Procedure:

Step-1)   Creating bedroom room (8.2x3.6) by rectangle.

Step-2) Use the command "Explode" and select the rectangle.

• Draw an off set 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 line in the bottom and in the top.

• Draw an off set 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 line command draw a line at a distance of 3.2 units from the left bottom end to up-wards 0.9 units. 

• Using line command draw a line at a distance of 3.2 units from the left top end to down-wards 1.8 units.

Result: The line diagram of 2-bedroom building is drawn 

 Cross section of load bearing wall showing foundation details.

 Aim: To draw the c/s of load bearing wall showing foundation details.

 Commands used:

• Line.
• Rectangle.
•  Trim.

Procedure:

Step:1 - Create rectangle by typing "REC" in command box.

• Specify the first corner point as (5,5).
• Specify the length of rectangle =0.9 units in command box.
• Specify width of 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 rectangle as 0.6 units the width of rectangle as 0.4 units.

Isometric view of steps.

Aim: To draw the isometric view of steps.

Commands used:

• • Line.
• • Isometric plane.

Procedure:

1. To work with isometric view -command "ds" - snap off, grid off. Put isometric snap on.

2. Make sure that ortho mode is on.


Step :1 - From isometric drafting select iso-plane left.

• Give command "l" and moving the cursor to -x direction(left) give 1 unit
• Moving the cursor to+ y direction (top), give 0.15 units.
• Moving the cursor to + x direction again give 1 unit and cursor to -y direction(downwards) give 0.15 unit.

Step:2 - Change the isometric drafting to iso-plane top

• Move the cursor to back and give 0.3 units from the last drawn point.
• Move the cursor to right direction and give 1 unit.
• Move the cursor to front and give 0.3 unit.
  
  

Step:3 - Change the isometric drafting to iso-plane right

• 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: The steps are drawn in isometric view.

Isometric view of gable wall.

Aim: To draw the isometric view of gable wall.

Commands used:

• Line.
• Isometric plane.

Procedure:

1. To work with isometric view -command "ds" - snap off, grid off. put isometric snap on

2. Make sure that ortho mode is on

Step:1 - From isometric drafting select iso-plane 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 downwards and 0.3 units to left.

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

• Draw 1 unit towards the right and 2.42 units downwards.

• 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 iso-metric right with the line command draw 1.0 unit to right side and 3.0 units upwards.

Step:4 - By using the line command draw a line from bottom left corner @1.5 units and extend line 4 units upwards i.e., 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 by using erase.

Result: The isometric view of gable wall is drawn:
