Creating a Layout, Section and Elevation with dimensions using AutoCad

Aim: To create the Plan and Sections as shown in the Figures.

Assumption:

Door:

• D= 1.0x2.1m
• D1= 0.9x2.1m
• D2= 0.875x2.1m

Window:

• W= 1.0x1.0m
• W1=0.9x0.9m
• W2=1.20x1.20m
• W3= 1.5x1.5m
• W4=0.75x0.6m

Procedure:

• Open cad application in the pc and set all the limits required.
• Set the units as required for drawing. Set units in decimal and scale in Millimeters.
• Keep ortho on for easily drawing lines in right angles.
• Select construction line and draw the outer line of the wall.
• Select offset command and carry on the drawing as given in drawing.
• Here in given drawing there are 4 houses so carry one house after another.
• The each house is different in size, shape and dimensions.
• After selecting the house take wall thickness of outer as 250mm and inner as 125mm where ever required.
• So the respective wall thickness wherever shown in plan.
• After drawing the walls of one house next draw the second house.
• Same continue for all the other houses.
• After completing all the walls of all houses.
• Select trim command and trim off the extra lines and make a good corner.
• While trimming the lines watch the given plan again and again for accurate drawing.
• Now do the staircase part using given size and show the tread with 250mm.
• Next show the doors wherever needed with respective sizes.
• Select the size with respect to the ease of use.
• Use line command to draw the lines of door.
• Using trim command remove the unwanted lines.
• Once the doors are done now go with windows.
• Select the window size with respect to room size and utility.
• Keep the window in the centre of each room walls.
• Same as door use line command and draw the either sides of window.
• Next draw two lines so that it indicates the thickness of window.
• Now place the columns as shown and in the mentioned orientation.
• The drawing part of plan is now completed now start with the naming.
• Use text command to write the names.
• Do naming of every door, window and room using the text command.
• While naming set the text and arrow size in a way that they are clearly visible.
• Show the dimensions wherever the room is not in square or rectangle.
• This is also done where two rooms are combined.
• Hatch the all the columns using concrete hatch.
• Now draw the Chajja in all the sides of building of 600mm width.
• Keep some bearing in the either side of the window.
• Create a layer of dotted lines for showing Chajja.
• Make a layer of dotted lines for section lines.
• After completing all the drawing parts, now draw 2 section line one with x axis and another with y axis.
• In the line of X axis use a jump line for more accurate and clean cross section.
• Now start with the cross section part.
• Use construction line to draw the vertical lines of wall thickness that are coming in the section line.
• Draw one horizontal line and take it as base.
• Using offset command first draw all the floor height and show the thickness of slab.
• Draw the beams wherever required.
• Trim off the excess wall lines.
• In section AA staircase section has to be drawn, so start with the given rise and tread.
• Show the correct number of steps as mentioned. Once the steps reach the first floor stop it.
• Here make the other side stair or the other flight in dotted lines because that is not been cut in section line.
• Make a handrail using dotted lines.
• Then change the riser distance and keep tread as same draw till the mid landing and just mirror the previous steps.
• Make them dotted, so that they are not been cut.
• Take the steps using copy command till the terrace level.
• Not show the doors, the doors are ended in lintel bottom level.
• After the doors show window with respective sizes and width.
• Draw the OHT in the head room of staircase.
• Draw the parapet wall and provide a waterproofing coat in slab.
• The footing cross section is also provided.
• Do the required naming and required dimensions like total height and floor to floor height etc.
• Now start with the section BB drawing, the section line through the Y axis.
• Copy the plan and rotate it in the arrow direction.
• Now select construction line and draw the wall thickness.
• Take the horizontal line and make it as base.
• Do carry the same steps as in section AA.
• Here there is a balcony where the railings have to be done.
• Use polyline and draw a designed railing.
• Check the distance and make it fix there.
• In the other side we have also to show the railings.
• Draw the lintel with Chajja wherever it has been cutted.
• When the section drawings are completed then start with the naming and dimensioning work.
• The naming can be copied using copy command and pasted of previous drawing.
• Select the size of text and arrows so that are clearly visible and easily recognized.
• By following the above steps we can complete the whole Plan and Sections as given.

Result:

Note:

• The clear drawing of all the above is attached below in pdf format.
• Here i have considered 300mm and 150mm as wall thickness
