3. Aim: - draw the line diagram of a two-bedroom building

Procedure: -

• Creating bedroom room (3.6x3.6) by polyline.
• Command "PL" - click a point and move the cursor downwards (-y axis) and give 0.9 units
• As it gives continues lines, move the cursor to left (-x-axis)and give 3.6 units
• Move cursor to top(+y-axis) and give distance as 3.6 units and then cursor to right (+x-axis) and give 3.6 units
• Position the cursor to down (- y-axis) and give 1.8 units
• The step outline is created using line tool
• from the corner point of 1.8 units, line is drawn
• command "l" - line is drawn at a distance of 0.9 unit vertically.
• Then cursor is moved to + x direction and a distance of 1 unit is given
• again 0.9 unit is given moving the cursor to - y direction.
• The living room is drawn by polyline
• Command "pl" - from the last point start the polyline
• Give 4.2 unit in positive x direction.
• Move the cursor to-y direction and give 3.6 units
• Move the cursor to- x direction and give 3.6 units
• Create outline of step with line
• Command "l" -select the last point drawn
• Move the cursor to - y direction draw 0.9 units
• Moving cursor to - x direction draw 1 unit
• Moving cursor to + y direction draw 0.9 units.
• Creating step using offset
• Command "o" - give offset distance as 0.3 unit -select the object
• Click on multiple and move the cursor to the direction where it is to be drawn.
• Repeat the same on the other side also.

RESULT: - The line sketch of 2 bedroom is drawn:

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

Procedure: -

• Create a rectangle command "REC"
• Specify the starting point
• Click on dimension and give the length as 0.9 units and width as 0.45 units
• By polyline create rest
• Command "PL", with dynamic input on specify the first point 0.15 unt from the corner of rectangle
• With cursor pointing + y direction, give the distance as 0.4 units.
• With cursor pointing towards + x direction, give the distance as 0.05 units.
• With cursor pointing towards + y direction, give the distance as 0.3 units.

5. Aim: - To draw the isometric view of steps

Procedure: -

• To work with isometric view -command "ds" - snap off, grid off. put isometric snap on
• Make sure that ortho mode is on
• From isometric drafting select isoplane left.
• give command "l" and moving the cursor to -x direction(left) give 1 units
• 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.
• Change the isometric drafting to isoplane 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
• change the isometric drafting to isoplane right
• Copy the object drawn, ortho off
• Repeat it until 4 steps are formed
• Copy the horizontal distance of 0.3 downwards on the starting end of step with isoplane right
• Also copy the vertical distance of 0.15 on the last end of step
• With isoplane right join the two ends with ortho off
• line Command "l", select first point as the bottom point drawn

Result: The steps are drawn in isometric view.

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 that ortho mode is on
• From isometric drafting select isoplane right.
• Give command "l" and moving the cursor to left give 1units
• Pointing the cursor upwards give 3 units
• Draw 3 units to right and 3 units downwards.
• In isoplane right
• Again, take line command and draw line upwards of 2.42 units from the starting point
• Draw 1 unit towards the right and 2.42 units downwards
• Click on the end point, so that a closed figure is obtained.
• Change to isoplane left and draw0.3 units as thickness on the left side of figure.
• Move the cursor upwards and draw 3 units and join
• Give the thickness of opening, isoplane left
• 3 units towards left and 2.12 unit upwards.
• Extend the thickness line of opening 1.13 units upwards i.e., total 3.25 units from bottom
• With ortho off, draw a line between the corner of left side and the projected line
• Draw it to the other side also till it meets the right corner.
• Draw the vertical line with ortho on to join the centre portion and erase the projected and horizontal lines
• Copy both the inclined lines and join the right end.

Result: The isometric view of gable wall is drawn:
