Creating a Floor plan, Footing detail and Isometric view using AutoCad

Aim: To create floor plan, footing detail and isometric view using autocad

 The objective is to use autocad tools such as offset, chamfer, dimension, fillets, ortho mode etc, and get well versed with it so that it would be easy to use autocad.

1. Aim : Cross-section of load-bearing wall over spread footing

Step 1: using the rectangle command, start by drawing the bottom rectangle, by giving the first corner of the rectangle, and then by giving dimensions command and then giving the dimensions of the rectangle.

enter  d for dimensions

enter the length =0.9

enter the width = 0.25

specify the other corneer

type l in the command line and press enter

specify the start point

specify the next point 0.20,0

specify the next point 0,0.40

specify the next point .05,0

specify the next point 0,0.40

specify the next point 0.50,0

specify the next point 0,0.60

specify the next point 0.30,0

specify the next point 0,-0.6

specify the next point 0.30,0

specify the next point 0,-0.60

specify the next point 0.50,0

specify the next point 0,-0.4

specify the next point 0.05,0

specify the next point 0,-0.40

Step 2

type l in the command line and press enter

specify the start point b

specify the next point 0,0.05

specify the next point 0.30,0

specify the next point 0,-.05

Step 3

type l in command line and press enter

specify the start point at c

specify the next point 0,1

specify the next point 0.30,0

specify the next point 0,-1

the rest of the diagram can be done using polyline and giving dimensions for polyline and using trim to trim unwanted lines

result : the drafting of cross section of load bearing wall over spread footing is done.

2.Aim : to draw cross section of isolated footing

Procedure :   

Step 1:  draw a line with command l and give 1 unjts

give command l and give the relative cordinates as 0,0.15

give the next coordinate as @0,1.6

give @ 0.28,0

next coordinate 0,-1.6

next cordinate 0.38,-0.25

next 0, -0.15 or close

Step 2: draw an offset with the command at a distance of 0.04 from the bottom line to top

give the command of o and selct the object and give the offset distance as 0.04

do the same at the right and left bottom end

trim the unwanted lines

Step3: give offset from the top line with an offset distance of 0.2units

give the command 0 and select the object give the offset distance as 0.2

select multiple option and 9 such lines

trim the excess lines

Result: the cross section of isolated footing is drawn.

3.Aim: Line diagram of two bedroom bulding

Procedure:

coomands used

line

rectangle

offset

trim

Step 1: creating bedroom with dimension 8.2x3.6 by rectangle command

Step 2: use the command explode and select the rectangle

draw an offset using the command o

in the command line enter o and specify the distance of 3.6 units from the left bottom end

draw an offset using the command o at a distance of 4.2 units from the right bottom end

Step 3: extend the two lines in the bottom and in the top

draw an offset at a distance of 0.3 between the two line to bottom side

repeat the same step and create two offsets

do the same process in the top

trim the unwanted lines

Step 4: using the line command draw a line at a distance of 3.2 units from the left bottom end to upwards 0.9 units

using the line command draw a line at a distance of 3.2 units from the top left end to downward 1.8 units

Result : the line diagram of two bedroom building is drawn.

4. Aim to create the c/s of load bearing wall with foundation details

Procedure: 

Step 1:  create rectangle by typing rec in command box

specify the first corner

specify the length of rectangle 0.9 units in the command box

 specify the width of the rectangle =0.45 units in command box

Step 2 : create another rectangle rec in command box

specify the first corner point which is 0.15 units from the starting point of first rectangle

enter the length of the rectangle as 0.6 units the width of the rectangel as 0.4 units

Step 3: create the thrid rectangle command rec

specify the corner point which is 0.05 units from the starting point of second rectangle

enter the length as 0.5 units the width of rectangle as 0.3 units

Step 4: create the fourth rectangle command rec

specify the first corner point which is 0.05 units from the starting point of second rectangle

enter the length of rectangle as 0.4 units the width if rectangle as 0.6 units

Step 5: draw the fifth rectangle command rec

specify the corner point as the corner of the fourth rectangle

click in dimension give length as 0.3 units and width as 1 unit

trim the unwanted lines .

Result : the c/s of load bearing wall with foundation details is drawn.

5. Aim : to draw the isometric view of the steps

procedure: using isometric plane

Step 1:

using isometric drafting : select isoplane left

give command l and move the sursor to -x direction , left give 1 unit

moving the cursor to + y direction top, give 1 unit

moving the cursor to +x direction again give i unit and cursor to -y direction downwards give  unit

Step 2: change the isometric drafting to iso plane top

move the cursor to back and give unit 0.3 units from the last drawn point

move the cursor to right direction and give 1 unit

move the cursor in the front direction and give 0.3 unit

Step 3: change the isometric drafting to iso plane left

copy the object drawn , ortho off

command co and specify the base point and place it to new point

repeat it until 4 steps are formed

Step 4: with iso plane right join the two ends with ortho off

Result :isometric view of steps is drawn.

6. Aim : to draw the isometric view of gable wall

Procedure:

To work with isometric view command ds snap off ,grid off ,put isometric snap on

make sure ortho mode is on

Step 1: from isometric drafting slect isoplane left

give command l and moving the cursor to right give 1 unit

pointing the cursor upwards give 3 units

draw 0.3 units to left and 3 units to downwards and 0.3 units to left

Step 2: using isometric rigt, take line command and draw line upwards of 2.42 units from the starting point of step 1

using isometric left again , using line command draw 0.3 units to left side and draw a line which intersects the top line

Step 3: using isometric right with the line command draw 10 units to right. side and 3 units upwards

Step 4: byusing the line comamnd draw a line from the bottom left corner @1.5 units and extend line 4 units upwards , total 3.25 units from bottom

Step 5 with ortho off  draw a line between the corner of left side and the projected line done in step 4

draw it to the other side also till it meets the right corner

step 6: draw the vertical line with ortho on 0.3 and join the vertical line using line from left and right end same as in the step 5 remove unwanted lines using erase

Result: the isometric view of gable wall is drawn.
