- From the line drawn in step 11, at a distance of 0.3, draw another line with the distance of 0.15 units vertically and 0.3 units horizontally.
- Continue it two more times, until 3 steps are created.
- Draw another rectangle above fourth rectangle, command -"REC".
- Specify the corner point as the corner of the fourth rectangle
- Click on dimension -give length as 0.3 units and width as 0.05 unit.
- Drawn the fifth rectangle command -"REC"
- Specify the corner point as the corner of fourth rectangular
- Click on dimension -give length as 0.3 units and with as 1 unit.
- Erase the unwanted line by "trim"
Result:
The cross section of load bearing wall over spread footing is drawn.
C2
AIM:
To draw cross section of an isolated footing.
Commands used:
- Line.
- Offset.
- Trim.
PROCEDURE:
STEP 1: Draw a line with command "l" and give 1 units.
give command "l" and give the relative coordinates as @ 0,0.15
Give the next coordinate as @ 0.38,0.25.
Next coordinate is given as @0,1.6
Next coordinate @ 0.28,0
Next coordinate @0, -1.6
Next coordinate @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 up wards.
- Give the command of "o" and select the object and give the offset distance as 0.04.
- Do the same at the right and left bottom end.
- Trim the unwanted lines.
STEP 3: Give offset from the top line with an offset distance of 0.2 units.
- Give the command "o" an select the object-give the offset distance as 0.2
- select multiple option a 9 such lines
- Trim the extra lines.
RESULT: C/S of isolated footing is drawn:
Line diagram of 2 bedroom building.
Aim : To draw line diagram of 2 bedroom building
Commands used:
- Line.
- Rectangle
- Offset.
- Trim
Procedure:
Step :1 - Creating bedroom room (8.2x3.6) by rectangle.
Step :2 -
- Draw an off set using the command “O”
- In the command line enter “O” and specify the distance of3.6 units from the left bottom end.
- Draw an offset using the command “O” at a distance of4.2 units from the right bottom end.
Step 3
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:
ISOMETRIC VIEW OF STEPS:
Isometric view of steps.
Aim: To draw the isometric view of steps.
Commands used:
- Line.
- Isometric plane.
Procedure:
- To work with isometric view -command "ds" - snap off, grid off. Put isometric snap on .
- 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 1unit .
- 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.
C6 ISOMETRIC VIEW OF GABLE WALL
Aim: To draw the isometric view of gable wall.
Commands used:
- Line.
- Isometric plane.
Procedure:
- To work with isometric view -command "ds" - snap off, grid off. put isometric snap on
- 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:
