system on graph paper?

The Cartesian coordinate system in two dimensions (also called a rectangular coordinate system) is defined by an ordered pair of perpendicular lines (axes), a single unit of length for both axes and an orientation for each axis. The lines are commonly referred to as the x- and y-axes where the x-axis is horizontal and the y-axis is vertical. The point where the axes meet is taken as the origin for both, thus turning each axis into a number line. For a given point P, a line is drawn through P perpendicular to the x-axis to meet it at X and a second line is drawn through P perpendicular to the y-axis to meet it at Y. The coordinates of P are then X and Y interpreted as numbers x and y on the corresponding number lines. The coordinates are written as an ordered pair (x,y).

How to use object snap, ortho and polar tracking modes in AutoCAD

1. a)Open AutoCAD application from desktop shortcut menu. b)Now click on model layout tab. c)Draw a line by using line command. d)Turn ON the object snap icon from quick access tool bar. 2.Select Line tool from home ribbon. 3. Specify the first point of the line in the model space. 4. Now specify the second point of the line in model space. 5. Now turn on the polar tracking button on status bar. 6. Now the polar distance and angle shown at cross hair. 7. Pick another point of the line and press key to exit from line command. 8. Now again click on polar tracking button to turn off the polar tracking and click on ortho mode button on status bat to turn on the ortho mode. 9. Again active the line command and pick starting point of the line and move the cursor around the workspace. Now we can observe the cursor moves only either horizontal or vertical. 10. 11. 12. Now save the current document. BACK to Day-2 Lessions

How to use Cartesian Coordinates in AutoCAD

Cartesian co-ordinate system is used to represent the X and Y coordinate values. We can draw elements by using a Cartesian coordinate system in AutoCAD. Generally in Cartesian coordinate system the x and y coordinate values are separated with comma (“,”). 1. See the two-dimensional cartesian coordinate grid system in the below image. 2. Generally co-ordinate system represents with its x and y co-ordinate values enclose with brackets. The first value in the enclosed brackets is for X value and the second value in the enclosed brackets if for Y value. The below image represents the line from (2,1) to (4,5). Syn: Type "LINE" and press ENTER KEY from key board. (the data we typed is inserted in command window). Then type 2,1 and press ENTER KEY. Then again type 4,5 and press ENTER KEY. Press <Esc> (escape) key to exit from line command. 3. The bellow line is drawn from (-2,-1) to (0,0). Syn: Type "LINE" and press ENTER KEY from key board. (th

step by step procedure to changing dimension styles in AutoCAD

1. a)Open AutoCAD application from desktop shortcut menu. b)Select new document icon from quick access toolbar and open "ansi-a" template. c)Now click on model layout tab. d)Click on “LINE” command from draw panel. e)Now move the cursor to 4 units in X axis and 2 units in Y axis and pick the line stating point. f)Now move the cursor 2 units horzontally rights side and pick another point of the line. g)Like wise above steps move the cursor or cross hair to required points shown bellow image and pick the points to get the required shape. h)Finally enter “C” to close the line. i)And draw circle by using Circle command. j)And draw the center lines. k)Then apply it’s layers accordingly. Now click on Annotate menu to view annotate tools ribbon. 2.Now click on dimension style icon to view dimension settings dailog box. 3.Now click on modify button in dimension style manager window.

Advantages and disadvantages of AutoCAD.

Advantages of AutoCAD: 1. A mid range Software 2. User Friendly 3. Fulfills most of the professional needs of a mechanical engineer 4. Lots of Time saving (but not always) 5. Paperless Environment 6. Ease of Accuracy — e.g. joining of lines head to head is not possible manually with desired accuracy 7. Easy to edit 8. Ease of Repetition / Addition 9. Reproduction of Drawing is easy, rapid and reliable in terms of dimensional accuracy and precision. 10. 2D and 3D production of drawings is very easy. 11. Zoom Command Facility allows us to see the minute details on larger scale view. 12. A facility of Modeling and making Parts library is available. 13. Parent – Child relationship allows multiple editing in single command, means if one part is edited all other linked parts are auto edited 14. Layers option allows us to hide or show some specific details of a complex assembly drawing for clear understanding. 15. There is no limitation of a Drawing size. You can draw a 2 l
