AutoCAD Project 4: Step by Step for House plan

Commonly used command for drawing a plan:

• Construction lines- Lines which extend to infinity - Command :XL-V OR XL-H
• Offset - command "O" -give the offset distance -then select the object to be offseted and select the direction we need to offset
• Fillet- Used to create corners of room - Command"FILLET" - give fillet radius by default it is zero -then select the two lines by which the corner is to be formed.
• Extend- Command "EX"- seelct the object to where it should be extended - seelct the line to be extended
• Trim - Command "TR" - select the base line (the line from where it should be trimmed)-then seelct the line to be trimmed.( tr-double enter will help the lines to trimmed without seelcting base line)

Challenge :1

-First create a new autocad file with imperial settings.

- Make sure that in units the the type is "Engineering" (as the dimension is in feet and inches)and also set the precision.

- Set the limits with command "LIMITS" specify the left corner points and right corner points and enter zoom all ("z-a").

- Draw constructon lines by command "XL-V" ,for vertical and "XL-H" for horizontal.

- Trim the left side and top portion of the construction line .

Drawing bed1:

- Take offset of both construction lines of 9" .by command "O"-give offset distance as 0'9 in the command box.

- Then take the offset of 11'7.5" to the +x direction and offset of 12' downwards so that the room is formed.

- Again give offset to the both lines with 4.5" so that the wall thickness is created.

- Trim off the unwanted lines.

Drawing bed 2:

- Give offset from the wall thickness of bed 1 towards + x direction of 11'6" .

- Offset the 9" to create wall on right side.

- Extend the line of 12" from bed 1 towards this line. Command -"EX" select the line to where it should be extended (4.5" offseted line of bed 2),then select the line which is to be extended. (12' line of bed 1along with wall thickness)

- Trim off the rest of the line in + x direction and - y direction. "TR"- double enter -seelct the lines to be trimmed.

Drawing toilet :1

- Offset 4'6" downwards then also offset 4.5" wall.

- Extend the left side wall towards the line 4'6" and the wall

- From that line offset 8'3" towards + x direction and offset the wall of 4'5" also.

- Trim off the unwanted lines.

Drawing toilet :2

- Extend the wall thickness of bed 2 to the 4'6" line ( extention line of toilet 1)

- Offset a distance of 8'1.5" towards - x direction and also 4'5" wall thickness.

- Trim off the unwanted lines.

Drawing dinning and living room:

- Give offset of 11' from the wall of toilet and also the wall of 9"

- Extend the left wall towards the 11' line and 9" line.

- Use fillet to join this line and the wall of toilet 2.

- Give an offset of 8'7.5" to understand the partition between the dinning and living

- Trim off the wall thickness of dinning and offset it as 4.5".

- Drawing kitchen

- Give an offset from the dinning wall of 6'8" and give an offset of 9" for the wall thickness.

- Extend the left wall towards this line.

- Give an offset of 11" towards + x direction and offset the wall thickness as 9"

Drawing parking and staircase room :

- Draw offset of 12'6" to draw the parking ,then give offset of 9" towrads inside.

- Give offset 13'9.5" from the living wall towards downwards.

- Extend both side lines towards this line.

- extend outher wall of kitchen ,so that the stircase room is defined.

Drawing staircase:

Given: thread: 1'

riser: 6"

- Give a wall thicknes of 9" for teh staircase room.

- Divide the staircase room by giving ofset of 3' from the front wall thickness .

- Give an offset of 1.96" to show the handrail (Assume ,5cm is usually given)

- Draw offset of 1'(thread) to draw the stairs in plan view.

- Draw 9 offsets as there are 9 risers fro 8 steps.

- Trim of the lines betwwen the handrails and give the other side as dotted lines ( it indicates that it is the upward stairs ,not visible when viewing ground floor plan)

- For that select the lines and change the line type to ISO dash.

- Mark the direction of stairs.

Drawing doors:

- Trim all the door openings with their respective width D1- 3' , D2- 2'6", D3 -3'3".

- For open kitchen ,trim the line retaining a distance of 6'4" from right side of kitchen.

- Draw doors creating an hinge of 0.5" from the midpoint of both the wall ,then drawing a circle with one point on the midpoint of one hinge and other the midpoint of other hinge.

- Place the windows : for living ,take an offset of 1'3" ,this is where the window starts( as it is given)

- Using line command draw a line of 6' from the centre of offseted line inside the wall thickness.

- Draw windows whereever necesary : from middle portion of a wall draw a line,from the midpoint of that line give the distance ie the width of the window,then join the other side. w1-6' w2-4' v-2'

- Trim all the unwanted lines and fillet the corners with fillet radius zero.Command: "F" - select both the lines(fillet radius is zero by default)

.

- Drawing the kichen slab and cupboards:

- Offset a distance of 2' to make the kitchen slab.

- Draw the cupboard by creating a rectangle Command "REC"-specify base point - click on dimension -give dimension as 5' x 2'.

- Copy the rectangle to other bedroom also.

- Placing each component in Layer

- From layer property- create new layer - create 5 layers each for wall, door,window, stairs,kitchen slab and cupboard.

- Name each layer as wall, door, window, stairs ,kitchen slab and cupboard and give different colours,so that it can be identified seperately.

- Select the objects and place it in respective layers.

Challenge:2

-Select metric units as the dimension is in mm.

- Draw a circle with command "CIRCLE" select a centre point and give the radius as 1398mm.

- Draw another circle with same centre with radius 452mm.

- Draw an offset of 200mm from the inner circle to detremine the psition of the chairs .

- Draw lines along the dimater of the bigger circle.

Drawing chairs:

- Draw a rectangle with command "REC" giving dimensions as 400 mmand 200 mm.

- Draw an arc with start-centre and end method with the endpoints and centre of the side(400mm) of rectangle

- Give two offsets of 50mm outside the arc. Command"O"- give distance as 50 and select the object and join the endpoints of the offseted arc

- Draw another rectangle of 50mm x70mm for the handle of the chair Command :"REC" -seelct the base point and click on dimension and give as 50mm and 70mm.

- Copy it on the other side so that both handles are fromed.

- Fillet the corner of rectangle by 50mm Command"F"- give the fillet radius as 50mm and select the two lines. and trim off the unwanted line.

- Move the chair and place it such a way that it touches the offseted 200mm circle and the refrence diameter line.Command"M"- select the base point and move it.

- Mirror the chair to the opposite side -Command "MI" - select the base point and draw the reference line where we need to mirror .

- Rotate the chair and move it so that the chair in left side is created Command "RO" -select the base point and rotate to desired angle.

- Again mirror the chair so as to create chair in right side.

- Delete the lines and offseted circle.

Challenge:3

First create a new autocad file with metric settings.

- Set the limits with command "LIMITS" specify the left corner points and right corner points and enter zoom all ("z-a").

- Draw constructon lines by command "XL-V" ,for vertical and "XL-H" for horizontal.

- Trim the left side and bottom portion of the construction line .

Drawing Utility room:

- Draw an offset of 300mm from the left side of vertical construction line and an offset of 150mm from the bottom horizontal construction line.

- draw an offset of 2100 mm upwards and offset of 1900mm towards the right side and give the wall thickness of 150mm and 300mm respectively.

Drawing DH toilet:

- Draw an offset of 1700mm upwards and wall thickness of 300mm as it is the external wall,and a room is formed . Command "O"

- Trim off the rest of the construction lines.

- Create opening for doors :

- In utilities room offset a distance of 200mm from the wall and then give an offset of 828mm (opening). and trim it so that opening is craeted.

- For toilet, after an offset of 100mm , give another offset of 832mm and trim to form the opening.

- Create the door by creating hinge of 12.5mm, and then draw circle to the midpoint of other side of wall.Trim off the rest of circle to form an arc.

- Draw window of 728mm in the utility room and a ventilator of 631 mm in toilet room.

- Draw the duct shown behind the toilet room by offseting 201mm and 150mm wall thickness upwards

- Extend the wall of toilet towards it and offset 402 mm ,offset wall thickness as 150mm.

-Fillet the corners of the room.
