Creation of geometries by Coordinate system methods using AutoCad

Aim: aim of this project is to draw geometric figures using line and circle tool

Introduction: using the imperial and decimal templates and the figures are drawn using one of the coordinates systems from absolute, relative and cartisian coordinates.

procedure:

P-1

procedure for P-1 is as follows

start->new->decimal units->using line command ->giving coordinates such as (2,1) and giving enter, likewise all coordinates are done by using absolute coordinates.

for relative coordinate system, we use relative coordinates instead of giving input as absolute coordinates such as making every point as origin and giving values as shown below figure 2

figure 3 is drawn using cartisian or polar coordinates as inputs shown in figure 3

practiced figures are as follows:

P-2

procedure for P-2 is as follows

start->new->dimensions as decimal->taking line command ->type coordinates such as (2,1) and press enter and proceeding with remaining coordinates as first done.

figure 2 represents that using of relative coordinates inputs as shown below

practiced figures are as follows:

P-4

procedure for P-3 is as follows

start->new->using decimals->using cartisian coordinates and line command, i drew this below figure

P-5

start->new ->using decimals->i used line command and with relative coordinates system, idrew this figure using the given coordinates in problem

P-7

start->new->using decimals->i used the line command and realtive coordinates system and i drew as per the given coordinates in the question

P-8

start->new->using decimals->i used line command and relative coordinates system to draw the below figure as per the given coordinates in the above questions

P-9

start->new->using decimals->i used line command and relative coordinates system to draw the below figure as per the given coordinates

P-10

start->new->using decimals-> i used line command and relative coordinates to draw the below figure as per the given problem

civil related problems:

profile wood

start->new->using decimals->i used line command and relative coordinates system to draw the below figure and the circle command is also used in the figure

queen post truss

start->new->using decimals->i used the line command and realtive coordinates system to draw the below figure

mono pitch:

start->new->using decimlals->i drawn the below figure using the line command and relative coordinate system. and the dimensions tool is also used the show dimensions

result:

i have completed the all asked questions for which i used the line command, circle command (if need) and related coordinate system to draw the figures. the coordinates are taken from the given question.
